Dilaceration is defined as

Dilaceration is defined as

• A. Fusion of two teeth
• B. Abnormal curve of the tooth root
• C. External root resorption
• D. Pulp necrosis

Answer: (B)

Dilaceration is an abnormal bend or curvature in a tooth, most often in the root, resulting from trauma to the developing tooth. This sharp bend shows up on radiographs as a distinct kink along the root axis and can complicate procedures like root canal treatment or extraction because instruments or forces don’t follow the usual straight path. The other options describe different conditions: fusion of teeth means two tooth buds unite into one tooth, external root resorption is loss of outer root structure, and pulp necrosis is death of the tooth’s pulp tissue. The characteristic feature here is the abnormal curvature of the tooth root.
