What is the definition of dilaceration?
Show answer and explanation
Correct answer: D. Sharp bend or curve in the root of a tooth
- A. Incomplete root formation is called open apex, immature apex, or blunderbuss apex — not dilaceration.
- B. Extra roots are called supernumerary roots or radiculomegaly — not dilaceration.
- C. Root shortening from resorption is not dilaceration. Dilaceration specifically refers to the angular bend in the root.
- D. Dilaceration is defined as a SHARP BEND OR ANGULATION in the root or crown of a tooth, typically resulting from trauma during tooth development that displaces the calcified portion while the rest of the tooth continues to develop in a different direction. The resulting abnormal curvature can complicate root canal treatment and extraction.
