Study & Design

Study Type: interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
The periodontal probing depths are recorded at baseline, after 3 months and after 6 months. The primary endpoint is the reduction in probing depths after 6 months of treatment compared to the baseline.

Secondary Outcome Measures

Name	Time	Method
At baseline, after 3 months and after 6 months, gingival inflammation (according to gingival index (GI)), plaque index (PI), clinical attachment level, bleeding on probing (BOP), need for re-instrumentation, as well as weight, BMI and blood pressure are recorded. The changes in these parameters from baseline compared to 6 months are considered as secondary endpoints.
