0.2% Chlorhexidine vs MicroRepair ABX in Gingivitis

"At baseline (T0), participants receive clinical assessments, oral hygiene instruction, and begin a 14-day home regimen with MicroRepair® ABX mouthwash, which contains zinc-hydroxyapatite microcrystals and antibacterial agents (cetylpyridinium chloride, magnolol, honokiol). The mouthwash is used twice daily (10 mL for 30 seconds) after toothbrushing, without rinsing, and participants avoid food or drink for 1 hour. All participants use a sodium lauryl sulfate (SLS)-free toothpaste (Biorepair®) throughout the study.~At 1 month (T1), participants undergo professional supragingival prophylaxis following the Guided Biofilm Therapy (GBT) protocol, which includes plaque disclosure, ultrasonic debridement with an EMS Piezon piezoelectric device, and air-polishing with glycine powder.~At 3 months (T2) and 6 months (T3), additional GBT sessions and a repeated 14-day mouthwash cycle are performed only if the Full-Mouth Bleeding Score (FMBS) remains greater than 10%."
