Correlation between SNP genotypes and periodontitis in Japanese type II diabetic patients: a preliminary study.

The present study aims to investigate the correlation between SNP genotype patterns and periodontitis severity in Japanese type II diabetic patients. A cross-sectional study in 43 Japanese diabetic patients with periodontitis was performed. Blood samples were drawn for single nucleotide polymorphism (SNP) analyses and periodontal index (probing pocket depth and clinical attachment level) was subsequently recorded.
