Comparison of burning mouth syndrome prevalence between diabetes mellitus and hypothyroidism patients

Abstract Introduction: Due to the high prevalence of type 2 diabetes and hypothyroidism and the fact that the complication of burning mouth syndrome is seen in both of these diseases, we compared the frequency of burning mouth syndrome in patients with diabetes mellitus type 2 and patients with hypothyroidism referred to Rasht dental school in 1399. Materials and Methods:In this cross-sectional study, 196 patients with type 2 diabetes mellitus and 196 patients with hypothyroidism were included in the study. Each participant in the study was assessed by asking the patient about the presence of burning pain in the oral mucosa. In cases with burning pain, the visual analogue scale criterion was used to measure the severity of pain. Results: Burning mouth syndrome was significantly higher in patients with diabetes mellitus (P = 0.022). There was no significant relationship between the mean level of FBS, HbA1C and TSH with burning mouth syndrome, while there was a significant relationship between the mean level of free T4 with burning mouth syndrome (P = 0.004). The mean level of free T4 was higher in patients with burning mouth syndrome. It was also found that aging has a positive correlation with the severity of burning pain (p <0.001). Conclusion:According to the results of the present study, it is necessary to prevent the occurrence of diabetes mellitus and consequently the development of this complication in the mouth. It is also important to monitor patients with diabetes mellitus and control their oral complications in collaboration with the medical team.
