Maxillary first molar with 3 roots and close proximity to sinus, how to manage?

Prescribe antibiotics and monitor
Amputate the crown and section the roots
Endodontic treatment only
Immediate extraction of the tooth

The correct answer is: Amputate the crown and section the roots

In this situation, the maxillary first molar has three roots and is very close to the sinus. Due to the proximity to the sinus, preserving the integrity of the sinus is crucial. Prescribing antibiotics and monitoring the situation may not be enough to prevent complications. Endodontic treatment alone may not fully address the issue. Immediate extraction of the tooth may also not be ideal as it can damage the surrounding structures. The best option would be to amputate the crown and section the roots to remove the tooth without damaging the sinus.
