A Comparison of the Outcomes of Two Existing Routine Clinical Therapies for Dental Prophylaxis

Background: In most practices, conventional in-office prophylaxis starts immediately with scaling and polishing. Therefore, this project was designed to challenge tradition by comparing plaque removal efficacy of rubber cup and air polishing in two scenarios, one where plaque was disclosed prior to treatment and the other where plaque was not disclosed. Methods: In this randomized, single blind, split-mouth design clinical trial, healthy, non-smoking participants with poor oral hygiene were recruited. Quadrants in each participant were randomly assigned to 4 treatment groups, which were plaque disclosure with rubber cup polishing, no plaque disclosure with rubber cup polishing, plaque disclosure with air polishing, and no plaque disclosure with air polishing. Examiners were calibrated and masked to the treatment rendered in each quadrant. Post treatment satisfaction questionnaires for both participants and operators were completed. Plaque scores for each quadrant and treatment time were the recorded outcome measures.
