Pericoronal radiolucency associated with an impacted premolar tooth

Abstract

The mandibular second premolar is highly variable developmentally. Agenesis, abnormal tooth germ position, distal inclination of the developing tooth, and impaction are among the reported developmental anomalies. Detection of pathologic lesions associated with an impacted tooth usually requires removal of the tooth and the lesion. The purpose of the present report was to describe the radiographic and histopathologic features of a case of pericoronal radiolucency associated with an impacted mandibular premolar tooth.
