Evaluation of a Novel Dual-Headed Toothbrush Design for Periodontal Health: Split-Mouth Randomized Blind Clinical Trial

A novel toothbrush with a dual-headed design intended to clean both upper and lower buccal/ or upper and lower lingual/ palatal surfaces simultaneously. Participants were instructed to use this toothbrush on one side of the mouth only, twice daily using the Bass brushing technique. This intervention is evaluated for plaque removal efficacy, gingival health, brushing time, and patient comfort

A standard single-headed manual toothbrush used as the active control. Participants used this toothbrush on the other side of the mouth, with the same brushing technique (Bass method), frequency (twice daily). It serves as the comparator for assessing the performance of the dual-headed design.
