The Health Insurance Board (CVZ) initiated a study of the functioning of the dental care system for mentally disabled people in the Netherlands.Two independent samples were used for the study, each drawn from a subpopulation of people with a mental disability in the age-group 15-45: people who have always lived at home (n = 60) and people who have been at some time been institutionalized and as a result of decentralization now live outside of the institution (n = 52). Dental visits were in both samples remarkably frequent (95-100%) and relatively few problems with daily dental care were identified. However, the health insurance regulations were unclear to many parents and carers, and there were doubts regarding dentists' specific expertise. At first sight the results of this study do not give cause to assume that there are special barriers to access to professional dental care for adult people with special needs. For a definitive conclusion regarding the long-term effects of the...

Background: Oral health-related quality of life (OHRQoL) measures are being increasingly used to introduce dimensions excluded by normative measures. Consequently, there is a need for an index which evaluates children's OHRQoL validated for Brazilian population, useful for oral health needs assessments and for the evaluation of oral health programs, services and technologies. The aim of this study was to do a cross-cultural adaptation of the Child Oral Impacts on Daily Performances (Child-OIDP) index, and assess its reliability and validity for application among Brazilian children between the ages of eleven and fourteen.

In order to determine the effects ofa new approach to preventive oral health treatment for forensic psychiatric patients, 3 studies were carried out using a Dutch version of the Oral Health Impact Profile-14 (OHIP-14-NL), among Dutch forensic psychiatric patients. In the first study, it was determined that the psychometric characteristics of the OHIP-14-NL were good and that attention to oral healthcare contributed positively to quality of life. The second study, which made use of an improved version of the OHIP-14-NL indicated that patients with a high level of anxiety for dental treatment and poor oral health reported a lesser quality of life. The third study showed that an effectively carried out programme of personal oral care can play an important role in the reduction of halitosis and in the improvement of quality of life. Moreover, it appeared that the retrospective version of the OHIP-14-NL was a useful method for determining the correlation between quality of life and oral ...

Objective: To describe the reported oral health behaviours and perceptions of Indigenous Australians living in Darwin, Northern Territory and to compare those with estimates for Darwin and Australia derived from the National Survey of Adult Oral Health (NSAOH). Participants: A total of 181 Indigenous Australians aged 22 years and over living in Darwin, participating in screening for a wider randomised clinical trial, were included. Method: Information on socio-demographic characteristics, oral health status including oral health behaviours and perceptions was collected using a questionnaire. Differences between the Darwin study (DS) participants and Australians in NSAOH were made based on non-overlapping 95% confidence intervals. Results: Almost 72% of DS participants had last seen a dentist over a year earlier, compared to 47% and 39% of NSAOH Darwin and Australian participants, respectively. A higher proportion of DS participants usually visited a dentist because of a problem than NSAOH Darwin and NSAOH Australian participants. A higher proportion of DS participants had avoided or delayed a dental visit because of cost than NSAOH participants. Over three times as many DS participants rated their oral health as fair/poor compared to NSAOH participants. A higher proportion of DS participants had perceived gum disease and one or more symptoms of gum disease than NSAOH participants. A higher proportion of DS participants experienced toothache, felt uncomfortable about appearance of their mouth and avoided eating because of oral problems than NSAOH participants. Conclusions: A higher proportion of Indigenous Australians living in Darwin presented with non-optimal oral health behaviours and perceptions compared with both the Darwin and Australian general populations.

Background: To translate and validate the Chinese version of the Quality Of Life Radiation Therapy Instrument and the Head & Neck Module (QOL-RTI/H&N), a disease-specific scale to measure quality of life (QOL) for patients with head and neck cancer (HNC) who received radiotherapy. Methods: The QOL-RTI/H&N was translated and validated according to the standard process: a translation and backtranslation procedure, pilot testing and a validation study. HNC patients were enrolled from the Cancer Center of Sun Yat-sen University and assessed using the QOL-RTI/H&N, QLQ-C30 and QLQ-H&N35. Reliability (internal consistency reliability, split-half reliability and test-retest reliability), validity (content validity, construct validity, criterion validity and discriminant validity), and responsiveness analysis were performed to evaluate the psychometric characteristics of the QOL-RTI/H&N. Results: A total of 238 patients (99.2%) completed the questionnaire. Item RTI23 had 16.0% missing data. Other items had low percentages of missing data (0.4% or 0.8%) or no missing data. The average time to finish the scale was 9.8 minutes. Cronbach's alpha of the domains ranged from 0.41 to 0.77. The split-half reliability coefficients ranged from 0.43 to 0.77. All of the intra-class correlation coefficients were equal to or greater than 0.8. All of the item-own domain correlation coefficients were greater than those of the item-other domain. Confirmatory factor analysis showed that Comparative Fit Index, Normed Fit Index and Non-Normed Fit Index were equal to 1.00. Root Mean Square Error of Approximation was 0.01, with 90% CI (0.00, 0.10). The domain scores of the QOL-RTI/H&N were significantly correlated with those of the QLQ-C30 or QLQ-H&N3. All domain scores of patients in different radiotherapy stages were statistically significant (P < 0.05), apart from the speech domain. Conclusions: The Chinese version of the QOL-RTI/H&N is a valid, reliable and responsive scale to measure QOL in HNC patients and can be used to assess the effects of radiotherapy treatment on these patients.

