PREVENTIVE RESIN RESTORATIONS (PRR)
Many permanent and baby teeth have deep grooves that develop small dental caries (cavities). Ideal treatment is a conservative white filling that allows the restoration of the cavity area and also seals the remaining deep grooves to prevent new cavities from forming. Differentiating between staining which is not a cavity and a true cavity in a groove requires clinical experience and sound diagnostic skills.
This document was prepared to help our patients better understand the details of this procedure. We will continue to provide the highest quality and standards of dental care. We welcome your questions about this procedure or any others which might be of concern to you.
DIAGNOSIS - The photo on the left shows a new cavity and the one on the right shows a cavity under an existing filling. Both require careful removal of caries which will be achieved by drilling the tooth structure (left) or existing filling (right).The red circles outline the location of cavities that were diagnosed by your dentist during careful examination, black arrows show the point where cavity originated.
REMOVING THE CAVITY/DRILLING - The first step requires the use of a dental drill to reveal the full extent of the cavity which is usually larger than the point of origin on the cavity shown in the first set of photos. The depth of the cavity and patient comfort will determine whether or not there is a need for local anesthesia (freezing). Most of these cavities can be fixed without freezing if detected early enough.
COMPLETE REMOVAL OF CAVITY - These photos reveal complete removal of the cavities. As seen, the extent of the cavity in most cases is larger than the initial point of origin. The grooves that don’t have cavities are also included in the final preparation which would prevent any new cavities. At this stage the tooth will be treated with several steps of cleaning and bonding in preparation for the white filling.
DIFFERENCE BETWEEN A PRR AND A SEALENT - The photos show the completed white filling after polishing. There are many differences between this procedure and a “sealant”. Sealants are done on teeth with no cavities in which drilling and bonding of a white filling is not required. Sealants are preventive procedures performed at a young age before cavities develop in the grooves of the teeth.
Case 2 - (1) Existing failing Silver Filling
(3) More necessary cleaning of tooth structure
