This fact makes it crucial to identify factors that increase the risk of cognitive decline in the population. Evidence suggests that poor periodontal health may be one of those factors; nonetheless, to ascertain this possibility, it is necessary to account for the influence of education, as it is frequently the determining factor that explains the association between a risk factor and cognitive impairment. Therefore, this study aimed to determine whether poor periodontal health is associated with impaired cognitive performance in older people from an agricultural community in Chile, independent of education. Methods A cross-sectional study was conducted with the entire universe of participants older than 60 years from the MAUCO cohort in 2015. The exposure of interest was periodontal health status assessed through a proxy measure based on gum appearance (color) and b...

Methods: A prospective cohort design was adopted based on the FIBRA study database (Fragility in Brazilian Elderly), with a baseline performed in 2008-2009 and follow-up in 2016-2018, elapsed on average 100.2 ± 9.2 months. The outcome variable was the incidence of frailty. The exposure variable was masticatory function according to edentulism and self-reported chewing difficulty. Adjustment variables were sociodemographic, behavioral, and general health conditions. A Poisson regression model with robust variance was used to estimate the relative risk. Results: the cumulative incidence of frailty over eight years was 30 cases per 100 edentulous participants with chewing difficulties, who had a higher risk of developing frailty (RR: 1.75 95% CI 1.09-2.81) than the dentate elderly without chewing difficulties, regardless of smoking (RR: 1.71 95% CI 1.07-2.73) and socioeconomic status (RR: 1.72 95% CI 1.13-2.62). Conclusion: Loss of masticatory function increases the risk of frailty in older people. Future research should study whether the rehabilitation of oral function reduces this risk.

This approach has been little explored in the literature, especially when considering the older age group. Aim: The aim of this study is to evaluate the factors associated with three distinct functional dentition classification. Methods: Crosssectional exploratory study using secondary data from the Frailty in Older Brazilians (FIBRA) Project of 876 older adults living in Campinas, Brazil. The indicators of dental function assessed was number of natural teeth present, occluding pairs of teeth and the Eichner index, which were verified by trained dentists, following the World Health Organization criteria for epidemiological studies in oral health. The explanatory variable assessed was the selfperception of oral health-related quality of life measured by the Geriatric Oral...

Methods: A Cross-sectional study was conducted with 647 older people from the community, without cognitive deficit, living in Campinas, Brazil. A self-report questionnaire assessing the presence or absence of teeth (edentulism) and use of complete denture was applied, identifying the location of the denture, whether in the upper and/or lower arch. In the same session oral clinical exams were performed, considered the gold standard. The self-report validation was performed by calculating sensitivity, specificity, predictive values, odds ratios and Kappa agreement. Results: There were high percentages of sensitivity (95–99%), specificity (84–97%), positive (81–97%) and negative (95–98%) predictive values, obtaining an elevated level of confidence and quality intrinsic value of self-report. Agreement with the clinical examination was excellent for all vari...

