Brief Summary

This study investigates the effects of three polishing methods using a bristle brush, rubber cup, and air polishing on the surface roughness of scaled human teeth. The study aims to determine which polishing method is most effective in minimizing roughness and preventing plaque accumulation, thus contributing to improved oral health practices.

Conditions

Periodontal Diseases; Tooth Abrasion; Dental Plaque

Keywords

Tooth roughness; Dental polishing; Bristal Brush; Periodontology

Outcome Measures

Primary Outcomes (1)

• Tooth Surface Roughness

  The arithmetic mean roughness (Ra) and root mean square roughness (Rq) of the enamel surface will be measured using Scanning Electron Microscopy (SEM) analysis and ImageJ software. This will assess the effectiveness of different polishing techniques in reducing surface roughness after ultrasonic scaling.

  Immediately after intervention (post-polishing SEM analysis).

Study Arms (4)

Bristle Brush Polishing Group

EXPERIMENTAL

After ultrasonic scaling, teeth will be polished using a bristle brush attached to a low-speed contra-angle handpiece with prophylaxis paste in a circular motion for 10 seconds.

Procedure: Bristle Brush Polishing

Rubber Cup Polishing Group

EXPERIMENTAL

After ultrasonic scaling, teeth will be polished using a rubber cup attached to a low-speed contra-angle handpiece with prophylaxis paste in a circular motion for 10 seconds.

Procedure: Rubber Cup Polishing

Air Polishing Group

EXPERIMENTAL

After ultrasonic scaling, teeth will be polished using sodium bicarbonate air polishing with an air polishing device in a circular motion for 10 seconds.

Procedure: Air Polishing

Control Group

ACTIVE COMPARATOR

Teeth in this group will undergo ultrasonic scaling only, with no additional polishing procedures.

Procedure: Ultrasonic Scaling

Interventions

Ultrasonic Scaling PROCEDURE

Teeth in the control group will undergo ultrasonic scaling only, with no additional polishing procedures.
