Methodology
Case-control study of 50 individuals with self-reported sleep bruxism and 50 age- and gender-matched controls; serum 25-hydroxyvitamin D measured, anxiety and depression assessed with the Hospital Anxiety and Depression Scale, dietary calcium and frequent headache self-reported; binary logistic and multiple linear regression used.
Key Findings
This case-control study compared 50 people with self-reported sleep bruxism (teeth grinding) with 50 age- and sex-matched controls. Those with bruxism had lower serum 25-hydroxyvitamin D and higher anxiety and depression scores (p < 0.05), and vitamin D deficiency, low dietary calcium (under 323 mg/day) and frequent headache were all more common in the bruxism group. In logistic regression, bruxism was associated with vitamin D deficiency (OR 6.66, p = 0.02), low calcium intake (OR 5.94, p = 0.01) and frequent headache (OR 9.24, p < 0.001). The authors call for trials to test whether vitamin D and calcium supplementation actually relieves bruxism.
Conclusions
Sleep bruxism was associated with vitamin D deficiency and low consumption of calcium and was also associated with increased scores of anxiety and depression.
Limitations
Only 100 people in a single-country case-control design with self-reported bruxism and self-reported calcium intake; associations cannot show direction of cause, and no supplementation was tested.
Supplements Studied
Sleep bruxism was associated with vitamin D deficiency and low consumption of calcium and was also associated with increased scores of anxiety and depression.
