RESUMO
Objective: To evaluate the oral health status in children with type 1 diabetes mellitus. Material and Methods: Dental examinations, based on World Health Organization caries diagnostic criteria for DMFT index for permanent dentition and survey were performed among 160 children, aged 10-15-year-old, divided into two groups. The first group consisted of 80 children with type 1 diabetes mellitus (41 females, 39 males), and in the second group, consisted 80 healthy children (49 females, 31 males). Frequency, odds ratio and Mann-Whitney U test were used in the statistical analyses. The level of significance was set at 5%. Results: The higher mean of the DMFT index was found among children with type 1 diabetes compared to the healthy group. The mean DMFT index for diabetic children was 6.56 ± 3.56 and for the healthy group was 4.21 ± 2.63. Moreover, the frequency of decayed teeth was higher in children with type 1 diabetes than in the healthy group. The higher risk of caries was found in diabetic children compared with healthy for 1.35 times. A higher proportion of children, 61.25% with type 1 diabetes mellitus, reported that they brush their teeth once per day, 22.50% twice per day, and 16.25% rarely. From the healthy group, 46.25% of children brush their teeth once per day, and 42.50% twice per day and 11.25% rarely brush their teeth per day. Conclusion: Diabetic children are at higher risk for caries than are healthy children.
