Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.
