Endodontics · single question
What is the advantage of achieving a straight-line access cavity in endodontics?
Show answer and explanation
Correct answer: D. All of the above
D) All of the above — CORRECT.
Straight-line access (elimination of coronal interferences) in endodontics provides: (1) easier insertion of files without deflection, (2) direct path to the apical third reducing binding, (3) improved tactile sensation, (4) reduced risk of ledging, transportation, or instrument separation. It is a fundamental principle of access cavity preparation.
A) Easy file placement: True but incomplete.
B) Reaching the apical third: True but incomplete.
C) Reducing complications: True but incomplete.
