ABSTRACT

Isolated bilateral macrodontia of mandibular second premolars is an extremely rare dental anomaly with only 5 cases reported to date. This case report presents clinical and radiographic findings of isolated bilateral macrodontia in a 12-year-old child. The patient was referred to the clinic with local crowding of mandibular posterior teeth. Radiographic findings revealed the presence of impacted macrodont mandibular second premolars and their distinct morphological appearance, characterized by large, multitubercular, molariform crowns, and tapering, single roots. Following surgical removal of the impacted premolars, orthodontic therapy was initiated to correct the malocclusion. Along with the features and treatment of this rare anomaly, this case report also illustrates the benefits, in terms of treatment planning and surgical technique, of supplementing conventional radiography with cone-beam computed tomography to localize the macrodont premolars and accurately establish their relationship with the neighboring roots and anatomic structures.
