Background: Although type 1 diabetes mellitus (T1DM) has a significant impact on oral health, its association with dental caries is yet not clear. Aim: The aim of this study was to evaluate the salivary flow rate and caries in Brazilian youth with type 1 diabetes mellitus. Setting and Design: A Cross-sectional study was performed in a tertiary university hospital. Materials and Methods: Fifty-one age matched subjects suffering from type 1 diabetes mellitus were selected for the study and evaluated for the following: salivary flow rate, number of decayed, missing and filled tooth in permanent dentition (DMF-T) and decayed, extracted, filled tooth index in the deciduous dentition (def-t); visible plaque index (VPI) and gingival bleeding index (GBI). Statistics and analysis: The t test was utilized when the variables showed normal distribution. The Mann-Whitney test was utilized for comparing non-normal variables. Kolmorgorov-Smirnov test was used to assess the normality assumption. The differences were considered significant when P < 0.05. Results: The age and gender distribution of patients and controls was 11.3 ± 3.4 years (56% males) and 11.9 ± 3.4 years (37% males). The mean glycated hemoglobin value in the diabetics was 9.7 ± 1.9%. Salivary flow rate was lower in the diabetic pateints as compared to controls (P = 0.02). No differences were found in the DMF-T/def-t indices of diabetic and non-diabetic patients (P = 0.43/0.14). VPI was similar in both the groups (P = 0.15). GBI was higher in the diabetics (8.1 vs. 5.18; P = 0.11). There were no differences in the dental caries experience and dental plaque in the two groups. Conclusion: The lower salivary flow rate in diabetics could have been related to their higher GBI. The higher GBI in the diabetics is a matter of concern in the diabetics and is a sign for higher chances of developing periodontal problems.
