What this Trial Is About
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
