A case of dilaceration of a permanent tooth resulting from trauma to the preceding primary tooth

Background

Trauma to primary teeth can cause dilaceration of permanent teeth.

Case presentation

A boy aged 14 years 6 months at initial presentation had a history of dental trauma at age 4 years. Radiography revealed significant dilaceration and impaction of the maxillary left central incisor, and preservation of the tooth was judged to be infeasible. The necessity of extracting the maxillary left central incisor was supported by examination using the latest digital technology.
