Vitamin D deficiency may increase the risk of periodontal disease by causing decreased bone mineral density, osteoporosis, progression of periodontal diseases, and resorption of the jawbone. In addition, vitamin D is important for bone metabolism, alveolar bone resorption, and the prevention of tooth loss. It increases the antibacterial defense of gingival epithelial cells, reduces gingival inflammation, accelerates postoperative wound healing after periodontal surgery, and is a key supplement functioning as a prophylaxis in periodontology. The present review study aims to highlight the role of vitamin D in periodontal disease.eninfo:eu-repo/semantics/openAccessReview Article3438138510.47582/jompac.12088681243313
