Abstract
Background and Objectives: Vitamin D may include a role in periodontal health. This study aimed to assess association of vitamin D supplement intake and periodontitis in Iranian adults.
Materials and Methods: This was a case-control study comprising 150 participants aged 35–44 years from the two sexes, who were non-smokers, non-diabetics and enquirers of dental treatment at a dental public health center. First, condition of periodontium was assessed using clinical attachment loss, probing depth, bleeding on probing and plaque index. Participants were grouped to normal (n1 = 75) and chronic periodontitis (n2 = 75) groups. Data on tooth brushing and flossing, body weight and height, history of periodontal treatment, regular dental visits, insurance status and regular vitamin D supplementation in past 3 y were collected using questionnaires. Chi square, t-student test and logistic regression were used for statistical analyses.
Results: Those who had regular vitamin D intake, experienced periodontitis less than those who did not (78.7% against 33.3%, P-value < 0.0001). Results of logistic regression analysis showed that after adjusting for all assessed variables, not taking vitamin D supplements (OR = 5.33) and brushing less than once a day (OR = 8.01) variables were independently associated to the development of periodontitis.
Conclusions: These results have shown that regular intake of vitamin D is independently linked to the periodontal health in adults.
