Study Overview
Brief Summary
This clinical study investigates two different non-surgical periodontal therapy approaches in patients with advanced periodontitis and compares them with periodontally healthy individuals. Participants with Stage III/IV Grade C periodontitis are randomly assigned to either a single-session or a three-session scaling and root planing (SRP) protocol. Clinical parameters, gingival crevicular fluid inflammatory markers, and subgingival microbial profiles are assessed at baseline and during a 6-month follow-up period. The study aims to determine whether performing non-surgical periodontal therapy in multiple sessions influences clinical, biochemical, and microbiological responses.
Detailed Description
This randomized, single-blinded, controlled clinical trial is conducted at the Department of Periodontology, School of Dentistry, Ege University, İzmir, Turkey. The purpose of the study is to evaluate whether a three-session non-surgical periodontal therapy protocol provides different clinical, biochemical, and microbiological responses compared to a single-session protocol in patients with Stage III/IV Grade C periodontitis.
Participants with periodontitis are randomly assigned to one of two intervention groups:
Single-Session Therapy Group (SSTG): full-mouth scaling and root planing (SRP) performed in one visit.
Three-Session Therapy Group (TSTG): quadrant-wise SRP delivered over three sessions within the same week.
All procedures are carried out by a single calibrated clinician. Clinical periodontal parameters-probing depth, clinical attachment level, plaque index, and bleeding on probing-are recorded at baseline and at predetermined follow-up visits at 1, 3, and 6 months.
