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
