Abstract: (8 Views)
Background and Aim: Recent evidence suggests a link between sleep bruxism and vitamin D deficiency. This study aimed to investigate the serum concentrations of calcium and 25-dihydroxyvitamin D, as well as calcium intake in patients with self-reported sleep bruxism versus healthy controls.
Materials and Methods: This case-control study evaluated 32 participants between 18 and 44 years old in each of the case and control groups, who were selected among patients referring to Yazd Dental School. The severity of bruxism was assessed using a questionnaire related to the classification of bruxism, and clinical examinations were performed to assess abnormal tooth wear. The daily calcium intake was estimated based on the frequency and amount of consumption of milk, yogurt, and cheese. The serum level of 25-hydroxyvitamin D was measured using the relevant kit, and the serum calcium level was measured by spectrophotometry. Data were analyzed using the Mann-Whitney test, Independent sample t-test, Fisher’s exact test, and Spearman’s correlation coefficient (alpha=0.05).
Results: The mean daily calcium intake in the case group was significantly lower than that in the control group (P<0.001). However, the mean serum calcium levels did not differ significantly between the case and control groups (P>0.05). The mean serum level of 25-hydroxyvitamin D in the case group was significantly lower than that in the control group (P<0.001).
Conclusion: According to the present results, the mean serum level of 25-hydroxyvitamin D in bruxers was significantly lower than that in healthy controls. Bruxism was significantly associated with vitamin D deficiency in our study population.
