What is the PRIMARY goal of endodontic access cavity preparation?

  1. Preserve maximum coronal tooth structure at all costs
  2. Remove entire chamber roof and all pulp tissue
  3. Maximize the size of the access opening
  4. Achieve straight-line access to root canal orifices
Show answer and explanation

Correct answer: D. Achieve straight-line access to root canal orifices

PRIMARY GOAL = STRAIGHT-LINE ACCESS to root canal orifices and apical foramen. This allows instruments to be introduced without deflection by cavity walls. Complete roof removal is necessary but is the means to achieving straight-line access.
