Abstract

Background: Autoimmune thyroid disease (AITD) is an inflammatory condition that primarily affects women between the ages of 30 and 50. It has been hypothesised that AITD causes salivary glands to produce less saliva due to its endocrine effects. Studies showing the effect of AITD on salivary glands are very scarce. The aim of this study was to compare AITD patients with controls who were of a similar age and gender in terms of salivary metrics and the prevalence of dental caries. Methods: 200 subjects in Bangalore city (100 AITD subjects and 100 healthy subjects as controls) participated in a cross-sectional study. Subjective oral dryness was assessed using Farsi’s criteria. Salivary parameters and caries were assessed using GC Saliva-Check BUFFER kit and WHO caries criteria respectively. Descriptive and analytical statistics were done. Significant data was defined as a p value of <0.05. Results: When compared to controls, the AITD group had substantially more subjective mouth dryness and dental caries. Unstimulated (USFR) and stimulated salivary flow rate (SFR), pH and buffering capacity were reduced in AITD group whereas viscosity was high. There was a significant negative correlation between USFR, SFR, subjective oral dryness and dental caries. In a linear regression, there was no association between age, gender, socioeconomic status (SES), thyroid stimulating hormone (TSH), salivary viscosity, pH, buffering capacity and dental caries. Dental caries, USFR and SFR demonstrated a substantial relationship. Conclusions: The present research may indicate an underlying association between thyroid and salivary gland dysfunction resulting in oral dryness and high dental caries experience.
