Abstract

The relationship between diabetes mellitus and dental caries, particularly among adults has received far less attention. However, a consistent relationship between diabetes mellitus, dental caries and salivary pH is lacking. Therefore, the correlation between salivary pH and caries prevalence in non-diabetics and diabetics was evaluated.Fasting blood glucose level and salivary pH for each subject were measured and caries index was recorded as DMFT index. The results show that a decreased salivary pH and an increased incidence of dental caries in subjects with uncontrolled diabetes as compared to control group and those with controlled diabetes. Decreased salivary pH and increased dental caries rate was observed in subjects with controlled diabetes as compared to control group. Thus, diabetes mellitus may have a direct effect on salivary pH, reducing it from normal levels irrespective of diet.
