title: [Association of TNFA-308 gene polymorphisms with susceptibility to chronic periodontitis in Chinese patients].
abstract: OBJECTIVE
  The purpose of this study was to investigate the relationship between TNFalpha-308 gene polymorphisms and susceptibility to chronic periodontitis in Chinese patients.
  
  
  METHODS
  DNA samples with buccal swabs were collected from 63 severe CP patients, 103 initial to moderate CP patients, and 80 healthy controls in Chinese Han nationality. The TNFA-308 gene polymorphisms were analyzed with PCR-RFLP. The data were analyzed by X(2) test using SPSS10.0.
  
  
  RESULTS
  There were no significant genotype distribution differences of TNFA-308 between either two of the three subject groups.
  
  
  CONCLUSIONS
  Further study was needed since we did not find the relationship between TNFA-308 gene polymorphism and periodontitis in this present study.
