This week I have a case of dilaceration (an abnormal curvature of a root or roots). It is important to note that a dilaceration is an ABNORMAL curvature and not to be confused with roots that normally have a slight curve to them (such as the mesio-buccal and disto-buccal roots of a maxillary first molar). Dilacerations are important to note before beginning endodontic treatment. If it is not noted before, it can make for quite a difficult procedure. This case is a dilacerated maxillary canine in the apical third of the root.
