Different scaling and root planing strategies in Turkish patients with aggressive periodontitis: A randomized controlled clinical trial.

Abstract

The aim of this study was to compare clinical, cytokine and microbiological responses after quadrant-based scaling and root planing (Q-SRP), full-mouth SRP (FM-SRP) and full-mouth disinfection (FMD) in patients with generalized aggressive periodontitis (GAgP), which is currently termed as generalized stage-III and grade-C periodontitis. Forty-two patients with GAgP were randomly assigned into groups as Q-SRP, FM-SRP or FMD with chlorhexidine. Clinical parameters were recorded, and gingival crevicular fluid (GCF) and subgingival plaque samples were collected at baseline, 3 and 6months after treatment. GCF levels of interleukin (IL)-1β and IL-17 were analysed using ELISA. Quantities of six bacterial species were determined using qPCR. Clinical parameters improved significantly in all groups at 3 and 6months (p<0.05). Percentage of sites with probing depth >6mm was lower in the FMD than Q-SRP group at 3 and 6months (p<0.05). FMD showed significantly higher percentage of pocket closure compared with Q-SRP and FM-SRP at both 3 and 6months after treatment (p<0.05). The IL-1β levels decreased only in the FMD group (p<0.05), whereas no changes were found in IL-17levels in any group. The levels of five out of six bacterial species decreased at 3 and/or 6months only in the FMD group (p<0.05). The FMD treatment appears to offer superior outcome than Q-SRP and could be the first choice for patients with GAgP.
