Case report: treatment of caries perforation in the furcal region

One of the major factors responsible for failure in treatment is perforation and different studies have shown that furcal perforation will result in destruction of tooth supporting tissues and if not treated, may result in tooth loss. Different materials have been introduced for perforation treatment, such as Cavit, Zinc Oxide Eugenol, Calcium Hydroxide, Amalgam and MTA. Today, MTA (first introduced by Torabinejad in 1993 as a root end filling material) is the first choice for treating perforations, due to its excellent sealing ability and biocompatibility. In this report, we describe the treatment with MTA performed for a patient with perforation due to massive dental caries and the results of the treatment. Case Report: The patient was a 19 year old girl with no medical records which came to clinic for treatment of her lower left first molar tooth. The clinical and radiographic investigations showed massive decay in the crown and forcal region of the molar tooth. First, the crown and furcal caries were completely removed. After root treatment with Guta-Percha and AH26 sealer, the perforation was sealed with MTA and temporarily filled and in the next session, the tooth was restored. 6 months later, radiographic investigation was performed to confirm the success of treatment. Perforation in the furcal region, even if it is produced by caries, can be treated using MTA and this material is thought to be the first choice for treating perforations.
