What is the BEST method to assess progress in Root Canal Treatment (RCT)?
Show answer and explanation
Correct answer: B. Take preoperative and postoperative periapical radiographs and clinically examine
✓ B) Pre-op and post-op PAs with clinical examination is correct.
The standard of care for assessing RCT progress involves comparing preoperative and postoperative periapical radiographs combined with clinical evaluation (symptom resolution, percussion, palpation tests). CBCT provides more detail but is reserved for complex anatomical cases or diagnosis of failed treatment — it is not the routine follow-up method due to higher radiation dose and cost.
