title: Turner's tooth with unique radiographic presentation: a case report.
abstract: Hypoplasia--the result of a disruption in the enamel matrix formation process--causes a defect in the quality and thickness of enamel. Enamel formation is a complex and highly regulated process. Enamel defects have been associated with a broad spectrum of etiologies, including genetic, epigenetic, systemic, local, and environmental factors. An enamel defect in the permanent teeth caused by periapical inflammatory disease in the overlying primary tooth is referred to as Turner's tooth (also known as Turner's hypoplasia). This article presents a case of Turner's hypoplasia of the first mandibular premolar, with an unusual radiographic presentation.
