Clinical Trial Summary

Periodontitis is related to host genetics, constitution of the dental biofilm and environmental factors such as smoking. DNA methylation is a mechanism of genetic expression that can inhibit or silence gene expression. In this way several researchers have been dedicated to study the genetic influence on the susceptibility and / or increased risk to periodontal disease. Studies have reported association between several epigenetic biomarkers with periodontal inflammation. Considering the hypothesis that there is an association between smoking and methylation in genes related to periodontal disease, the objective of this study was to verify the DNA methylation pattern in oral epithelial cells of patients with chronic periodontitis (CP) in the promoter of a specific gene involved in the control of inflammation, as suppressor of cytokine signaling (SOCS) 1 in smokers and nonsmokers patients.


Clinical Trial Description

This was an experimental type study with parallel controls, comparing two groups, a group with consumption of 10 minimum cigarettes per day, with a diagnosis of chronic periodontitis. And another control group were non-smokers with chronic periodontitis. For this, genomic DNA was purified from oral epithelial cells obtained by rinsing with 3% sucrose, for a single time of collection, patients received periodontal treatment after collection and data analysis. The DNA was modified by Sodium bisulfite and the methylation patterns of the DNA were analyzed with the MSPCR technique (Polymerase chain reaction). This study was approved by the Institutional Review Board of the School of Dentistry of Ribeirão Preto (CAAE:57171816.2.0000.5419 ), and all patients need to provide written informed consent. ;
