Powered vs. Manual Toothbrushing in Stage 3-4 Periodontitis

This single-blind, randomized controlled trial evaluates the clinical effectiveness of powered versus manual toothbrushing in patients newly diagnosed with stage 3 or 4 periodontitis. Participants are randomly assigned to one of two groups: powered toothbrush (Oral-B iO6) or manual toothbrush (TePe Select Soft). All participants receive standardized oral hygiene instructions and are instructed to brush twice daily for a minimum of two minutes. Manual brush users are required to use a smartphone app to monitor and record brushing duration. The use of adjunctive oral hygiene aids, such as mouthwash or interdental cleaners, is restricted throughout the study period. The primary clinical outcomes are full-mouth bleeding score (FMBS) and full-mouth plaque score (FMPS), measured at baseline and at follow-ups of 7 days, 1 month, 3 months, and 6 months.
