Nonsyndromic multiple mandibular supernumerary premolars: a case report.

Supernumerary teeth are generally asymptomatic and may not become visible radiographically until a patient's normal teeth have erupted. Moreover, diagnosing, treating, and following up supernumerary teeth appropriately with radiographic images is important. In this case report, we present radiographic images, including three-dimensional computerized tomography films, of a 13-year-old patient with four nonsyndromic mandibular supernumerary premolars, and the surgical treatment.
