What is the primary corrective treatment recommended when dentine exposure is noted during RPD mouth preparation?

When dentine exposure is noted during the preparation of a removable partial denture (RPD), the primary corrective treatment recommended is to apply a restoration. This is because exposed dentine can lead to increased sensitivity and a higher risk of decay or other complications. By placing a restoration over the exposed dentine, you can provide a protective layer that seals the dentine tubules, thereby reducing sensitivity and protecting the tooth structure from further damage.

Using a restoration also ensures that the tooth remains strong and is better able to support the RPD, promoting overall oral health and comfort for the patient. This approach aligns with the best practices for maintaining tooth integrity and function throughout the RPD treatment process.

In contrast, proceeding without changes could result in long-term issues with sensitivity and tooth health. A temporary filling may only provide a short-term solution and not fully address the underlying problem. Adjusting the framework might help with fit issues, but it would not resolve the concern with exposed dentine, which is more critical to address to ensure the success of the RPD.
