Abstract

Aim: The aim of this study was to evaluate the impact of hyperthyroidism on dental caries among women regarding the salivary potential of hydrogen (pH), salivary flow rate (SFR), salivary chloride (Cl), and potassium (K). Materials and methods: A case control comparative study design was used in the present study; the sample size was 90 females between the ages of 25 and 45. The study population was divided into two groups; the case group included 45 participants. Which has a history of hyperthyroidism, while the control group included 45 healthy females. The clinical examination was performed according to the instructions of the World Health Organization (WHO) 2013. The saliva was collected in order to determine the SFR, pH, and electrolyte concentrations. Salivary K and Cl were measured using the atomic absorption spectrophotometry method and the colorimetric method, respectively. Results: The caries experience in the hyperthyroid group was higher compared to the healthy group but with no significant difference. Salivary pH and flow rate was lower among the hyperthyroid group compared to the healthy group, but there was no statistically significant difference. Electrolytes were higher in the study group than in the control group, with a significant difference. The correlation between salivary electrolytes and caries experience was nonsignificant. Conclusion: The present study revealed that patients with hyperthyroidism had greater levels of caries experience when compared to the healthy group, and that was associated with a decrease in SFR and pH. As a consequence, patients with hyperthyroidism require special care for their dental health. Clinical significance: The medical history evaluation is extremely important for oral health and has significantly influenced oral health. Therefore, it is important to recognize the possible consequences of hyperthyroidism on oral health. Dental healthcare practitioners must be aware of the oral and systemic manifestations of the hyperthyroidism. The risk of dental caries increased as the SFR decreased among these patients, in addition to changes in salivary pH and electrolytes, so patients with hyperthyroidism have a greater need for dental care.
