Evaluation of a Novel Dual-Headed Toothbrush Design for Periodontal Health: Split-Mouth Randomized Blind Clinical Trial
Clinical and Patient-Based Evaluation of a Novel Dual-Headed Toothbrush Design: Split-Mouth Clinical Trial
Dar Al Uloom University
40 participants

INTERVENTIONAL
Conditions
Summary
The goal of this clinical trial is to evaluate the effectiveness and patient satisfaction of a novel dual-headed toothbrush design compared to a conventional single-headed toothbrush in adult dental professionals aged 22-45 years with healthy gingival conditions. The main questions it aims to answer are: Does the dual-headed toothbrush improve plaque removal efficiency compared to a single-headed toothbrush? Does the dual-headed toothbrush enhance brushing comfort, reduce brushing time, and improve user satisfaction? Researchers will compare the side of the mouth (cleaned with a dual-headed toothbrush) with the other side (cleaned with a single-headed toothbrush) in a randomized split-mouth design to see if the novel design leads to superior plaque control and better user experience. Participants will: Receive both toothbrush types (medium bristle) and identical toothpaste Be trained in the Bass brushing technique Use each toothbrush, twice daily, with the assigned toothbrush applied to its designated side of the mouth Complete post-trial questionnaires on comfort, ease of use, and brushing time

Interventions
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.
