The present study was designed to investigate the relationship between alterations in plaque control level and periodontal probing depth (PD) during the plaque control phase of initial preparative treatment and the stability of these parameters during maintenance in patients with periodontal disease.
We assessed 35 adult subjects, ranging in age from 29 to 65 years, who had been treated by the authors for periodontal disease.
The index was evaluated in terms of the O'Leary plaque control record (PCR) and periodontal PD.
The findings obtained can be summarized as follows;
1. There were no direct correlations between improved PCR at the first examination and initial preparative treatment and the average maintenance PCR.
2. The subjects with lower PCR average during maintenance had greater variability in PCR.
3. There were no significant correlations between the subjects' PCR and the prevalence of PD on the first examination and improvement during initial preparative treatment.
