Bez obzira na napredak dentalne medicine i poboljšanje životnih uvjeta, bolesti usne šupljine, posebice karijes, i dalje uzrokuju ozbiljne probleme i disfunkciju stomatognatoga sustava, što utječe na cijeli organizam i kvalitetu života (2). Zubni karijes kronična je bolest, a nastaje kao posljedica interakcije domaćina, patogena, okoliša i vremena (3). Morfologija zuba, sastav sline, učestali obroci, neodgovarajuća prehrana te loša oralna higijena potiču nastanak karijesne lezije (3). Od 80 do 90 % svih karijesnih lezija lokalizirano je okluzalno, u fisurnom sustavu (4, 5). Naime, u dubokim i uskim brazdama žvačnih ploha zaostaju ostatci hrane, slina i mikroorganizmi koji stvaraju biofilm-kompleksnu strukturu koja im je hranjivi supstrat, ali i zaštita od vanjskih utjecaja (5).

El Bosque funded the design and development of the e-learnings, and UNICA leader researchers meeting time with centres. Other leader universities (KCL, U. of Leeds and U. of Sheffield) funded their researchers' contribution time. The study received a grant from IADR Regional Development Program Latin American Region (IADR RDP LAR) to promote research in Latin American countries (13 centres). The Alliance for a Cavity-Free Future Colombian Chapter (ACFF CC) funded partially the elearnings and the printing of the didactic aids. The Global Collaboratory for Caries Management (GCCM) uploaded the e-learnings in the CCI website. The 20 dental schools (universities) and 1 health provider funded each centre study setting and development. CariesCare International (CCI) is a health outcomes-focused, patient-centred, risk-based caries management system (2019). UNICA, with KCL and the University of Leeds, designed a 1-year schoolchildren-multicentre RCT to assess its caries-progression-control effectiveness. Twenty-one centres in 13 countries joined. UEB-IRB: Feb-2020. Aim: this report aims at describing the study's cariology-related education strategies including pandemic-era adaptations. Methods: cariology-education strategies: training centres' dentists in CCI through the CCI oral-health record (OHR), an e-learning and a workshop. After the pandemic initiated, UNICA shifted to a multicentre single-group children-interventional study with pandemicadapted CCI (non-aerosol generating procedures-non-AGP and remote consultation), plus a CCI short toothbrushing/dietary habits behaviour-change tool (SBCT) (COM-B model). All agreed (UEB-IRB: July-2020). An additional 1-module non-AGP CCI-4D e-learning was planned. Results: Oral-health record: a CCI 4D-cycle pandemic-adapted OHR in Excel and a WHO-guided daily-sugar food/beverage-consumption pictures diagram were designed. SBCT: a 6-item behaviour-assessment form and six children-/parent-motivation didactic aids and self-assessment forms were designed. CCI pandemic-adapted centres' workshop: two 4-hour workshops were conducted (Nov-2020) with coordinators/practitioners (English: n=16; Spanish: n=43). CCI 4D-cycle implementation e-learning: 5-module English/Spanish-language e-learnings were designed (duration time: 39'4'' and 39'8'', respectively) with QR docs.google.com quizzes and uploaded to CCI's webpage (GCCM:

This study aimed to assess whether parental dental anxiety and knowledge of caries preventive measures are associated with their psychological profiles and their children's oral health. Methods: This case-control study involved parents, who were divided according to whether their children did or did not have active caries. The differences in Short version of the Dental Anxiety Inventory, and Knowledge of Caries Preventive Measures (KCPM) scores between the parents whose children have and do not have active caries was established by the Mann-Whitney U test (P < 0.05). Conclusion: Parental dental anxiety and knowledge of caries preventive measures are associated with the oral health of their children.

