Dilaceration
Posted on November 14th, 2008 in Definitions
Dilaceration is the anamolie in the tooth shape and its structure and it refers to a sharp bend in the tooth which can be in the crown portion or in the root, making sharp angles at the junction of the crown and root.
It is also described as “Dilaceration is the result of a developmental anomaly in which there has been an abrupt change in the axial inclination between the crown and the root of a tooth”
It occurs as a result of trauma to the predecessors of the permanent teeth, and it is seen that Dilaceration of the root is more common than that of crown.
Etiology: The cause of this anamolie in the shape of the tooth has two main reasons:
- Trauma
- Developmental disturbances
- Developmental Syndromes
Dilaceration is seen in both Permanent and Deciduos teeth equally.

how can we identify the dilaceration clinically with out X-ray?

As i already mentioned in the post Dilaceration of the tooth maybe coronal or root type, and clinically Coronal dilacerations are appreciated more than the root type, Root dilacerations are better left untouched, and the crown type are treated for aesthetic, occlusion, oral hygiene purpose.
The root Dilacerations are considered only in case o extractions where these may cause problems while extraction.

You may want to consider root dilaceration even when not extracting. As the name implies, it is a mangled formation of root, and as with anything that gets mangled, there is often a reason, such as a cyst or other anomaly in the bone. As to detection without x-ray, use your hands to see, develop a feel for what a tooth, held by the crown and feeling the bone surrounding the apical area, feels like when observed passively, as well as actively.
