Case Discussion

Dilaceration is an abnormal angulation or bend in the root and less frequently, the crown of a tooth. Most cases are idiopathic. In limited cases, injury was the first reason.

Trauma can displace the calcified portion of tooth germ so that the non-calcified part of the tooth is formed at an abnormal angle.