It was also the aim to establish level of agreement between students, dentists and children in their assessment of child's behaviour. Methods. Assessment of dental anxiety in dental office was carried out in the sample of 63 child patients (33 boys, and 30 girls). The age of patients ranged from 3 to 16 years (mean = 7.16 years). Child's behaviour ratings before and after treatment were obtained from dental students, specialists of paediatric dentistry and children in the dental chair. The child's behaviour was assessed using Frankl's Rating Scale, Wright’s Rating Scale, and Facial Image Scale (FIS). The Crombach’s alpha was calculated to establish internal reliability of the scales. Results. The correlation coefficients between scores obtained by students, doctors, and children were calculated to establish validity of scales. There was a high agreement on the FIS after treatment between ratings from the doctors and students (r = 0.754 ; P < 0.01). Child’s ratings on the FIS after treatment showed a high correlations with ratings from students and doctors (r = 0.713 ; P < 0.01 ; and r = 0.682 ; P < 0.01, respectively). Conclusion. High value of Crombach’s alpha (α = 0.8528) allow conclusion that three rating scales provide highly reliable assessment of child behaviour in dental office. FIS scale should be regarded as suitable and reliable instrument for measuring child dental anxiety.

Five different composites were used (Evetric, GrandioSO, Admira Fusion, Filtek Z550, Dynamic Plus). The gloss of the tested material was measured with a glossmeter before and after chemical degradation in different acidic beverages. Statistical analysis was performed using a t-test for dependent samples, ANOVA, and a post hoc test. For comparison between groups, a level of significance was set at 0.05. Initial gloss values ranged from 51 to 93 at baseline to 32 to 81 after chemical degradation. The highest values were obtained for Dynamic Plus (93.5 GU) and GrandioSO (77.8 GU), followed by Admira Fusion (82 GU) and Filtek Z550 (70.5 GU). Evetric showed the lowest initial gloss values. After acidic exposures, the gloss measurements revealed different patterns of surface degradation. The results showed that the gloss of the samples decreased ...

This study aimed to evaluate Croatian pediatricians’ knowledge and practice regarding dental injuries management and the use of mouthguards as means of protection against traumatic injuries. Materials and methods: A questionnaire-based cross-sectional survey conducted among 186 pediatricians examined their demographic characteristics, knowledge and experience with dental injuries. Student t-test or one-way ANOVA, with Tukey’s post-hoc were used to analyze obtained data (p ≤ 0.05). Results: The overall mean score of knowledge on the management of dental injuries was 3.6 ± 1.53 points. Male pediatricians (p = 0.016), those who witnessed dental injuries (p = 0.003), and those who had more than ten years of pediatric practice (p = 0.027) showed better knowledge. The results of multiple linear regression analysis demonstrated impact between pediatricians’ knowledge in the emergency treatme...

It is necessary to determine the degree of acceptance of treatment. This study includes an evaluation of the Index of Orthodontic Treatment Need (IOTN) according to the Aesthetic Component (AC) of dental health in schoolchildren. METHODS The research included 300 schoolchildren (150 girls, 150 boys) with an age range from 12 to 15 years. An evaluation of the need for orthodontic treatment according to the AC consisted of a ten-grade scale illustrated with a sequence of ten intraoral photographs showing different degrees of acceptability of dental appearance. Results were expressed as absolute and relative frequencies. The Chi-square test (in the absence of the expected frequencies of Fisher's Exact test) was used for testing the significance of differences. Cohen's kappa statistic measure was used for measuring the agreement be...

The study was performed in a sample of 138 pairs of mothers and their children aged 11-12 years. Corah's Dental Anxiety Scale (CDAS) was used to assess degree of anxiety in children and their mothers. DMFT scores, as a measure of dental health, were collected for all children under study. Spearman's rank correlation coefficients (r) were computed to compare degree of association between analysed parameters. The patients were classified in the following groups: 1. low dental anxiety (CDAS = 4-8; N=53), 2. moderate dental anxiety (CDAS = 9-12; N = 45), and 3. high dental anxiety (CDAS = 13-20; N = 40). All children were divided into four groups on the basis of DMFT: caries-free children: DMFT = 0; low caries intensity: DMFT = 1-2; moderate caries intensity: DMFT = 3-4; and...

Stakleno-ionomerni cementi su materijali izbora koji se primjenjuju uvijek kada je otežano postizanje suhog radnog polja. Indicirani su u male djece, visokorizicne za razvoj karijesa, a posebice u pacijenata s posebnim po- trebama i u kojih je otežano stomatolosko lijecenje. Kemijska veza s caklinom temelji se na interakciji karboksilnih skupina poliakrilne kiseline i kalcij-hidroksilapatita iz cakline. Zbog mogucnosti konti- nuiranog otpustanja fluorida te akumuliranja fluorida, stakleno-ionomerni cementi imaju i određeno preventivno djelovanje
