Scaling and Root Planing per Quadrant Versus One-Stage Full-Mouth Disinfection: Assessment of the Impact of Chronic Periodontitis Treatment on Quality of Life - A Clinical Randomized, Controlled Trial

Abstract

Background: There are few randomized, controlled clinical trials about the effect of non-surgical periodontal treatment on oral health-related quality of life (OHRQL). This study aims to compare the effects of two different forms of non-surgical periodontal therapy, scaling and root planing (SRP) per quadrant and one-stage full-mouth disinfection (FMD), on periodontal clinical parameters and OHRQL of patients with chronic periodontitis. Methods: In this randomized, controlled clinical trial, the questionnaires Oral Impacts on Daily Performance (OIDP) and Oral Health and Quality of Life (OHQoL) were given to 90 patients divided into two groups: SRP (n = 45) and FMD (n = 45). Periodontal clinical parameters recorded included probing depth, clinical attachment level, plaque index, and gingival index. For statistical analysis, chi(2) test, Fisher exact test, Mann-Whitney U test, and Wilcoxon test were used. Intention-to-treat analyses were performed at T0 (baseline) for periodontal clinical parameters, T1 (30 days after treatment) for questionnaires, and T2 (180 days after treatment) for both. Results: No significant differences were identified between the SRP and FMD groups in regard to OHQoL and OIDP scores when comparing the data of T1 and T2. Conclusion: Patients treated by both SRP and FMD showed improvement in all periodontal clinical parameters and OHRQL, with no significant differences between treatment groups.
