The use of resin-ionomer in restorative procedures.
As the average age of the population increases, we are seeing a significant rise in root caries and in the need for restorative procedures associated more often with an older population. This paper describes the subgingival placement of a resin-ionomer for several restorative procedures, including root caries, resorption, endodontic perforation and root fracture. After endodontic therapy, full thickness flaps may be used to gain access to the lesion or root defect. The defects may be prepared with ultrasonic instruments and the preparations treated with a dentin conditioner. The preparations are then washed and lightly air-dried and treated with a dentin bonding agent. A resin-ionomer may then be syringed into the preparations and either light-activated or allowed to undergo a chemical set. No untoward effect has been observed during the time frame of this project. The cases presented indicate that a resin-ionomer may be used as a subgingival restorative and may be placed in lesions originally thought to be unrestorable. Thus, teeth may be saved that were previously designated for extraction.
