The Influence of Vitamin D and Calcium Supplements on Tooth Stability in Elderly: Systematic Review

Abstract

Background: Vitamin D is a fat-soluble vitamin that is available hardly ever in food, and can be available as a supplement. Furthermore, it is formed endogenously when rays from the sun strike the skin and prompt vitamin D synthesis. Vitamin D motivates the absorption of calcium in the intestine and maintains adequate serum calcium and phosphate concentrations to allow bone mineralization and to prevent hypocalcemia. Periodontitis is an inflammatory disease, described by losing in alveolar bone prompted by the immune response to bacterial invasion. Since vitamin D is associated with some inflammatory disorders and has a significant role in bone homeostasis, its insufficiency could affect the periodontium in a negative way and increase tooth loss that will assume vitamin D has an important role in decreasing the risk of periodontitis. The purpose of this study is to determine the effectiveness results of vitamin D and Calcium supplements in reducing tooth loss and improving the tooth retention. Methods and Materials: This research is a systematic review that includes varies studies design of randomized controlled trials, cohort studies, cross-sectional studies and case-control studies that conducted in period (2000-2016).  Among 25 studies, 8 studies have included in this systematic review  Results: The findings  were got by varies statistical methods including logistic regression, and t-tests, and most of them showed the statically significant between Vitamin D supplements and reduce tooth loss. Conclusion: In conclusion, the studies presented the robust relation between vitamin D insufficiency intake and tooth loss. Intake both of vitamin D and calcium can associate inversely with periodontitis
