DNA probe analysis in smoker and non smoker rapidly progressive periodontitis patients--a pilot study.

Smoking is one of the most significant risk factors in the development and further advancement of inflammatory periodontal disease. The bacteria A. actinomycetemcomitans, P. gingivalis and P. intermedius as indicated as the potential pathogens associated with periodontal disease. Since the bacteria mentioned as well as smoking are factors associated with periodontitis it is of importance to elucidate the interrelationship between these factors. The purpose of this study was to investigate the prevalence of A. actinomycetemcomitans, P. gingivalis and P. intermedius in subgingival plaque samples obtained form healthy and diseased sites of patients with rapidly progressive periodontitis who were smokers and non smokers along with other clinical parameters.
