Assessment of the link between Vitamin D receptor TaqI gene polymorphism and periodontitis: a meta-analysis in a Chinese population
Although a number of studies have been conducted to determine the association between vitamin D receptor (VDR) TaqI polymorphism and periodontitis in the Chinese population, this association remains elusive. To assess the influence of VDR TaqI polymorphism on the risk of periodontitis, a meta-analysis was performed in a Chinese population. Relevant studies were identified using the databases PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure, and Chinese Biology Medicine, through January 2016.