The aim of this epidemiological study performed in 2013 was to analyze various clinical and radiographic data on oral health and compare the results to those of four cross-sectional studies carried out 1973-2003. In 1973, 1983, 1993, 2003, and 2013 random samples of 1,000; 1,104; 1,078; 987; and 1,010 individuals, respectively, were studied. The individuals were evenly distributed in the age groups 3, 5, 10, 15, 20, 30, 40, 50, 60, 70, and 80o years. Eighty-year-olds were not included in 1973. All subjects were inhabitants of the city of Jönköping, Sweden. The clinical and radiographic examination assessed edentulousness, removable dentures, implants, number of teeth, caries, restorations, oral hygiene, calculus, periodontal status, and endodontic treatment. The frequency of edentulous individuals aged 40-70 years was 16, 12, 8, 1, and 0.3% in 1973, 1983, 1993, 2003, and 2013, respectively. No complete denture weareryounger than 80-years old was found in 2013. During the 40-year per...

The Child Oral Health Impact Profile (COHIP) was designed to assess oral-facial well-being in school-age children as reported by the child and via proxy report from a caregiver. This article describes the development of the COHIP using a multi-staged impact approach recommended by Guyatt et al. (Quality of life and pharmacoeconomics in clinical trials. Philadelphia, PA: Lippincott-Raven; 1996. p. 41). There were multiple phases to the development of the questionnaire: (i) initial pool of items developed from the literature and expert review; (ii) face validity of items; (iii) impact evaluation of the initial item pool; (iv) development of positive items and face validity of new items; (v) impact evaluation of the revised questionnaire and (vi) factor analysis and final revision of the questionnaire. Factor analysis was completed on the final questionnaire using data from the impact evaluation in order to evaluate whether the COHIP measured independent conceptual domains. Factor analysis identified five domains: oral health, functional well-being, social/emotional well-being, school environment and self-image. Readability was calculated using the Flesch-Kinkaid readability score that was finalized at a 3.5 grade reading level. Finally, two response sets, and a revised format (e.g., including pictures, increasing font size, and shading every other item) were implemented to decrease respondent fatigue and increase accuracy of participant responses. The final questionnaire consisted of 34 items and five conceptually distinct subscales: oral health, functional well-being, social/emotional well-being, school environment and self-image. Subsequent papers present the validity and reliability of the COHIP.

Abstract – This paper reports the results of a study of the reliability of a modified version of the Index of Orthodontic Treatment Need (IOTN) for use in oral health surveys. Twelve non-specialist dental examiners were trained in the use of the Modified IOTN using a standardised teaching protocol lasting approximately 1.5 hours. Following a school-based calibration exercise it was found that nearly all the examiners achieved either good or excellent agreement (mean Kappa=0.74). The average sensitivity and specificity scores were 0.90 and 0.84, respectively. The Modified IOTN appears to overcome the training and reliability problems that often accompany the use of orthodontic indices by non-specialists in oral health surveys.

Objectives: To study the agreement between self-reported dental conditions and clinical findings in an adult population (20-84 years of age), and thus evaluate questionnaires as a tool in epidemiological studies of oral health, in general, and periodontal health, in particular. Material and methods: A questionnaire was sent to 900 randomly selected subjects in the age groups 20-29, 50-59 and 75-84 years. Of these, 723 subjects (81.0%) answered the questionnaire and 20% of them underwent a clinical examination. Results: As regards the remaining teeth, there was a mean difference of 1.4 teeth between the number indicated in the questionnaire and that found on the clinical examination. This difference was most marked in the older subjects. Eight of the nine subjects with removable dentures reported in their answers that they had removable dentures. Periodontal variables -we found significantly more subjects with pathological gingival pockets among those who stated that they had pockets than among those who answered that they did not (P ¼ 0.01; chi-square independent test). Gingival bleeding was common in those who answered 'Yes' than in those who answered 'No' to the question concerning bleeding gums. This difference was significant (P ¼ 0.05; chi-square independent test) in the three age groups. However, there was no correlation between the questionnaires and the clinical examination concerning tooth mobility. Conclusion: Questionnaires concerning oral status are valid concerning the number of remaining teeth and use of removable dentures. They are less reliable about specific periodontal variables, but can still become a valuable tool for epidemiological studies of periodontal health.

