Clinical response stratification after scaling and root planning: creating an early monitoring model using indicators of periodontal risk
https://doi.org/10.36377/ET-0139
Abstract
AIM. To develop an effective early-monitoring method grounded in periodontal risk factors and to categorize initial therapeutic responses to scaling as well as root planning (SRP).
MATERIALS AND METHODS. In a prospective cohort study, the plaque index, bleeding on probing, and probing pocket depth were measured at three different appointments: the first visit (baseline), the first follow-up visit (FU1), and the second follow-up visit (FU2). Mean reductions from pretreatment were calculated, and the patients were classified as Poor responders (<25% BoP reduction with little or no PPD decrease), Moderate (25 to 49% BoP reduction or <1 mm PPD reduction), or Rapid (more than 50% BoP reduction and less than 1 mm PPD reduction). Using non-parametric tests and Spearman correlations, the impacts of cigarette smoking and age were investigated.
RESULTS. SRP yielded clinically significant early enhancements in BoP and PPD at FU1, with further improvements noted at FU2. Smoking was associated with substantially diminished early BoP reductions and smaller PPD improvements. Age showed weak, non-significant correlations with early change. There were weak, non-significant relationships between age and early changes.
CONCLUSIONS. Risk-based assessment is made possible by early re-evaluation following SRP. Age by itself is not a short-term predictor, but smoking status is an actionable early risk sign. The suggested paradigm encourages smoking cessation counseling and supportive care intensity customization throughout the early maintenance stage.
