Correct answer: D — Sinus precautions and primary closure when indicated

A suspected oroantral communication after maxillary molar extraction should be managed gently with sinus precautions and closure depending on size and clinical circumstances. Vigorous probing or nose blowing can enlarge the communication and force contamination into the sinus. The pearl is to prevent pressure changes and review healing closely.