Fischman SL: Clinical index systems used to assess the efficacy of moulh rinses on plaque and gingivitis. J Clin Periodontol 1988: 15: 506-510. Abstract. The American Dental Association's Council on Dental Therapeutics has adopted Guidelines for acceptance of chemolherapeutic products for the control of supragingival dental plaque and gingivitis. The most widely used plaque indices are the plaque index (PI) and the Turesky index. Gingivitis has usually been assessed by the Loe and Silness method, although the modified gingival index of Lobene and a bleeding index reported by Caton and Poison have also been used. To date. 2 products have been accepted by the Council as being effective in helping control supragingivai plaque and gingivitis. These products were evaluated using clinical indices described in this review. The indices were selected from the many in the literature as being valid, reliable, and easily learned. Suggestions are made for criteria to be used in comparability studies.

The purpose of this study was to evaluate a new periapical index based on cone beam computed tomography (CBCT) for identification of apical periodontitis (AP). The periapical index proposed in this study (CBCT-PAI) was developed on the basis of criteria established from measurements corresponding to periapical radiolucency interpreted on CBCT scans. Radiolucent images suggestive of periapical lesions were measured by using the working tools of Planimp software on CBCT scans in 3 dimensions: buccopalatal, mesiodistal, and diagonal. The CBCTPAI was determined by the largest lesion extension. A 6-point (0 -5) scoring system was used with 2 additional variables, expansion of cortical bone and destruction of cortical bone. A total of 1014 images (periapical radiographs and CBCT scans) originally taken from 596 patients were evaluated by 3 observers by using the CBCTPAI criteria. AP was identified in 39.5% and 60.9% of cases by radiography and CBCT, respectively (P Ͻ .01). The CBCTPAI offers an accurate diagnostic method for use with high-resolution images, which can reduce the incidence of falsenegative diagnosis, minimize observer interference, and increase the reliability of epidemiologic studies, especially those referring to AP prevalence and severity.

The purpose of this study is to analyze health at the transition from the Late Antique (LA) to the Early Medieval (EM) period in Croatia. Results of the analyses of skeletal remains are compared with historical and archaeological data to test the hypothesis that the transition was catastrophic. An additional objective is to determine whether the transition was a uniform process, or differentially affected the past inhabitants of Croatia because of various local considerations. To accomplish this, four markers of health: cribra orbitalia, linear enamel hypoplasia, nonspecific periostitis, and trauma were compared in 981 skeletons: 477 from nine urban LA sites, and 504 from six rural EM sites. Data were collected by sex and age for individual, and for cooccurrences of various features. Because continental and Adriatic Croatia has different ecological features, data

Objectives: This is a clinical case of a 36-year-old Dutch male, patient in the Dr. S. van Mesdag Forensic Psychiatric Centre in Groningen. It demonstrates a short-time effect of a tailored oral hygiene self-care intervention in three sessions over a period of 3 months on halitosis and a patient's oral health-related quality of life (OH-QoL). Methods: In addition to a dental screening and professional oral hygiene care, a semi-structured interview was conducted by the dental hygienist, and questionnaires were administered. The questionnaires included were; the Dutch version of the Oral Health Impact Profile-14 (OHIP-14-NL; used as a measurement of OH-QoL), scales for expected social outcomes for having healthy teeth, attitudes towards oral hygiene behaviour (OHB) and dental anxiety. Results: Clinical observations showed an improvement in patient's OHB, while the extreme foetor-ex-ore was reduced to an acceptable level. A retrospective assessment showed that patient's attitude towards the recommended OHB together with his self-perceived OH-QoL had positively increased. Conclusions: This case highlights the value of professional individual oral hygiene instructions performed by a dental hygienist. It also illustrates that a patient's effective OHB may play an important role in the reduction in halitosis and self-perceived OH-QoL. Finally, the retrospective version of the OHIP-14-NL may be an adequate method to assess self-perceived OH-QoL within a relative short period of time.

