Rare simultaneous occurrence of internal root resorption, external apical resorption, and open apex: Management with 2 years follow-up

Abstract

Root resorption of the tooth may be a pathologic or physiologic process resulting in loss of root dentin and cementum. Broadly, it can be of two types – external and internal root resorption. The location of these resorptions can vary from cervical to apical region. Most often, the etiology of it may attribute to some kind of traumatic injuries. External apical resorption, if left untreated for a long period, may result in an open apex with the loss of normal apical constriction and this poses a problem while obturation due to the lack of apical stop. The case becomes of a big concern when such resorptions occur simultaneously along with open apex as these may produce difficulties while managing. Therefore, the objective of the present article is to discuss the root resorption and management of a rare case involving maxillary central incisor with internal root resorption, external apical resorption, and open apex with 2 years follow-up.
