Dilaceration is an abnormal bend in the root or crown of a tooth that is most commonly seen in the permanent maxillary incisors and premolars. It is usually caused by trauma during tooth development. Crown dilaceration can prevent eruption or cause teeth to erupt in abnormal positions, while root dilaceration may complicate procedures like extraction or endodontic treatment and be detected radiographically as a bull's eye appearance. Minor dilaceration requires no treatment but severely deformed teeth may need extraction.

3. DILACERATION

5. Dilaceration is an abnormal bend in the root or crown of a tooth
❑The root is affected most frequently
❑most often in the permanent dentition and frequently
affects the maxillary incisors AND maxillary premolars .
CAUSES - ,.
• Trauma during tooth development, such as avulsion or
intrusion of an overlying deciduous tooth.
• An adjacent anatomic structure, cyst, or tumors
• Retained primary tooth.
• the presence of supernumerary tooth or teeth.

8. • Root dilaceration is not
detected clinically
• •
• Crown dilaceration seen
as angular distortion
○May prevent eruption of tooth
○Those that erupt are often in labial or lingual position

9. • when the roots are dilacerated buccally (labially) or lingually, the central x ray passes approximately
parallel with the deflected portion of the root, and the apical end of the root may have the appearance of a
circular or oval radiopaque area with a central radiolucency (the apical foramen and root canal), giving the
appearance of a “bull's eye.” The PDL space around this dilacerated portion may be seen as a
radiolucent halo encircling the radiopaque area
Diagnosed radiographically
BUT
SOMETIMES
If the roots dilacerate mesially or distally, the condition is clearly apparent on an X-RAY

11. Management
• Minor dilaceration requires no treatment.
•Dilacerated root may complicate
extraction, endodontic treatment, orthodontic treatment,
or preclude use as abutment
••
•Dilacerated crown may be restored with full-coverage crown to improve
esthetics and function
••
•Grossly deformed teeth may require extraction
