Using a hierarchical approach, positive self-perceived oral health was found to be associated with several variables included in the conceptual framework of oral health outcomes, such as resilience. Resilience may act as a potentiating agent in the positive adaptation to tooth loss.

Interventions aiming to reduce tooth loss and edentulism in the elderly should account for social and environmental factors, in combination with clinical and behavioural components.

There is evidence suggesting that edentulous older persons modify their diet, avoiding foods that are difficult to chew, such as fruit and vegetables; meanwhile, the consumption of these foods is associated with prevention of chronic diseases. However, few studies evaluated whether a poor oral status without prosthetic rehabilitation is associated with a reduction in the consumption of fruit and vegetables in community-dwelling older persons. We evaluated the association of oral status with emphasis on complete dentures use with the daily consumption of at least 400 g of fruit and vegetables, following the recommendations of the WHO. A random sample of 282 south Brazilians ≥60 years of age was evaluated. Measurements included a questionnaire to assess sociodemographic, behaviour, and health data; consume of fruit and vegetables by means of a 24-h diet recall, and oral status assessment, by means of oral examinations assessing the number of teeth and use of dental prosthesis. Multivariate Poisson regression showed that the only variable significantly associated with inadequate consumption of fruit and vegetables was edentulism with the use of only one denture [PR=1·75 (1·11-2·74)]. Edentulous participants wearing only one denture were less likely to consume at least 400 g day(-1) of fruit and vegetables. These results indicate that, in edentulous community-dwelling elderly, oral health rehabilitation might play an important role in the maintenance of consumption of adequate amounts of fruit and vegetables, which is an important component of a healthy diet and also in the prevention of chronic diseases.

Association between number of teeth, edentulism and use of dentures with percentage body fat in south Brazilian community-dwelling older people Objective: To evaluate if poor oral status was associated with percentage body fat in a representative sample of south Brazilian community-dwelling elderly. Background: Evidence suggests that elders with extensive tooth loss and edentulism present with compromised chewing function, which results in dietary changes. However, few studies have assessed whether poor oral status is associated with percentage body fat in community-dwelling elderly. Materials and methods: A random sample of 471 south Brazilians =>60 years of age was evaluated. Measurements included a questionnaire to assess socio-demographic, behavioural, general, and oral health data. Percentage body fat was measured with a Tanita TBF 612 digital scale, which measures foot-to-foot bioelectrical impedance; and oral status assessment, by means of oral examinations assessing the number of teeth and use of dental prostheses. Correlates of risk of inadequate percentage body fat were assessed by means of multinomial logistic regression. Results: Edentulous participants were more likely to be underfat Conclusion: The present study shows that edentulous older people had higher odds for inadequate percentage body fat. The maintenance of teeth had a crucial role in increasing the chance of having an adequate body fat percentage in the study population.

Maintaining a good salivary function may be essential for the prevention of the incidence of edentulism in this age group. Furthermore, our findings suggest that rehabilitations with partial removable dentures may be detrimental to long-term oral health.

There is a need for the development of national surveys and standardised tools for the assessment of oral health in older adults. Also, intense advocacy to modify and influence public health policies in the different countries of the LAC is strongly recommended.
