How should green chromogenic bacterial stains be treated prior to coronal polishing?

The treatment for green chromogenic bacterial stains prior to coronal polishing involves using a mixture of 3% hydrogen peroxide and water. This method is effective because hydrogen peroxide has strong oxidizing properties that can help to break down the pigments responsible for the coloration. It acts on the bacterial biofilm and stains, making them easier to remove during the polishing process.

While other treatments may have their own benefits, they do not specifically target the chromogenic stains as effectively as the hydrogen peroxide solution. For instance, a saltwater rinse may aid in overall oral hygiene but lacks the necessary chemical reaction to reduce stain visibility. A firm abrasive paste could potentially remove other types of stains but may not have the same chemical action against green chromogenic bacteria. Likewise, fluoride gel is primarily used for remineralization and cavity prevention rather than stain removal.

In summary, using a mixture of 3% hydrogen peroxide and water specifically addresses the staining while preparing the tooth surface for effective coronal polishing, making it the preferred method.
