Predictive value of clinical and microbiological parameters for the treatment outcome of scaling and root planing

Objectives: To compare the clinical and microbiological outcome of non‐surgical periodontal therapy after 6 months with data obtained after hygienic phase or 6 weeks after completion of non‐surgical therapy, in order to evaluate the value of clinical and microbiological parameters to predict treatme...

Description
Summary:Objectives: To compare the clinical and microbiological outcome of non‐surgical periodontal therapy after 6 months with data obtained after hygienic phase or 6 weeks after completion of non‐surgical therapy, in order to evaluate the value of clinical and microbiological parameters to predict treatment success. Material and Methods: Clinical and microbiological data were available from 271 sites in 10 systemically healthy non‐smokers with moderate‐to‐advanced chronic periodontal disease (24–32 sites per individual). Subgingival plaque samples were tested for the presence of Porphyromonas gingivalis, Actinobacillus actinomycetemcomitans, Tannerella forsythensis and Treponema denticola using RNA probes. Results: Stepwise multiple linear regression analysis revealed a significant impact of the number of sites with visible plaque index >1 after hygienic phase on the bleeding tendency of a subject at month 6 (p3 mm) 6 months after therapy and the number of bleeding sites and suppurating sites after hygienic phase (p=0.016). Six weeks after therapy, the mean total bacterial loads had a significant impact on the bleeding tendency of a subject at month 6 (p
