Abstract
Objective: This study is intended to investigate the effectiveness of scaling and dental polishing and their correlation to oral microorganisms by examining the change in oral microbial population after scaling and dental polishing through clinical tests and real-time polymerase chain reaction.
Methods: This study examined 117 male and female adults of 20 years or older who visited the dental clinics in Daejeon, Korea. It used the real-time PCR to analyze the change of the oral microbial population before and after scaling and dental polishing.
Results: Before scaling, the prevalence rate of Fusobacterium nucleatum was 100.0%, meaning that it was prevalent in all examined subjects, Parvimonas micra 85.5%, Prevotella intermedia 76.1%, and Tannerella forsythia 72.6% while the prevalence rate of P. micra was 75.2% and P. intermedia 72.6% after scaling, and P. micra 45.3% and P. intermedia 66.7% after dental polishing. After scaling, all 11 oral bacterial pathogens including Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, T. forsythia, Treponema denticola, P. intermedia, F. nucleatum, P. micra, Campylobacter rectus, Eubacterium nodatum, Prevotella nigrescens, and Eikenella corrodens showed a considerably reduced population and had statistically significant differences (p＜0.05). After dental polishing, 10 oral bacterial pathogens except for A. actinomycetemcomitans showed a considerably reduced population and had statistically significant differences (p＜0.05).
Conclusion: Considering the results that the considerably reduced prevalence rate of 11 oral pathogenic microbes related to periodontal disease after scaling and dental polishing, we concluded that regular scaling and selective dental polishing are necessary for the periodontal treatment of the adult.
