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.

Detailed description

Tooth surface roughness influences plaque retention and periodontal health. Polishing after scaling helps smoothen enamel surfaces, reducing bacterial adhesion. While various studies have assessed polishing techniques, there are inconsistencies in findings, particularly regarding air polishing vs. rubber cup polishing. Additionally, most studies focus on bovine teeth or indirect restorative materials rather than extracted human teeth. Using a randomized controlled trial (RCT) design, 56 extracted teeth will be divided into four groups: a control group (no polishing) and three experimental groups subjected to different polishing techniques. Surface roughness will be analyzed using a Scanning Electron Microscope (SEM). This study aims to fill these research gaps and provide region-specific data by determining 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

Interventions

Type	Name	Description
PROCEDURE	Bristle Brush Polishing	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	Rubber Cup Polishing	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	Air Polishing	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	Ultrasonic Scaling	Teeth in the control group will undergo ultrasonic scaling only, with no additional polishing procedures.
