What this trial studies

This double-blind, randomized controlled trial at Saidu College of Dentistry will randomize 60 patients with fixed orthodontic appliances to use either 0.12% chlorhexidine or an essential-oil mouthwash (Listerine) for 4 weeks. Gingival Index and Plaque Index scores will be recorded at baseline, 2 weeks, and 4 weeks to compare changes between groups. Eligible participants are adolescents and adults with permanent dentition who meet inclusion criteria and have no systemic illness or contraindications. The trial aims to see if Listerine provides comparable plaque and gingival control to chlorhexidine while producing fewer side effects.

Who should consider this trial

Good fit: Ideal candidates are people aged 13–40 with permanent dentition who are undergoing or have fixed orthodontic appliances and can attend baseline, 2-week, and 4-week visits.

Not a fit: Patients with systemic illnesses, pregnant or lactating women, current tobacco users, those with known mouthwash allergies, or those unable to attend follow-up visits are unlikely to benefit from participating.

Why it matters

Potential benefit: If successful, this could give people with braces an effective mouthwash option that reduces plaque and gum inflammation with fewer side effects than chlorhexidine.

How similar studies have performed: Previous studies have shown chlorhexidine reliably reduces plaque and gingivitis but commonly causes staining and taste changes, while essential-oil mouthwashes like Listerine have demonstrated moderate anti-plaque and anti-inflammatory effects in prior trials.
