Correlation of Salivary pH, Incidence of Dental Caries and Periodontal Status in Diabetes Mellitus Patients: A Cross-sectional Study.

INTRODUCTION

Diabetes mellitus is a chronic disease affecting many parts of the body. A number of oral diseases have been associated with diabetes mellitus with an increased risk of dental caries and periodontal disease.

AIM

The aim of the study was to evaluate the salivary pH and incidence of dental caries and periodontal status in diabetes mellitus compared to that of the normal subjects.

MATERIALS AND METHODS

The study population consisted of 40 patients divided into 2 groups with group I comprising of 20 known diabetes mellitus patients and group II comprising of 20 non diabetic subjects as control group. The pH of the saliva was determined using a digital pH meter. Dental caries and periodontal status were assessed by DMFT and PDI indices respectively.

RESULTS

There was a decrease in the mean salivary pH of 6.51 in the study group, compared to the normal mean salivary pH of 7.88 in the control group. The mean DMFT index was higher in the study group (8.10) when compared to that of control group (1.15). The mean PDI score was also higher in the study group (4.0) as compared to that of the control group (0.45).

CONCLUSION

The results of the present study concluded that there was a significant relationship between the diabetes mellitus and increased incidence of dental caries and periodontitis and there was also a significant reduction in the salivary pH in diabetes mellitus patients, compared to that of non diabetic subjects.
