Developmental Disturbance of a Maxillary Permanent Lateral Incisor Following Trauma at the Age of 16 Months: A 6-Year Follow-Up

Abstract

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.

A 14-Year Follow-Up Study of Sequelae in Primary Teeth and Permanent Successors After Dental Trauma

“…Careful clinical and radiographic examinations at regular intervals are important to follow PT and PS. The consequences on the successor tooth may not be easy to predict or may not be evident until the tooth erupts [14]. In this context, the present study was conducted to evaluate the presence of sequelae in primary teeth and their permanent successors, as well as the associations between TDI and the presence of sequelae through a 14-years follow-up study.…”
