Which flap design provides best apical access with least soft tissue reflection?
Show answer and explanation
Correct answer: B. Semilunar
The semilunar (curved) flap creates a convex incision over the root apex, providing direct apical access with minimal reflection. It is preferred for apicoectomies and removal of root tips or small periapical cysts, and preserves attached gingiva.
