• Conditions: Chronic periodontitis,

• Registration Number: CTRI/2025/06/088488
• Lead Sponsor: Sri Ramachandra Institute of Higher Education and Research

Brief Summary

A total of 12 patients with Grade 2 periodontitis  were choosen for this split mouth study, randomly quadrants were selected for test and control groups in this single centred, clinical trial. Each group including 12 quadrants were randomly selected for test and control group. Test group will be  treated with scaling and root planning with erythritol powder supragingival air polishing as adjunct.Control group will be treated with Scaling and root planning alone. Every patient who satisfies the requirements for inclusion will be progressively included to the experiment . Using an envelope system and a computer generated table, Each patient will be randomly assigned to receive either the test group (scaling and root planning with erythritol powder supragingival air polishing as adjunct) and Control group(Scaling and root planning alone). Patients in the test group will be treated with conventional SRP with supragingival erythritol air polishing device using Prophyjet air polishing device for 5 seconds  each tooth. To assess the changes in the clinical periodontal parameters( Bleeding on probing, plaque index, Probing depth, clinical attachment loss and PISA) and microbial analysis using plaque samples at baseline and 3 weeks follow up period. The non- surgical periodontal therapy for the assigned patients will be performed in the department of periodontology, prior to therapy, all study participants underwent a comprehensive diagnostic evaluation that comprised a radiograph of the afflicted area, intraoral photos, and routine blood parameter checks, bleeding time, clotting time .A comprehensive oral prophylaxis were then carried out . The modified plaque index( Silness and Loe, 1964) , the modified sulcus bleeding index ( Mombelli et al., 1987 ) will be done to quantify oral hygiene at baseline for all the patients prior to oral prophylaxis. Using the UNC-15 probe, the probing pocket depth and clinical attachment loss will be assessed. Clinical parameters( Bleeding on probing, plaque index, Probing depth, clinical attachment loss and PISA) and microbial analysis will be assessed at baseline and 4 weeks following the initial instrumentation.
