Effectiveness of two supportive periodontal care protocols and outcome predictors during periodontitis: A randomized controlled trial
Abstract
Abstract Background A randomized, controlled trial was conducted to evaluate the effectiveness of two supportive periodontal care (SPC) approaches in patients with periodontitis and to evaluate possible predictors influencing bleeding on probing (BoP) changes at 24‐month follow‐up. Methods Fifty‐six periodontitis patients who first received active periodontal treatment by means of quadrant‐wise subgingival instrumentation were subsequently assigned to either a control group (oral hygiene instruction with supragingival instrumentation and dental polishing, n = 28) or a test group (oral hygiene instruction with both supra‐ and subgingival instrumentation and dental polishing, n = 28). BoP was the primary outcome, and probing pocket depth (PPD), clinical attachment level (CAL), full‐mouth plaque score (FMPS), gingival bleeding index (GBI), and the number of pocket sites were secondary outcome measures, recorded up to 24 months of follow‐up. A mixed generalized linear regression analysis also assessed the potential confounding factors that influenced BoP changes at 24 months. Results At 24 months, both groups showed significant improvement in periodontal outcomes (p 6 mm (p = 0.023). Among all follow‐up sessions, the reduced BoP was significantly negatively influenced by the number of median PPD (p = 0.031), the number of pockets 4–5 mm (p = 0.029), PPD 5–6 mm (p = 0.036), smoking (p = 0.039), and by the number of cigarettes/day (p = 0.042) and positively by test treatment (p =…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 28 participants or records.
