Bilateral supplemental maxillary central incisors: a case report

Hyperdontia is a developmental anomaly that is hypothesized to arise from multiple causes. Supernumerary teeth may remain embedded in the alveolar bone or can erupt into the oral cavity. When such teeth remain embedded, they may cause disturbances to developing teeth. Erupted supernumerary teeth can cause aesthetic or functional problems, especially when situated in the maxillary anterior region. Before a definitive diagnosis and treatment plan can be developed, it is essential to clinically and radiographically enumerate and identify supernumerary teeth. Supplemental central incisors are rare and bilateral cases are even rarer: only five cases have been reported in the literature to date. We describe a case of bilateral supplemental maxillary central incisors and discuss the management of supernumerary teeth.
