title: Orthodontic therapy in patients with pericoronal hamartoma.
abstract: Pericoronal lesions are undesirable for dental eruption, and they are always associated with unerupted teeth. Pericoronal lesions are common and are usually treated by extraction of the permanent tooth. Pericoronal hamartoma is a special type of pericoronal lesion, and little information about it is available in the orthodontic literature. This report presents a patient with pericoronal hamartoma on the mandibular left permanent first molar who had orthodontic treatment. Because of the similarity of the radiographic radiolucency of pericoronal hamartoma and other lesions, a differential diagnosis must be made to avoid extraction of permanent teeth.
