Association between vitamin D receptor gene polymorphisms and chronic periodontitis among Libyans.

Background: Chronic periodontitis (CP) is a common oral disease characterized by inflammation in the supporting tissue of the teeth 'the periodontium', periodontal attachment loss, and alveolar bone loss. The disease has a microbial etiology; however, recent findings suggest that the genetic factors, such as vitamin D receptor (VDR) gene polymorphisms, have also been included.

Aim: Investigation of the relationship between VDR gene polymorphisms and CP among Libyans.
