How is the effectiveness of coronal polishing assessed?

The effectiveness of coronal polishing is primarily assessed by observing a smooth, shiny enamel surface after the procedure. This assessment is crucial because the main objective of coronal polishing is to remove plaque and stains from the tooth surface while leaving the enamel intact and polished. A smooth, shiny surface indicates that the polishing technique was performed correctly, and that biofilm and extrinsic stains were effectively removed, which enhances the aesthetic appearance of the teeth and contributes to overall oral health.

The other options do not provide a direct measure of polishing effectiveness. For example, measuring the amount of paste used does not correlate with the quality of the polishing done; it could vary based on technique rather than effectiveness. The number of teeth polished is also not a measure of quality, as a higher quantity does not guarantee a better outcome if the technique was poor. Lastly, while patient feedback can be valuable, it is subjective and may not always accurately reflect the technical success of the procedure. Therefore, the visual assessment of the smoothness and shine of the enamel surface is the most reliable indicator of effective coronal polishing.
