AIM: Chronic periodontitis (CP) is a multifactorial disease and the most common type of periodontitis mainly caused by microbial plaque. CP can be brought on by, and progresses with, insufficient oral hygiene, and environmental and genetic susceptibilities. The aim of the present study was to investigate the association between interleukin (IL)-2 (T-330G), IL-16 (T-295C), and IL-17 (A-7383G) gene polymorphisms and the susceptibility to CP in an Iranian population.
METHODS: Ninety-nine cases diagnosed with CP and 75 matched healthy controls engaged in the present study. 3 cc peripheral blood samples were obtained for DNA isolation. Genotype analysis was performed using restriction fragment length polymorphism polymerase chain reaction. Genotype distribution and allele frequencies within groups were compared using χ2 -test, and logistic regression analysis was used to recognize the independent relation between the disease and the absence or presence of alleles.
RESULTS: There was no polymorphism in IL-2 (T-330G) among our patients, and the TT genotype was present in both study groups. Moreover, none of the studied genotypes and alleles of IL-16 (T-295C) and IL-17 (A-7383G) was significantly associated with CP.
CONCLUSION: The present study demonstrated no association between IL-2 (T-330G), IL-16 (T-295C), and IL-17 (A-7383G) genotypes and CP in an Iranian population.