Ageing (biological) is characterized by a progressive loss of physiological integrity, leading to functional changes and an increased vulnerability to death 1. These progressive changes can be observed in the oral mucosa. The aim of this letter-dedicated to geriatric dentistry and specialists in oral medicine-is to summarize the effects of aging in soft oral tissues. The oral mucosa of elderly persons may not be distinguishable from that in young patients. Nevertheless, the continuing trauma (e.g., cheek biting), mucosal manifestations of autoimmune skin diseases, habits (e.g., smoking) and hypofunction of the salivary glands can alter the appearance and character of the oral tissues in elderly persons 2. In the epithelium, the major changes recorded are the presence of less prominent epithelial ridges, epithelial atrophy and a reduction of the cellular density and mitotic activity 3. Along with this, there is a loss of elastin and adipose tissue in the submucosa and an increase in fibrous connective tissue with a degenerative change in the collagen. All this can result in the slowing of tissue regeneration, which should be taken into consideration when installing dental implants. Normal ageing causes a loss of sense of taste due to changes in the membranes of the gustatory cells, which alter the function of ionic canals and receptors 4. Clinically, the histological changes may be accompanied by dry thin smooth oral mucosal surfaces, with a loss of elasticity and a characteristic stippling. These changes could predispose the oral territories to trauma and infection, particularly when the patients are using dental prosthesis or are afflicted by disturbances in salivary function (e.g., chronic hyposialia) 5. Ectopic sebaceous glands (Fordyce spots) in the lips and cheeks can also increase with advancing age. Dorsum of the tongue shows a decrease in the filiform papillae, which gives it a smooth and shiny appearance 6. This appearance could be exacerbated by the deficit of iron or B complex vitamins. The ventral zone of the tongue develops sublingual varicosities, which are considered variations from normal 7. Recently we carried out a systematic review of literature to identify major lesions of the oral mucosa in older persons. The data received from thirteen countries showed that some of the more relevant diagnosis in elderly persons are denture-related stomatitis, epulis fissuratum, traumatic ulcers, irritation fibroma, recurring aphthous stomatitis, fissured tongue, hemangioma, melanin pigmentations and oral lichen planus 8 .

Oral mucosal lesions and normal variations of oral anatomy (OMLs) are very common in this people, but few studies have examined the frequency and prevalence of these conditions worldwide and less in Chile. The aim of this research was to evaluate the frequency of OMLs in a Chilean elderly population. It was conducted a retrospective study (Talca, Chile). Two hundred seventy-seven OMLs were classified in groups and anatomical sites. In order to contextualize our numbers, we made a systematic review using Publish or Perish software, Google Scholar and InteractiVenn. The most prevalent OMLs groups were soft tissue tumors, epithelial pathology, facial pain and neuromuscular diseases, and dermatologic diseases. The most frequent OMLs included irritation fibroma (30 patients, 10.8%), hemangioma (20, 7.2%), burning mouth syndrome (20 cases, 7.2%), oral lichen planus (12, 4.3%) and epulis fiss...

La paciente relata prurito y sensación urente con hiperestesia en el área. No hay compromiso del estado general. Descartada una reacción alérgica y angioedema, el diagnóstico fue una úlcera traumática, como resultado de una mordida posterior a la anestesia del nervio alveolar inferior. El tratamiento consistió en ibuprofeno (suspensión oral, 200 mg / 5 ml, en dosis de 10mg / kg cada 8 horas por 5 días) y control clínico cada dos días (primer control, B). La resolución definitiva ocurrió 10días después de la primera atención. Con el fin de prevenir lesiones de los tejidos blandos, el odontólogo debe indicara los padres y cuidadores la importancia del monitoreo del niño por varias horas, luego de la atención odontológica que implique procedimientos con anestesia local por bloqueo troncular (nervio alveolar inferior), recordando que es más seguro para el paciente comer luego de que el efecto del anestésico desaparece

A 6-year-old girl presented to the dental clinic 24 hours after a previous dental visit, exhibiting a white-yellowish lesion on the lower lip with areas of ulceration covered by fibrin (A). The patient reported itching and a burning sensation with hyperesthesia in the affected area. There were no systemic complications. Allergic reaction and angioedema were ruled out, and the diagnosis was a traumatic ulcer resulting from biting after inferior alveolar nerve anesthesia. The treatment consisted of ibuprofen (oral suspension, 200 mg/5 ml, at a dose of 10 mg/kg every 8 hours for 5 days) and clinical follow-up every two days (first follow-up, B). Complete resolution occurred 10 days after the initial visit. To prevent soft tissue injuries, the dentist should instruct parents and caregivers on the importance of monitoring the child for several hours after dental procedures involving local anesthesia by nerve block (inferior alveolar nerve), emphasizing that it is safer for the patient to eat after the anesthetic effect has subsided.
