What defines a Preventive Resin Restoration (PRR)?

A Preventive Resin Restoration (PRR) is defined as a minimally invasive procedure designed specifically to address small carious lesions. This approach aims to conserve as much healthy tooth structure as possible while effectively treating the affected area. The process typically involves the careful removal of decayed material and the application of a resin material to restore the tooth. This technique is preferred because it minimizes the need for extensive preparation or drilling, focusing on prevention and early intervention.

In contrast, full coverage procedures for serious caries typically involve more invasive techniques, which are not characteristic of PRRs. Elective cosmetic procedures generally focus on aesthetics rather than decay management, and PRRs are specifically aimed at preventing further decay rather than just improving appearance. Additionally, the requirement for extensive drilling would not apply to PRR since its purpose is to minimize tooth structure removal, aligning with the principles of minimally invasive dentistry.
