###Human: Kindly advice about the possibility sinus exposure on my X-ray taken to view third molar. ###Assistant: Hello. Yes, you have impacted molars (attachment removed to protect patient identity). One of the upper molars has proximity with sinus, but it will not cause any complication or sinus exposure. Sinus exposures are a complication to disimpaction, but it is not necessary to happen in your case. You need to go ahead and get them removed. The possibility is least as per the radiographic relation between the sinus and upper molars.
