432 - Early Extraction of Impacted Mesiodens in a Pediatric Patient

Abstract: Reviglio, A. University of Nevada Las Vegas, Las Vegas, NV.

Introduction: Mesiodens are the most common supernumerary teeth and are typically located in the maxillary midline. They may interfere with the eruption of permanent maxillary incisors, leading to delayed eruption, displacement, or malocclusion. Early diagnosis and appropriate management are important to prevent potential complications.

Case Report: A 7-year-old male presented with delayed eruption of the right permanent maxillary central incisor and referral for extraction. The patient’s medical history was significant for attention-deficit/hyperactivity disorder (ADHD). The patient is currently taking Risperidone to manage ADHD. The patient has no reported drug allergies. Clinical examination revealed no signs of infection, swelling, or history of trauma. Radiographic evaluation using periapical radiography and cone-beam computed tomography (CBCT) identified an impacted, conical supernumerary tooth consistent with a mesiodens. It was located palatally, in the maxillary midline between the developing permanent maxillary central incisors, obstructing the normal eruption pathway. Surgical extraction of the mesiodens was performed under local anesthesia with appropriate behavioral guidance techniques. The procedure was completed without complications.
