association of serum 25-hydroxyvitamin d and chronic periodontitis in postmenopausal women after non-surgical periodontal therapy

Objectives: vitamin d deficiency appears to have a major effect on periodontal tissue health. the present study aimed to assess the association of the serum level of 25-hydroxyvitamin d and chronic periodontitis in postmenopausal women.materials and methods: this research was done on 30 postmenopausal women with chronic periodontitis who all had at least 20 natural teeth. intravenous blood samples were taken from the study population at baseline and after completion of non-surgical periodontal treatment. this was followed by assessment of serum levels of 25-hydroxyvitamin d. next, clinical parameters of all teeth except for third molars were measured, which included pocket depth (pd), gingival index (gi), and plaque index (pi). data were analyzed by paired t-test and its non-parametric equivalent, the wilcoxon test. p<0.05 was considered significant.results: the mean pd, pi and gi before and after the intervention were significantly different (p<0.05). there was, however, no significant difference between the mean vitamin d concentrations before and after treatment (p>0.05).conclusion: according to the results obtained in the present study, there is no association between serum vitamin d concentrations and chronic periodontitis in postmenopausal women.