Dental plaster casts of 235 Maasai, 116 Kikuyu and 61 Kalenjin children aged 3-16 yr were studied to determine the incidence and magnitude of diastemas, overbite, overjet and anterior open bite. The highest prevalence of diastema was amongst the Maasai (61.3%), of overbite (84%) and overjet (99%) amongst the Kikuyu, and of anterior open bite amongst Kalenjin (24%), with values greater than 0.4 mm up to 11.5 mm. Comparison of the mean values showed that diastema (1.77 mm) and overjet (4.4 mm) were greatest in Maasai, overbite (3.53 mm) in Kalenjin, and anterior open bite (3.50 mm) in Kikuyu. In the total sample, the prevalence and mean of diastema were 49%, 1.68 mm; of overbite 77.4%, 2.96 mm; of overjet 88.6%, 3.83 mm; and of anterior open bite 16.5%, 2.69 mm (with values between 0.4-I 1.5 mm), while 5.5% had an edge-to-edge bite (-0.54.5 mm)

The aim of this study was to determine the validity and properties of the Summated Xerostomia Inventory-Dutch Version in samples from Australia, The Netherlands, Japan, and New Zealand. Six cross-sectional samples of older people from The Netherlands (n = 50), Australia (n = 637; n = 245), Japan (n = 401), and New Zealand (n = 167; n = 86) were enrolled. Data were analyzed by using the Summated Xerostomia Inventory-Dutch Version. All datasets revealed a single extracted factor which explained about one-half of the variance, with Cronbach alpha values ≥0.70. When mean scale scores were plotted against a "gold-standard" xerostomia question, statistically significant gradients were observed, with the highest score seen in those who always had dry mouth, and the lowest in those who never had it. The Summated Xerostomia Inventory-Dutch Version is valid for measuring xerostomia symptoms in clinical and epidemiologic research.

This paper critically examines the different models of oral health aimed at representing oral health-related quality of life (OHRQoL) and explores the extent to which such models changed conceptually to accommodate current theories and empirical knowledge of oral function, impairment and disability. A critical synthesis of the existing literature based on a comprehensive yet non-systematic review using Ovid-MEDLINE was performed. Full text of manuscripts available on models of oral health and OHRQoL published in English between 1 January 1950 and 30 June 2013 were identified. Nineteen manuscripts were identified presenting and discussing various models of oral health and OHRQoL that are predominantly negative and linear. These models are mostly based on sick role-related theories and do not readily accommodate the biopsychosocial theories of oral health. Alternative portrayals have emerged to include positive behaviours and adaptive strategies dynamically, but have yet to influence patient care and the development of subjective OHRQoL indicators. Despite the multitude of graphical representations of concepts, dental research has remained somewhat &amp;amp;amp;amp;amp;amp;amp;#39;linear&amp;amp;amp;amp;amp;amp;amp;#39; in portraying the consequences of oral diseases as a one-way street. Although the conceptualization of oral health has evolved in the past 30 years, dental research still refers to it as the absence of disease in more than half a dozen models of OHRQoL focused mostly on dysfunction and disability.

Oral diseases rank among the most prevalent non-communicable diseases in modern societies. In Germany, oral epidemiological data show that both dental caries and periodontal diseases are highly prevalent, though significant improvements in oral health has been taking in the population within the last decades, particularly in children. It is, therefore, the aim of the Fifth German Oral Health Study (DMS V) to actualize the data on current oral health status and to gather information on oral health behavior and risk factors. In addition to current oral health monitoring, the study will also permit conclusions about trends in the development of oral health in Germany between 1989 and 2014. DMS V is a cross-sectional, multi-center, nationwide representative, socio-epidemiological study to investigate the oral health status und behavior of the German resident population in four age cohorts. Study participants are children (12-year-olds), adults (35- to 44-year-olds), young olds (65- to 7...

To investigate Nigerian children's and their parents' satisfaction with the children's facial and dental appearances and their desire for orthodontic treatment, and to compare their assessments of treatment need with those determined by an orthodontist. The subjects were 242 11-14 year-old schoolchildren randomly selected from private and public schools in the Ife Central Local Government area, Nigeria. A questionnaire was used to obtain information from the children and their parents of their liking of the facial and dental appearances of the children and the need and desire for orthodontic treatment. The children, the parents and an orthodontist used the Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) to assess the need for treatment. More parents liked their child's facial and dental appearances than the children liked themselves. Almost twice as many schoolchildren thought they needed (27 per cent) and desired (29 per cent) orthodontic ...

Objectives: To identify the predictors of early childhood caries and urgent dental treatment need among primarily African-American children in child care centers in the Delta region of Mississippi. The purpose of this study was to replicate predictors of caries and urgent dental treatment needs that were identified in an earlier study conducted in Delta child care centers and to assess additional caries risk factors not collected in the original study.Methods: Children in 19 child care centers were examined by the dentists, and the parents provided data on oral health practices, oral health history, and on children's oral health-related quality of life (QOL). The dentists also assessed visible plaque and tested levels of mutans streptococci. Predictors of caries and treatment need among children 24 to 71 months of age were examined using logistic regression.Results: Two parent predictors of caries identified in the earlier study (parent flossing and soft/sugary drink consumption) were not predictive in the current study. Parent history of abscess continued to predict their child's urgent need for treatment. Young children's level of salivary mutans streptococci, maxillary incisor visible plaque, and parents' reports of child oral health-related QOL measures predicted the presence of both caries and urgent treatment need. Some expected predictors, such as frequency of child's toothbrushing, were not predictive of caries.Conclusions: Parental abscess and parent's report of the child's oral health-related QOL are risk indicators for poor oral health outcomes that could be used by nondental personnel to identify young children in need of early preventive intervention and dental referral.

