In endodontic post-placement radiographs, what indicates proper seating and adaptation?

• A. Absence of gaps between post and canal walls
• B. Fracture line in the tooth around the post
• C. Radiolucent halo around the post
• D. Absence of gaps between the post and canal walls and preserved tooth structure around the post

Answer: (D)

In endodontic post-placement radiographs, proper seating and adaptation are shown by the post fitting tightly against the canal walls without any radiolucent gaps, and by preserving the surrounding tooth structure around the post. This combination means the post is well-seated and the cement is encasing the post smoothly, providing a solid seal and maintaining dentin support. If gaps were present, you’d see radiolucent areas indicating poor adaptation and potential leakage. If a radiolucent halo appeared around the post, that would suggest voids or poor cement fill. A fracture line would indicate structural damage.
