RESUMEN
OBJECTIVES: To determine whether positive self-perceived oral health is associated with sociodemographic health variables, with an emphasis on resilience, in community-dwelling older adults in southern Brazil. DESIGN: Cross-sectional study nested within a cohort study. SETTING: Carlos Barbosa in southern Brazil. PARTICIPANTS: Four hundred ninety-six community-dwelling adults aged 64 and older. MEASUREMENTS: Sociodemographic information, a health history, and health perceptions were assessed using a structured questionnaire. Resilience was assessed using a resilience scale. For each participant, a brief oral examination was performed to assess number of teeth. Positive self-perceived oral health was the outcome of interest. RESULTS: A final, fully adjusted Poisson regression model showed that high resilience potential (prevalence ratio (PR)=1.18, 95% confidence interval (CI)=1.06-1.32), income (PR=1.18, 95% CI=1.07-1.30), and no reported change in diet because of dental problems (PR=1.34, 95% CI=1.13-1.60) were associated with positive self-perceived oral health. Participants living in rural areas were less likely to report positive self-perceived oral health (PR=0.83, 95% CI=0.75-0.93). CONCLUSION: 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.

Mandibular advancement (MA) by means of functional orthopedic techniques is currently used in young patients to stimulate mandibular growth. The aim of this study was to evaluate the morphological changes in the mandibles of 2-, 7-, and 16-month-old female mice after MA. Every 3 days during 1 month, the lower incisors were trimmed by 1mm to induce protrusion when the animal was feeding. The left mandibles of the 30 experimental and 28 control individuals were subsequently dissected and digital images were obtained to analyze nine linear/angular measurements. The condylar microstructure was also analyzed by scanning electron microscopy (SEM). The linear/angular measurements showed a growth response in different mandibular regions in 2- and 16-month-old individuals. SEM showed that, in the 7-month-old mice, the condylar cartilage had regenerated in the treated individuals but not in the controls. The results suggest that MA produces mandibular growth in 2- and 16-month-old female mice. Although there was no mandibular growth in 7-month-old mice, regeneration of the condylar cartilage was detected, thus demonstrating that different responses to the MA stimulus occur in female mice of different ages.
