In a previous clinical study regarding the incidence of caries and the periodontal health, a group of young patients with various levels of glyco-metabolic control was studied and the results showed that the decayed-missing-filled teeth (DMFT) index was higher in insulin dependent diabetes mellitus (IDDM) type 1 patients with a poor glyco-metabolic balance than in a control group or in IDDM patients with sufficient glyco-metabolic balance. In light of these results, the purpose of this study was to find an explanation for these clinical observations by searching at a microbiological level. The results indicate that salivary counts of Streptococcus mutans and lactobacilli were higher in patients with active caries whether or not they be diabetic, than in people with no active caries, but the count of S. mutans was not directly correlated to the DMFT index. No significant alterations were found in salivary flow, pH, buffer capacity and glucose concentration in all the groups in this study. We conclude that the salivary count of S. mutans is not sufficient alone to account for the higher susceptibility to active caries of young IDDM patients with poor glyco-metabolic control.

Abstract

In a previous clinical study regarding the incidence of caries and the periodontal health, a group of young patients with various levels of glyco-metabolic control was studied and the results showed that the decayed-missing-filled teeth (DMFT) index was higher in insulin dependent diabetes mellitus (IDDM) type 1 patients with a poor glyco-metabolic balance than in a control group or in IDDM patients with sufficient glyco-metabolic balance. In light of these results, the purpose of this study was to find an explanation for these clinical observations by searching at a microbiological level. The results indicate that salivary counts of Streptococcus mutans and lactobacilli were higher in patients with active caries whether or not they be diabetic, than in people with no active caries, but the count of S. mutans was not directly correlated to the DMFT index. No significant alterations were found in salivary flow, pH, buffer capacity and glucose concentration in all the groups in this study. We conclude that the salivary count of S. mutans is not sufficient alone to account for the higher susceptibility to active caries of young IDDM patients with poor glyco-metabolic control.
