In mouth preparation for RPD, what should be done if there is dentine exposure?

When dentine exposure occurs during mouth preparation for a removable partial denture (RPD), it is essential to restore the exposed area. The presence of exposed dentine can lead to sensitivity, a higher risk of caries, and complications in the longevity and stability of the dental restoration.

Restoring the dentine ensures that the tooth structure is protected from thermal, chemical, and bacterial attacks. This restorative process often involves applying a suitable dental material to cover the exposed dentine, ideally restoring the tooth's integrity and function. By addressing the exposure before proceeding with further steps in RPD preparation, the overall health of the affected tooth is preserved, which is crucial for the success of the entire prosthetic treatment.

While options related to gingival health or modifications to preparation steps may seem relevant, they do not address the immediate need to protect the exposed dentine, making restoration the necessary first step in this scenario.
