Relationship between tooth loss, nutritional status and consumption of macro and micronutrients in elderly people from southern Brazil

Maintaining a functional natural dentition plays an important role in keeping a satisfactory nutritional status. The aim of this study was to evaluate the relationship between oral health conditions determined by the presence of edentulism and the number of missing teeth, nutritional status and consumption of nutrients by the elderly. This cross-sectional study comprised 494 independent elderly of both genders, over 60 years of age, registered at the Brazilian public health service in Londrina, southern Brazil. The data collection included: oral examinations; anthropometric measurements by calculating the Body Mass Index (BMI); analysis of food consumption based on a multiple pass 24-hour dietary recall and a food intake frequency questionnaire; and structured interviews to obtain sociodemographic information. Multiple linear regression, the Fisher's Exact test, chi-square and Mann-Whitney tests, were applied at a 5% significance level. The prevalence of edentulism was 47.3%; this predominated in females, age group from 65 to 74 years, low education level and low/medium economic classification. A larger numberof underweight and fewer number of overweight elderly were recorded among the edentulous versus dentate participants (< 0.0001). Significantly lower consumption of several nutrients, as well as fruit, was recorded among the edentulous group. In particular, carbohydrates, vitamins (B1, B9 and C), and the majority of the minerals studied were associated with a larger number of missing teeth. In conclusion, tooth loss was associated with the food consumption pattern of some macro-and micronutrients and the nutritional status of the Brazilian elderly.

Do Parents' Oral Health Literacy Levels Influence Their Response to Interventions to Improve Their Knowledge of Traumatic Dental Injuries?

Abstract Objective: To measure the influence of oral health literacy (OHL) level in the improvement of knowledge about traumatic dental injuries (TDI) after an educational intervention. Material and Methods: A total of 257 parents of children aged 0-12 years had their OHL level evaluated (BREALD-30). A leaflet with information about how to respond to TDI Emergency was developed and delivered to the parents. A questionnaire about attitudes towards TDI was administered before (TDIQ1) and after (TDIQ2) parents read the educational leaflet. The hypotheses were evaluated by non-parametric tests, correlation analysis and logistic regression. Results: The mean OHL score was 21.6. The means of correct answers in TDIQ1 were 5.5 and 5.9 (p = 0.066) and in TDIQ2 were 6.6 and 7.7 (p=0.003) between the groups with inadequate and marginal/adequate OHL, respectively. In the logistic regression, the total score of BREALD-30 and the maximum number of correct answers in TDIQ2 maintained statistical association when adjusted for schooling, gender, age of the parents, family income and the number of correct answers in the first application of the questionnaire. Conclusion: The level of OHL influenced the improvement of parents' knowledge about emergency care in cases of TDI in children from an educational intervention using a leaflet, and this intervention was more effective for parents with adequate OHL.
