Shifting the Ratio of S. Cristatus vs. P. Gingivalis in Periodontitis Patients by 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.

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.
