Abstract

Lack of association between the vitamin D receptor polymorphism rs2228570 and chronic periodontitis in a Han Chinese population

The vitamin D receptor (VDR) is involved in the immune response and bone metabolism, both of which are implicated in the pathogenesis of chronic periodontitis (CP). In this study, we investigated the association between the VDR single nucleotide polymorphism rs2228570 and CP susceptibility in a Han Chinese population consisting of 440 moderate or severe CP patients and 324 controls. Genomic DNA was extracted from buccal epithelial cells and genotyped using matrix-assisted laser desorption/ionization time-of-flight-mass spectrometry. No significant difference in allelic or genotypic frequencies distributions for rs2228570 was found between CP patients and controls. In conclusion, we found no statistically significant association between rs2228570 and CP in our population.
