RESUMO
INTRODUCTION: Diabetes mellitus (DM) is a risk factor for periodontitis for over 40 years and novel evidence suggests that periodontitis has an impact on glycemic control in patients with diabetes. This study aimed to compare oral health complications in diabetic older patients from Brazil and France. METHODS: This cross-sectional study included 120 patients aged 65 and over diagnosed with type 2 diabetes. Sixty patients were admitted to a center for diabetes and hypertension care in Brazil and 60 patients were admitted to the Rouen University hospital. Dental conditions were assessed through the decayed, missing and filled teeth index and periodontal condition was assessed using the Community Periodontal Index. The significance threshold was pâ¯<â¯0.05. RESULTS: Decayed teeth differed statistically between the groups (pâ¯=â¯0.001). The French group presented more tooth mobility, gingival recession and furcation involvement (pâ¯<â¯0.001). Tooth brushing frequency differed significantly between the groups (pâ¯<â¯0.030). The main cause of missing teeth was periodontitis in the French group and caries and periodontitis in the Brazilian group (pâ¯<â¯0.001). Statistical significance was found for use of fixed upper (pâ¯=â¯0.013) and lower (pâ¯=â¯0.013) dentures in the French group. The French group needed upper denture rehabilitation (pâ¯=â¯0.010) while the Brazilian group needed lower denture rehabilitation (pâ¯=â¯0.003). CONCLUSION: Edentulism was prevalent in diabetic older people in both countries. However, the French participants presented with better oral health.