The aims were to give an overview and consider advantages and disadvantages of different approaches used to evaluate dental treatment need and to suggest an alternate Quantitative Summative Dental Treatment Need Index. Methods: The Medline Ovid database was searched for relevant articles published during the last three decades combining the terms "needs assessment," "dental care," "health services needs and demand." Results: There were substantial differences in methods used. Different modifications of the Decayed, Missing, Filled Teeth/Surfaces indices, complex quantitative summative indices, or simplified approaches were used to assess dental treatment need. Differing advantages and disadvantages of these methods can be identified. Previously used approaches have a common limitation for use in oral epidemiology. Conclusions: The suggested alternate Quantitative Summative Dental Treatment Needs Index focuses on an ability to compare both the total burden of treatment need as well as to make a distinction among specific treatment needs across populations. This new approach is an attempt to develop a comprehensive index for use in oral epidemiology with further revisions anticipated.

Background: The aim of this study was to explore the oral hygiene practices and oral health status of Italian postpartum women. Methods: A self-administered questionnaire assessed socio-demographic information, oral hygiene habits and frequency of dental visits. All women received a thorough oral examination within five days after delivery. Logistic regression models were used to estimate odds ratios and 95% confidence intervals for exposures of interest and the presence of 'severe' periodontitis. Results: Seven hundred and fifty women participated in the study; 99.1% brushed their teeth everyday and 59.9% visited the dentist annually. The mean frequency of sites with bleeding on probing was 16.1% and the median clinical attachment level was 2.1 mm. The mean caries experience score (DMFT) was 8. Severe periodontal disease was present in 21.9% of individuals. Patients who reported visiting a dentist only when in pain and women with three dental caries or more were significantly more likely to have periodontitis (OR: 1.6; 95% CI: 1.1-2.2; p < 0.05 and OR: 2.3; 95% CI: 1.5-3.5; p < 0.01, respectively). Conclusions: Given the possible association between maternal and infant oral health, and between periodontal infection and general health, antenatal care providers should collaborate with dentists to encourage all pregnant women to comply with the oral health professionals' recommendations regarding appropriate dental brushing techniques and the importance of dental visits.

The periodontal status of 106 type 2 diabetic patients was assessed and compared with that of 106 age-matched nondiabetics. Patients older than 20 years with type 2 diabetes mellitus were recruited from the outpatient internal medicine clinics at the 2 main hospitals in Irbid governorate, Jordan. Periodontal disease was more severe in type 2 diabetic patients than in nondiabetics, as indicated by significantly mean higher gingival index, periodontal pocket depth, clinical attachment level and tooth mobility. There was no significant difference in the mean plaque index between diabetics and nondiabetics. The severity of periodontal disease was significantly higher in patients with diabetes > 5 years than those with duration < 5 years.

The aim of this epidemiological survey was to analyze the periodontal conditions of 19-year old individuals in two rural county areas, i.e. Fyrbodal and Skaraborg, Västra Götaland, Sweden, with special reference to gender and socioeconomic grouping. A randomized sample of 506 individuals (Fyrbodal 250 and Skaraborg 256 individuals, respectively) was clinically examined with regard to oral hygiene, gingivitis, periodontal pockets and gingival recession. Bitewing radiographs were used for assessment of alveolar bone level (ABL) and dental calculus. A questionnaire-based interview regarding oral hygiene habits was included. A majority of the subjects (76%) claimed to brush their teeth at least twice a day, while interdental hygiene means were used daily by 4%. The subjects showed a mean plaque score of 47% and a gingivitis score of 56%. Forty-six % of the adolescents had a plaque score of > or = 50%, whereas the corresponding figure for gingivitis was 62%. The subjects had on averag...

Determinants of oral hygiene behavior: a study based on the theory of planned behavior Buunk-Werkhoven YAB, Dijkstra A, van der Schans CP. Determinants of oral hygiene behavior: a study based on the theory of planned behavior. Community Dent Oral Epidemiol 2011; 39: 250-259. Ó 2010 John Wiley & Sons A ⁄ S Abstract -Objective: The aim of this study was to develop an index for oral hygiene behavior (OHB) and to examine potential predictors of this actual behavior based on the theory of planned behavior (TPB). Measures of oral health knowledge (OHK) and the expected effect of having healthy teeth on social relationships were included too. Material and methods: Using an Internet questionnaire, 487 participants were asked about actual OHB, attitudes (ATT), social norms (SN), perceived behavioral control (PBC), OHK, and expected social outcomes (ESO). Based on a Delphi method involving oral health professionals, a new index for OHB was developed, including tooth brushing, interdental cleaning, and tongue cleaning. Results: Regression analysis revealed that the TPB variables (ATT, SN, and PBC) and OHK explained 32.3% of the variance in self-reported OHB. Conclusion: The present findings indicate that socio-psychological consequences play a role in oral health care.

