Prevalence of serum vitamin D and B12, Ca, P, Mg levels and rheumatoid factor status in the patients with bilateral TMJ-OA and their correlations with clinical and radiological findings

ObjectiveTo evaluate the prevalence of serum vitamin D and B12, calcium, phosphorus, magnesium levels, and rheumatoid factor (RF) status in patients with bilateral temporomandibular joint osteoarthritis (TMJ-OA) and their correlations with clinical and radiological findings.MethodsThe clinical and radiologic findings and serum vitamin and mineral levels of 90 patients diagnosed with bilateral TMJ-OA were recorded. Descriptive statistics and the Spearman's Rho correlation test were performed.ResultsLow serum vitamin D and B12 levels were detected in 82 (91.1%) and 74 (82.2%) patients. Calcium and phosphorus levels were seen at low rates. RF status was recorded as unfavorable in all patients. Correlations were found between age and the serum vitamin and mineral levels, except phosphorus. Low serum vitamin D levels correlated with pain complaints at rest and painless MIO. Serum B12 levels correlated with condylar erosion. Serum magnesium levels correlated with painful MIO and condylar osteophyte.ConclusionPatients with bilateral TMJ-OA showed a high prevalence of low serum vitamin D and B12 levels.
