Exclusion of infected root tips, dentinal debris, and inflammatory tissue from the maxillary sinus during endodontic surgery is imperative. A simple technique for preventing accidental root tip intrusion into the maxillary sinus using a 6-0 suture and needle and a hole prepared in the root tip with a #2 round bur prior to apicoectomy is presented.
在牙髓手术过程中，将感染的根尖、牙本质碎屑和炎性组织与上颌窦隔离开来至关重要。本文介绍了一种简单的技术，即在根尖切除术之前，使用6-0缝线和缝针，并使用#2圆钻在根尖制备一个孔，以防止根尖意外侵入上颌窦。
