Developmental abnormality localized to mandibular left primary incisor

Abstract

Background

Tooth anomalies may occur during the various developmental stages.

Case presentation

A 2Y3M-old Japanese girl came to our clinic. At 1Y8M, the mandibular left primary central incisor had erupted with little or no crown formation, and also showed dysplasia and pulp exposure. Root canal treatment was performed at the first visit, with crown restoration performed with composite resin. The permanent tooth germ showed the same development as the contralateral one.

Conclusion

Symptoms observed in the affected tooth were somewhat similar to those in regional odontodysplasia cases. Careful follow-up examinations until permanent tooth replacement will be necessary.
