Summary

This study looked at 56 extracted human teeth to compare three polishing methods—bristle brush, rubber cup, and air polishing—after scaling. The goal was to see which method makes the tooth surface smoothest, since a smoother surface can help prevent plaque buildup. Researchers used a powerful microscope to measure roughness. The findings could help dentists choose the best polishing technique for cleaner, healthier teeth.
