RESUMEN
AIM: To investigate the oral health of children and adolescents with type 1 diabetes (T1D) and its associations with diabetes-related and lifestyle factors. DESIGN: Cross-sectional study at a large tertiary hospital pediatric diabetes clinic. Oral examination determined dental caries experience and gingival health. Secondary outcome measures included salivary characteristics, oral hygiene and dietary practices, and diabetes-related factors. RESULTS: Eighty children and adolescents with T1D participated; mean (SD) age and HbA1c were 13.4(2.6) years and 7.7(0.9)%, respectively. Forty-seven (59%) participants had one or more decayed, missing or filled teeth; 75 (94%) participants had gingivitis. Half (50%) reported ≥3 hypoglycemic episodes necessitating rapid-acting carbohydrate in the previous week. Sixty-two participants (78%) had normal saliva flow, however, 42 (52%) had reduced salivary buffering capacity. Glycemic control (HbA1c ) was not associated with caries experience, gingival health or salivary characteristics. Increased frequency of tooth brushing (OR, 0.11; 95%CI 0.01-0.97, p = 0.05) and interdental flossing (OR, 0.31; 95%CI 0.12-0.81, p = 0.02) were associated with lower caries experience. Interdental flossing (OR, 0.31; 95% CI 0.12-0.80, p = 0.02) and good oral hygiene (OR, 0.06; 95% CI 0.01-0.22, p < 0.001) were associated with less gingivitis. CONCLUSION: Poor oral health is common in children with T1D, regardless of HbA1c. Given potential implications for short- and long-term systemic health, this study demonstrates the need for targeted strategies to improve oral health in children with T1D.
