Role of cone-beam computed tomography for the diagnosis of the labially inverted impaction of maxillary central incisor

Abstract

Impaction of permanent maxillary central incisor is very rare. Inverted impaction of the maxillary central incisor is even more uncommon. Impacted central incisor can cause esthetic concern to the patient or can be associated with the dentigerous cyst. Conventional radiographs including intraoral periapical radiograph, occlusal radiograph, and pantomograph are most commonly advised for the diagnosis and evaluating the location of the impacted tooth. Two-dimensional imaging modality may not exactly locate and evaluate the tooth, root dilacerations, and effect on the surrounding structures. Cone-beam computed tomography (CBCT) will assist in locating the tooth and evaluating the morphology. Inverted impaction of the central incisor has been reported as a rare entity in literature. This article discusses the case report along with the role of CBCT in diagnosis and evaluation of the labially inverted impaction of the central incisor.
