Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • post treatment plaque score

    plaque score based on Loe and Silness 1963. Minimum score is 0. Maximum score is 1. It is a categorical scale of 0 or 1 and is not a continuous scale. 0 is a good outcome and 1 is a poor outcome. Each side of the tooth will be recorded as either a 0 or a 1. It will be added up and averaged out by the number of tooth sides multiple by 100% to get a percentage total score. The higher the percentage, the worser the outcome.

Secondary Outcomes (1)

  • Treatment duration

    1 day

Study Arms (4)

Plaque Disclosed with Air Flow (PDAF)

EXPERIMENTAL

Plaque will be disclosed prior to polishing with the air flow system.

Procedure: Plaque disclosed with air flow

Plaque Disclosed with Rubber Cup (PD-RC)

EXPERIMENTAL

Plaque will be disclosed prior to polishing with the rubber cup and fine grit prophylaxis paste.

Procedure: Plaque disclosed with rubber cup

Non Plaque Disclosed Air Flow (NPD-AF)

EXPERIMENTAL

Air polishing system will be used to remove the plaque

Procedure: Non plaque disclosed air flow

Non Plaque Disclosed Rubber Cup (NPD-RC)

PLACEBO COMPARATOR

Rubber Cup polishing to remove plaque.

Procedure: Non plaque disclosed rubber cup
