During extraction of maxillary 2nd molar, cortical plates fracture and there is an oro-antral communication. What do you do?

Correct answer: B. Primary closure and refer to oral surgeon

• A. Simply extracting more molars does not address the existing communication.
• B. Correct. Attempt primary closure of the oro-antral communication and refer to an oral surgeon for further management/monitoring, given the complexity and risk of sinus complications.
• C. Primary closure alone without appropriate referral/follow-up may be insufficient if the communication is large or complicated, warranting specialist involvement.
