Prevalence of Porphyromonas Gingivalis Fimbrial Subunit Genotype in Smokers and Nonsmokers After Periodontal Therapy

The aims of the present study will be identify 5 types of fimbrial subunit genotype strains in smokers and nonsmokers with periodontitis, before and after periodontal therapy. Third two periodontitis patients will be selected to these study, 16 nonsmokers and 16 smokers. Clinical and microbiological parameters were evaluated at baseline and 3 months after periodontal treatment: Plaque Index, Bleeding On Probe, Probing Depth, Gingival Recession and Clinical Attachment Level. The prevalence of P. gingivalis and fimbrial subunit gene strains will be determined by Polymerase Chain Reaction.
