The Effect of Saliva and Dental Caries of the Patients with Hashimoto Thyroiditis on Cytokine Levels.

BACKGROUND

This study aimed to evaluate the effect of dental caries and oral health of patients on salivary cytokine levels with Hashimoto's thyroiditis (HT).

MATERIAL AND

METHODS

The study included 30 patients (n = 30) diagnosed with HT. The standardization of the participants was achieved with specific biochemical parameters, and the sociodemographic information of the patients was obtained through anamnesis. A pH meter was employed for salivary pH measurement. After determining the oral problems of the patients, necessary treatments were applied. Following 3 months of treatment, saliva samples were taken to evaluate cytokine levels (TNF-α, IL-6, IL-8, and CRP) and for ELISA analyses. The Wilcoxon test was used for pairwise comparison of nonparametric data, and the Chi-square test was employed to analyze categorical variables at P < 0.05.

RESULTS

There was a significant decrease in salivary TNF-α, IL-6, IL-8, and CRP levels between the measurements before and after 3 months of treatment (P < 0.05). In addition, a significant increase was found in salivary pH (P < 0.05).

CONCLUSIONS

The salivary cytokine levels decrease and the inflammatory response improves when the inflammation in the periodontal tissues and dental caries is treated.
