Dual-headed versus single-headed toothbrush for improved plaque control
Clinical and Patient-Based Evaluation of a Novel Dual-Headed Toothbrush Design: Split-Mouth Clinical Trial
This trial will test whether a dual-headed toothbrush cleans plaque more effectively, feels more comfortable, and saves brushing time for adult dental professionals aged 22–45.

What this trial studies
This randomized split-mouth blind trial compares a novel dual-headed manual toothbrush with a conventional single-headed manual toothbrush in adult dental professionals. Each participant uses one brush on the left side and the other on the right side after training in the Bass technique, with identical medium-bristle brushes and toothpaste provided. Outcomes include objective plaque removal measures and participant-reported comfort, maneuverability, and brushing time collected via structured questionnaires. The within-subject design minimizes variability from personal hygiene habits and technique.
Who should consider this trial
Good fit: Ideal candidates are right-handed dental professionals aged about 22–45 with at least 26 natural teeth, mild-to-moderate plaque (PI ≥ 1), good general health, and no systemic conditions affecting oral hygiene.
Not a fit: People with active periodontal disease, orthodontic appliances, recent oral surgery, smokers, or those unable to attend the on-site visits are unlikely to benefit from this protocol.
Why it matters
Potential benefit: If successful, the dual-headed design could improve plaque removal while reducing brushing time and increasing user comfort, potentially improving daily oral hygiene adherence.
How similar studies have performed: Previous small-scale or prototype studies of alternative toothbrush geometries have shown mixed or limited evidence, so this dual-headed design remains relatively novel and not conclusively proven.
