What radiographic feature can indicate root canal calcification?

What radiographic feature can indicate root canal calcification?

• A. Punctate radiopaque fillings within the canal space on a radiograph.
• B. Widened periodontal ligament space around multiple teeth.
• C. Diffuse radiolucent lesion within the canal space.
• D. Radiopaque fillings in the surrounding bone.

Answer: (A)

The main idea is recognizing calcified material inside the tooth’s pulp canal on a radiograph. When the pulp chamber and/or root canal calcifies, mineralized deposits form within the canal space. On radiographs these appear as small, discrete radiopaque spots or “dots” inside the canal, often described as punctate radiopaque findings. These punctate densities are the classic sign that calcification has occurred within the canal. Other findings described would point to different issues: widening of the periodontal ligament space around teeth suggests inflammation or trauma, a diffuse radiolucent area in the canal would imply resorption or a lesion rather than calcification, and radiopaque material in the surrounding bone indicates material outside the canal.
