Management of progressive apical root resorption 13 years after dental trauma and primary endodontic treatment

Abstract

Many studies have focused on the search for a restorative material with good sealing properties and biocompatibility for treatment of teeth with open apices and necrotic pulps, which can result from periradicular disease and root resorption. Mineral trioxide aggregate (MTA) has exhibited promising clinical results in retrograde fillings and pulpotomies as well as for treatment of root perforations, root resorptions, incomplete root formations, and pulpal necrosis. This case report describes the management of a progressive apical root resorption in a previously traumatized tooth that had been endodontically treated. Five years of clinical and radiographic follow-up demonstrated the clinical efficacy of MTA in limiting the inflammatory resorptive process and promoting apexification and regeneration of periradicular tissue.