Objective. The aim of the study was to provide a paleopathologic and radiologic overview of the jaws and teeth of 3 Egyptian mummies preserved in the Civic Museum of History and Art in Trieste. Computerized tomography (CT) imaging and postprocessing techniques were used to examine the oral structures. Study design. A 16-slice CT scanner was used (Aquilion 16; Toshiba Medical Systems Europe, Zoetermeer, The Netherlands). Scans were obtained at high resolution. Orthogonal-plane and 3-dimensional (3D) reconstructions were created along with curved reconstructions of the lower and upper jaws. Determination of decayed/missing teeth (DMT) and decayed/missing/tooth surfaces (DMTs) were made with 3D images. Results. Analyses revealed differences in the embalming techniques and state of preservation of the bodies. Marked wear of the occlusal surfaces was a characteristic finding in all of the mummies. The DMT and DMTs were low compared with values for contemporary populations. Two mummies had fully erupted third molars. All mummies exhibited bone changes consistent with periodontitis. Conclusion. The CT evaluations of the oral structures of the mummies provided insight into the dental status and oral diseases of these ancient Egyptians. The low DMT and DMTs values and indications of periodontitis may be associated with the lifestyle of these Egyptians. The fully erupted and well aligned third molars may represent a morphologic adaptation of the arches to the muscular activity associated with grinding tough foods.

The purpose of the study was to explore associations between family status, family income, family size, mother&amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s age at child birth, mother&amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s education and parents&amp;amp;amp;amp;amp;amp;amp;amp;amp;#39; national background and caries experience in 5-year-old children. This study is based on data from the Norwegian Mother and Child Cohort Study conducted by the Norwegian Institute of Public Health and the Public Dental Services. A total of 1348 children were followed from pregnancy to the age of 5 years. Questionnaires were completed by mothers twice during pregnancy and when the children were 3 and 5 years of age. Clinical and radiographic examination of the children was performed at the age of 5 years. Caries experience in the 5-year-old children was low; 89% had no caries experience (d(3-5) mft = 0). In multiple logistic regression having one or both parents of non-western origin (OR 3.4, CI 1.6-7.3), having had a change in family status from pregnancy to 5 years of age (OR 2.0, CI 1.1-3.4) and having mother with low education (OR 1.9, CI 1.3-2.8) were statistically significant risk indicators for having caries experience at the age of five. Family characteristics in pregnancy and early life were associated with caries experience in 5-year-old children. Primary care personnel meeting young children with one or several of these characteristics should consider referring the child to dental personnel to enable early initiation of health-promoting activities.

The purpose of this study was to assess the fluoride content of Ceylon Tea, which is a popular beverage throughout the world. The fluoride content of tea infusions prepared from different grades of tea leaves collected from different parts of the tea-growing regions (25 samples) of Sri Lanka was measured using a fluoride-selective electrode. Fluoride leaching was found to vary from 0.32 to 1.69 mg F/l, but there were no significant differences in terms of fluoride leaching between tea from different tea-growing regions or between tea of different grades. Dental fluorosis is widespread throughout the dry zone of Sri Lanka, and drinking water has traditionally been considered to be the main contributory factor to the development of fluorosis. However, diet, the consumption of tea in particular, may also contribute to the manifestation of dental diseases.

This survey was undertaken to assess the orthodontic treatment need in a sample of 9-to 12year-old French children (mean age: 9.77 years; standard deviation: 0.84) attending 12 different schools in the same geographic area of Ile de France. Two examiners used the Index of Orthodontic Treatment Need (IOTN) in order to estimate treatment need. Five hundred and eleven children (268 males, 243 females) who had not previously received orthodontic treatment were examined. Two examiners, who had been previously trained in the use of occlusal indices, screened all the schoolchildren. No radiographs, study casts, or previously written records of the children were used; the IOTN was calculated from direct examination.

