Summary

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.

Detailed description

The periodontal health maintenance will be evaluated by plaque index, periodontal pocket, and gingival inflammation status. Participants will be assigned into two groups after the second dentist visit based on their execution of periodontal health maintenance. Participants whose number of P. gingivalis is unchanged or higher compared to that found at baseline will be considered poor maintenance. Those not having maintained a good dental hygiene will further be randomly assigned to two groups. One group will be given more intense oral health education, while the other one will receive the same education as post therapy. The result of intensive education and a shift in ratio of S. cristatus and P. gingivalis will then be measured for both groups at the third dentist visit (9 months after initial periodontal treatment) and the effectiveness of the intervention will be tested at this stage.

Conditions

• Chronical Periodontitis, Ratio of P. Gingivalis and S. Cristatus

Interventions

Type	Name	Description
BEHAVIORAL	Intense education	we will inform patients with their own data including the number of P. gingivalis and ratio of S. cristatus and P. gingivalis detected immediately after periodontal treatment and 3 month after the treatment. Explaining these data in detail, in terms that the patient can understand, are equally as important as teaching the plaque control techniques.
