Different doses of vitamin D supplementation to nonsurgical treatment for vitamin‐D‐insufficient patients with diabetic periodontitis and the effect on gingival BMP‐2 levels

Abstract

AbstractEpidemiological data show people with diabetes mellitus (DM) have three‐fold increase in risk of periodontitis. A vitamin D insufficiency can affect the progression of DM and periodontitis. This study evaluated the effects of different‐dose vitamin D supplementation to nonsurgical periodontal therapy for vitamin‐D‐insufficient diabetic patients coexisting with periodontitis and changes of gingival bone morphogenetic protein‐2 (BMP‐2) levels. The study included 30 vitamin‐D‐insufficient patients receiving nonsurgical treatment followed by administration of 25,000 international units (IU) vitamin D3 per week (the low‐VD group) and 30 patients receiving 50,000 UI vitamin D per week (the high‐VD group). The decreases of probing pocket depth, clinical attachment loss, bleeding index, and periodontal plaque index values of patients after the six‐month supplementation of 50,000 UI vitamin D3 per week to nonsurgical treatment were more significant than those after the six‐month supplementation of 25,000 UI vitamin D3 per week to nonsurgical treatment. It was found that 50,000 IU per week vitamin D supplementation for 6 months could lead to a better glycemic control for vitamin‐D‐insufficient diabetic patients coexisting with periodontitis after nonsurgical periodontal therapy. Increased levels of serum 25(OH) vitamin D3 and gingival BMP‐2 were found in both low‐ and high‐dose VD groups, and the high‐dose VD group exhibited higher levels than the low‐dose VD group. Vitamin D supplementation in large doses for 6 months tended to improve the treatment of periodontitis and increase gingival BMP‐2 levels in diabetic patients coexisting with periodontitis who were vitamin D deficient.
