After removing caries from a tooth preparation, what is the recommended action?

After removing caries from a tooth preparation, the recommended action involves ensuring that the tooth is properly protected before any final restoration is placed. When carious tissue is excavated, the underlying tooth structure is often fragile and can be susceptible to further damage or bacteria. Leaving the area exposed would increase the risk of contamination and further decay.

Restoring with a temporary filling can sometimes be indicated in specific situations, such as when a patient needs to return for further treatment or if immediate restoration is not feasible. However, it is generally not the best practice immediately after caries removal unless explicitly required.

The option of restoring with a cement base might have some merit depending on the situation, but it is often part of the final restoration process rather than the immediate step following carious removal. Therefore, when considering the best practice to ensure the health of the tooth and the success of any subsequent procedures, the chosen option reflects the understanding that immediate and appropriate subsequent management is essential.
