For managing a remaining root piece from a mandibular premolar during extraction, the MOST appropriate surgical approach is:

Correct answer: C. Buccal flap elevated with bone removal to improve access, then retrieve with root pick

• A. Buccal and lingual troughing without flap elevation is less controlled than a full-thickness flap approach.
• B. Blind probing without flap risks root displacement into the submandibular space or inferior alveolar nerve damage.
• C. Correct. For a retained root piece of a mandibular premolar, the most appropriate and controlled approach is: elevate a BUCCAL FLAP (full-thickness), remove a minimal amount of bone to visualize and access the root tip, then retrieve with a root pick or elevator. This provides direct visualization and avoids inadvertent injury to adjacent structures.
• D. A mesial/distal trough without a flap limits visibility and increases risk of root displacement.
