Abstract:
This is an extremely rare case of concomitant hypo-hyperdontia with mandibular mesiodens. Concomitant hypo-hyperdontia (CHH) refers to the presence of hypo and hyperdontia in the same patient. Supernumerary teeth may lead to difficulties such as delayed or ectopic eruption of permanent teeth, spacing, malocclusion, cystic lesions, and retained deciduous teeth. The present study describes an unusual case of an eleven-year-old girl with CHH and a medical history of hyperthyroidism. The Cone Beam Computed Topography (CBCT) results revealed thirty-one permanent teeth with a missing mandibular left lateral incisor, eleven deciduous teeth, and eight unerupted supernumerary teeth (four in the maxilla and four in the mandible). This study aims to outline the etiology, complications, diagnosis, and multidisciplinary approach for the management of a case of supernumerary teeth.
