What should be done if saliva contamination occurs during the etching procedure?

In the etching procedure, if saliva contamination occurs, it is crucial to address the situation properly to ensure the success of the bonding process. Saliva can interfere with the adhesion of dental materials, potentially compromising the quality of the restoration or bonding.

The appropriate action is to repeat all steps and re-etch for an additional time period, typically around 5 seconds. This approach ensures that the enamel or dentin surface is adequately prepared for bonding by removing any contaminants and redistributing the etching material effectively. This thorough process not only enhances bonding but also ensures that the surface is clean and ready for the subsequent application of adhesives or restorative materials.

By addressing saliva contamination in this manner, the dental assistant helps to uphold the quality of the dental work, enhancing both the longevity of the restoration and patient satisfaction.