Objective: to evaluate the relationship between oral health status and nutritional deficiency. Design: cross-sectional clinical study. Subjects: 324 institutionalized frail older adults (mean age 85). Measurements: structured oral examination including an evaluation of mucosa, periodontal state, caries prevalence and denture quality. The nutritional status was assessed using serum albumin concentration and the body mass index. Physical dependence was assessed using the Barthel index. To identify oral health disorders associated with markers of malnutrition we performed the Pearson x 2 test separately for edentulous and dentate patients. Subjects with at least one of the identified oral disorders were classified as having compromised oral functional status. Results: about two-thirds of the subjects were functionally dependent and half had either a body mass index <21 kg/m 2 or serum albumin <33 g/l. Among the edentulous, wearing dentures with defective bases or not wearing dentures at all were the factors most associated with malnutrition. In dentate subjects, corresponding identifiers were the number of occluding pairs of teeth (five or fewer, either natural or prosthetic), the number of retained roots (four or more), and the presence of mobile teeth. According to these criteria, 31% of the subjects had a compromised oral functional status. This was more frequently found in dependent subjects (37%) than semidependent subjects (18%; odds ratio, 2.6; 95% confidence interval, 1.4-4.8). Those with compromised oral functional status had a significantly lower body mass index and serum albumin concentration. Conclusion: specific detrimental oral conditions are associated with nutritional deficiency in very old people.

Clinical characteristics might be associated with temporomandibular disorders (TMD) because they are antecedent risk factors that increase the likelihood of a healthy person developing the condition or because they represent signs or symptoms of either subclinical or overt TMD. In this baseline case-control study of the multisite Orofacial Pain: Prospective Evaluation and Risk Assessment (OPPERA) project, 1,633 controls and 185 cases with chronic, painful TMD completed questionnaires and received clinical examinations. Odds ratios measuring association between each clinical factor and TMD were computed, with adjustment for study-site as well as age, sex, and race/ethnicity. Compared to controls, TMD cases reported more trauma, greater parafunction, more headaches and other pain disorders, more functional limitation in using the jaw, more nonpain symptoms in the facial area, more temporomandibular joint noises and jaw locking, more neural or sensory medical conditions, and worse overall medical status. They also exhibited on examination reduced jaw mobility, more joint noises, and a greater number of painful masticatory, cervical, and body muscles upon palpation. The results indicated that TMD cases differ substantially from controls across almost all variables assessed. Future analyses of followup data will determine whether these clinical characteristics predict increased risk for developing first-onset pain-related TMD

Objective. The aim of this study was to present epidemiological parameters of caries prevalence in children and adolescents in index age groups on a national and regional level in Bosnia and Herzegovina (BH). Materials and methods. The study was conducted during 2004 year for children aged 6 and 12, and during 2007 for adolescents aged 15. An oral health survey was performed on a total number of 1,240 children and adolescents in line with World Health Organization methodology and criteria. Results for caries prevalence and treatment needs were presented and discussed in this paper. Results. Mean dmft (decay, missing, filled teeth for primary dentition) for children aged six was 6.7 (SD±3.9) in that the decayed teeth constituted the major part of the index (88.8%), followed by extracted teeth (8.9%) and a small percentage of filled teeth (2.3%). In 12-year-olds DMFT (Decay, Missing, Filled Teeth for permanent dentition) was 4.2 (SD±2.9), Significant Caries index (SiC) was 7.7 (SD±2.9), the decayed teeth constituted the major part of the index (45.4%), followed by 42.1% of FT and 12.5% of extracted teeth. Among 15-year-olds the DMFT was 7.6 (SD±4.1), SiC was 9.2 (SD±1.2), and filled teeth constituted the major part of the index. Conclusion. The present study provides some evidence of relatively high caries prevalence and severity in comparison with Western European countries. It is necessary to devote more attention to the oral health of children and adolescents. Community based oral health promotion, preventive programs and preventive oriented public dental health care services should be made available and accessible to all children in Bosnia and Herzegovina.

Background: At present, there is no evidence on whether using condition-specific Oral Health-Related Quality of Life (OHRQoL) measures provides more reliable information than generic measures for needs assessment. Therefore, the objective was to assess the discriminative ability of one generic and one condition-specific OHRQoL measure, namely, respectively, the short form of the Oral Health Impact Profile (OHIP-14) and the Condition-Specific form of the Oral Impacts on Daily Performances (CS-OIDP) attributed to malocclusion, between adolescents with and without normative need for orthodontic treatment.

The Sport Motivation Scale was firstly developed in French and later translated into English and validated by Pelletier et al. (1995). It is based on the principles of self-determination theory. The present study translated the English version into Portuguese to access and validate it with Brazilian athletes using a sample of 419 athletes (127 women and 292 men) from ten sports. The Brazilian version of the scale showed satisfactory levels of internal consistency and temporal stability over a four-week period. The results of a confirmatory factor analysis partially supported the seven-factor structure. Finally, gender differences were found in all subscales. Taken together, these findings support the use of the Brazilian version of the scale for the assessment of motivation in sport.

