Aim:For a periodontal diagnosis properly determined
and for the estimation of periodontal treatment efficiency, clinicians rely on periodontal indices. The aim of our study is to evaluate the correlations between two important indices: plaque index and bleeding index.
In this study participated patients who came to
the Faculty of Dentistry Timi[oara, the Department of
Periodontology, from December 2007 to February 2008. In our study, we used Silness and Le plaque index (PI) and Le and Silness gingival index (GI). The inclusion criteria specified persons with at least 10 natural teeth, with no hematologic disorders and no anticoagulant treatment. We evaluated 2316 tooth surfaces. 73.14% had plaque score with scores from 1 to 3.
From those, 84.12% have bled on sampling. In 26.86% of cases, on no plaque surfaces (PI=0), BOP did not exist (GI=0), so bacterial plaque accumulation is a determining factor in periodontal inflammation. There are dental surfaces with plaque (PI=1) and with no bleeding (GI=1), so the host response plays a very important role in inflammatory process control. In 63.58% of cases
there are tooth surfaces with different plaque scores (PI=2 or 3) in directly correlation with BOP severity (GI=2 or 3). Bacterial plaque index and bleeding index form an important tandem in the work of the clinician and, especially, of the periodontist.
