What does a tear drop radiolucency indicate?

  1. Dental caries

  2. Periodontal disease

  3. Tooth decay

  4. Vertical root fracture

The correct answer is: Vertical root fracture

A tear drop radiolucency is a triangular radiolucent shaped area in the dental x-ray. This can indicate a vertical root fracture in a tooth. Dental caries, periodontal disease, and tooth decay all present as different shapes on a dental x-ray and would not appear as a tear drop radiolucency. Therefore, D is the correct answer.