The study aim was to identify predictors of impaired oral health-related quality of life (OHRQoL). Employees of five companies were offered a clinical full-mouth examination. Oral health-related quality of life was measured with the German version of the Oral Health Impact Profile (OHIP) and summarized as additive scores (OHIP-ADD) and as prevalence of negative impacts (OHIP-SC). Two logistic regression models were developed for the odds of increased scores of the target variables OHIP-ADD and OHIP-SC. The target variables were dichotomized, and for the OHIP-ADD, the cut-off point for having impaired OHRQoL was heuristically defined as OHIP-ADD > 34. For the OHIP-SC, the corresponding threshold was OHIP-SC > 0. In the model for the OHIP-ADD, female gender, impaired aesthetics, few posterior occluding pairs, and painful masticatory muscles proved to be significant independent variables. For the OHIP-SC, female gender, impaired aesthetics, painful masticatory muscles, joint sounds, missing mandibular teeth, and carious teeth were significant. This cross-sectional study showed that within the models for both OHIP-ADD and OHIP-SC the high-risk person for impaired OHRQoL is a woman with impaired aesthetics and painful masticatory muscles.

To contrast the sensitivity, specificity, and positive–negative predictive values between dental fluorosis prevalence scored on 28 (DF28) and on six permanent teeth (DF6), we undertook a cross-sectional study on 1,538 adolescents (12 and 15 years old) residing in Hidalgo State, Mexico, a naturally fluoridated (>0.7 ppm) area at an elevated altitude (>2,500 m above sea level). Dental fluorosis was scored using Deans modified index. Using the scores obtained for all teeth present (DF28) as a gold standard, we calculated the sensitivity, specificity, positive–negative predictive values, and receiver operating characteristic and concordance index pertaining to the scores based on six teeth (upper incisors and canines). DF28 fluorosis prevalence was 81.7%; based on DF6, it was 58.7% (23% difference). Among 12 year olds, the difference between DF28 and DF6 was 20.1% (84.5 vs. 64.4%); among 15 year olds, it was 25.4% (79.4 vs. 54%). Among girls, it was 23.2% (81.1 vs. 57.9%) and among boys, 22.8% (82.2 vs. 59.4%). The fluorosis community indices were 1.75 (DF28) and 1.11 (DF6). All positive predictive values reached 100% while negative predictive values were below 45%. Concordance between DF28 and DF6 was 53.9%, and kappa coefficient was 0.40. Partial scoring of fluorosis based on esthetically important permanent teeth underestimated prevalence, compared to full-mouth scoring. The decision to use an abridged Dean’s index protocol must take into account the number of teeth examined, and which specific teeth are examined, to appraise the benefit of reduced data collection effort against possible information loss.

Background: This article reviews the caries profile for children in Nigeria and proposes an appropriate framework for addressing the silent caries epidemic. Discussion: We reviewed the caries prevalence among children in Nigeria, assessed the existing responses to the caries epidemic including the national oral healthcare delivery situation in the country and discussed the current caries management in children. We then proposed a response framework for Nigeria. We argue that successful interventions will require the adoption of a socio-ecological model. This would ensure that the micro-, meso-, exo-and macrosystems required to support the behavioural, structural and biological interventions for promoting caries prevention are addressed. National oral health surveys are required to help understand the epidemiology, social determinants of and factors that undermine the ability of children to access oral health care. A global caries prevention agenda for children would help get the government's support for a national response agenda. Currently, there is no global call for action on the caries epidemic in children. This lack of an agenda needs to be urgently addressed. Summary: A combination of approaches for the prevention of caries in children in Nigeria is needed. A national survey is needed to generate the needed evidence for the planning of community relevant responses to the national caries epidemic in children. The design of a global health agenda for children is an important first step that can facilitate the development of a national oral health programme for children in Nigeria.

Objectives: To examine the relations between density of dental practitioners (DDP) and socio-economic and demographic factors shown to affect access to dental care for the elderly. Methods: Data are taken from a cross-sectional survey -2008 Disability Healthcare -Household section Survey (HSM). HSM is a representative random sample of French people living in their own domiciles. Our study focuses on the 9233 individuals aged 60 years and above. Multilevel models are employed to disentangle the relations between the determinants of dental care utilisation and DDP. Statistical analyses are conducted using SAS 9.2 and HLM 6. Results: Low-income and lack of complementary health insurance are associated with higher odds of not having visited a dentist, revealing a high unequal access to dental care. By using multilevel modelling, DDP appears to be a significant factor to access to dental services. When considering the intricate relations between income gradient and DDP, the latter lessens the income-related inequality to access dental services. Conclusion: DDP seems favouring a more equitable access to dental care, mitigating undercaring of the poorest. This point is to be added in the debate about density of healthcare suppliers.
