Abstract

Vitamin D receptor (VDR) is included in the type of protein that serves as the biological function regulator of vitamin D. Tooth formation, especially in enamel and dentin calcification, as well as maintaining the balance of phosphate and calcium ions which is an important factor in protecting teeth requires support from vitamin D. The VDR gene will regulate the activity of VDR proteins. Caries is a multifactorial disease in which genetic factors can affect the host susceptibility to caries. Polymorphism in the VDR gene is suspected to affect the host susceptibility to caries through changes in calcium metabolism. This study aims to discover the VDR gene polymorphism and its association with caries patients in Indonesia. 100 DNA samples from 100 blood samples, including 50 dental caries patients and 50 healthy controls, were analyzed using PCR-RFLP technique. PCR products were digested with the TaqI restrictive enzyme, then assessed with statistical analysis using Fisher's exact test and Continuity correction test. In the caries group, there were no samples with CC genotype, 4 samples with CT genotype, and 46 samples with TT genotype. There were also 4 C alleles and 96 T alleles. Polymorphic genotypes and alleles were found higher in the caries group (100% and 96%) than healthy controls (88% and 84%). These results conclude that the polymorphism of VDR TaqI (rs731236) gene was found in patients with dental caries. The distribution of genotypes and allele distributions of VDR TaqI (rs731236) gene between caries and healthy controls significantly differs noticeable (p <0.05).
