Periodontal disease is an infectious disease caused by the interaction of host immune and the bacteria and thus undermines the periodontal tissue. Since vitamin D plays a role in bone homeostasis and immune response, the receptor gene may associate with the susceptibility to periodontal disease. Previous experiments confirmed that the vitamin D receptor gene polymorphism and periodontal disease was significantly correlated, but there are still contradictory results in different studies. This article reviews the research of vitamin D receptor gene and susceptibility to periodontal disease, and to discuss the physiological function, its genetic polymorphism, and the effect of vitamin D receptor gene polymorphism to periodontal disease susceptibility.
