Treatment of Internal Resorption with Mineral Trioxide Aggregates: A Case Report

Abstract

Tooth resorption is a common sequel which follows injuries or irritation to the periodontal ligament and/or tooth pulp. The course of tooth resorption involves an elaborate interaction among inflammatory cells, resorbing cells, and hard tissue structures. The key cells which are involved in resorption are multi–nucleated giant cells. Internal root resorptions are usually non–symptomatic and they are discovered occasionally through periapical radiographs, which reveal very defined and regular outlines. Many techniques and materials have been used to fill internal resorptive defects. Among them, Mineral Trioxide Aggregates (MTAs) have satisfactory properties, which include: biocompatibility, a favourable sealing ability, mechanical strength and a capacity to promote a periradicular tissue healing. Thus, a Mineral Trioxide Aggregate (MTA) repair of a maxillary left central incisor tooth with an inflammatory resorptive defect, in the middle third of the root canal, has been reported here.
