Association between Serum 25-Hydroxyvitamin D Concentrations and Periodontal Health

Objective: To assess the relationship between serum 25(OH)D concentrations and periodontal health in Iraqi men. Materials and Methods: In this case–control study, 45 males aged (30-50) were involved. 25 patients considered as a case group with chronic periodontitis (stages III–IV), and 20 individuals with healthy periodontium counted as control group. Participants with systemic diseases, smoking, or vitamin D supplementation were excluded. Plaque index (PLI) and gingival index (GI) were obtained and serum 25(OH)D levels measured with Roche E411 analyzer. Vitamin D status was grouped as sufficient (≥20 ng/mL) or insufficient (
