Comparative Evaluation of the Effect of Different Adjunctive Air Polishing Powders in Nonsurgical Periodontal Therapy in Patients with Stage II and III Periodontitis

"Non-Surgical Periodontal treatment:~1. Guided Biofilm Therapy~ * Guided supragingival and shallow subgingival (PD ≥ 4 mm) removal of biofilm and stains from all quadrants using the air-polishing device using a standard nozzle system.~ * Subgingival removal of biofilm from deeper periodontal pockets (PD ≥ 6 mm) using an Air-polishing device subgingival nozzle system with erythritol powder .~2. Scaling and root planing Scaling and root planing (SRP) For the control group, conventional scaling and root planning (SRP) only."
