A 3 year and 8 months old Chinese boy was referred for a consultation regarding his missing maxillary anterior teeth. He had a history of trauma to his primary maxillary anterior teeth due to a fall at the age of 16 months. Clinical examination of the patient indicated multiple carious lesions and inadequate oral hygiene. Radiographic examination revealed intrusion of the primary left lateral incisor, with evidence of damage to the permanent tooth germ. Subsequently, the patient was followed-up for almost six years during which his permanent maxillary left lateral incisor erupted exhibiting an unusual morphology. Clinically enamel hypoplasia and radiographically dens invaginatus were evident in affected tooth.
