Abstract:

Anterior dilaceration is one of the common sequelae after the dental trauma of primary teeth while the permanent anterior teeth are still growing. It is characterized by displacement of a tooth root from its normal alignment and diagnosed via radiographic data. With the improvement of examination methods, such as cone beam computed tomography, the disease has been detected more frequently and received increasing clinical attention. New thoughts and treatment methods have been reported. The treatment method depends on the degree of dilaceration, which varies among different individuals and requires accurate assessment. This article reviews the etiology, epidemiology, features, imaging evaluation, diagnostic methods, and treatment methods of anterior dilaceration to provide clinical reference.

Key words: dilaceration, anterior teeth, cone beam computed tomography, diagnosis, surgery, orthodontic traction
