What this trial studies

This study investigates the effects of three polishing methods—bristle brush, rubber cup, and air polishing—on the surface roughness of scaled human teeth. By using a randomized controlled trial design, 56 extracted teeth will be divided into four groups, including a control group with no polishing. The study aims to determine which polishing technique is most effective in minimizing tooth roughness and preventing plaque accumulation, thereby contributing to better oral health practices. Surface roughness will be analyzed using a Scanning Electron Microscope (SEM) to provide precise measurements.

Who should consider this trial

Good fit: Ideal candidates for this study are individuals with extracted human teeth that have intact surfaces and are aged 18 years or older.

Not a fit: Patients with systemic diseases, significant dental defects, or those who have had recent dental polishing may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved dental polishing techniques that enhance oral health by reducing plaque accumulation.

How similar studies have performed: While various studies have explored polishing techniques, this study aims to address inconsistencies in findings and focuses specifically on human teeth, making it a novel approach.

Eligibility criteria
