Intense Education of Periodontal Health Maintenance

Investigators hypothesize that good oral hygiene may inhibit P. gingivalis, a keystone periodontal pathogen, entering mature dental plaque, which leads to a higher ratio of S. cristatus and P. gingivalis. Investigators will educate and train periodontitis patients following periodontal therapy to maintain periodontal health. Initial and intense education of periodontal health maintenance will be provided and the ratio of S. cristatus and P. gingivalis in dental plaques will be compared and analyzed for correlation between patient's execution of periodontal health maintenance and education tools or the ratio of S. cristatus and P. gingivalis.
