Post-obturation radiographs should be taken to assess which aspect?

• A. Post-obturation radiographs should be taken to assess fill length and adaptation.
• B. Post-obturation radiographs are unnecessary.
• C. Radiographs after obturation should be avoided due to radiation.
• D. Only occlusal radiographs are needed after obturation.

Answer: (A)

After obturation, radiographs are used to verify the quality of the fill by checking two key factors: fill length and adaptation. The image should show the obturation material extending to near the apical constriction, typically within about 0–2 mm of the radiographic apex, and it should follow the canal walls without voids or gaps. This confirms a proper seal and helps identify underfilling, overfilling, or voids that could compromise the treatment. Radiographs are not unnecessary; they are a necessary part of quality control, taken with proper shielding and minimized exposure. An occlusal radiograph alone wouldn’t provide the needed information about the canal length and internal adaptation.
