Intense Education of Periodontal Health Maintenance
Study Details
Study Description
Brief 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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: intense education of periodontal health maintenance
|
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.

| Placebo Comparator: No intense education of periodontal health maintenance

Outcome Measures
Primary Outcome Measures
- Improvement of periodontal condition [9 month]
1. Improvement of periodontal condition Response to periodontal treatment will be determined by a composite measure including 1) Plaque Index; 2) Gingival index; 3) Cemento-enamel junction, gingival margin, probing, and bleeding on probing from six sites on all teeth. The patients will be considered to have improved, non-changed, and worsening periodontitis, according to clinical measurements and comparison them with those before treatments.
