Incision for root tip resection, Dental Education Lecture

如以前介绍（一，二）右下第一磨牙近中根尖阴影根管治疗后逐渐增大（图一*），最后病人同意做根切，术前颊侧观显示近中根尖处肿胀（图二*），前庭沟挺深的，暴露可能不错（金杭晴理论），但如何做切口呢？根尖附近半月形切口（图三），还是牙龈沟切口附加斜形切口（图四）？结果

Dear Dr. Jin:

Thank you very much for sending this message to me before seeing the patient. In fact I did not check it until surgery (apicoectomy). Do not feel bad providing advice not consistent with that of Dr. Fang.

Probably due to our similar background (oral surgery), I chose surgical mode. I particularly like your idea: 根切的关键在于前庭沟浅还是深，深好做，因为暴露好。In fact the vestibule is deep in this case as will be shown soon in my web. What incision should I make, gingival sulcus or apical semilunar, for the best exposure? Xin Fri, 3 May 2013 18:22

Dear Dr. Wei: 我喜欢gingival sulcus incision, apical semilunar 视野太小。我不会生气的，只不过和方老师开个玩笑。等看你的照片。请告知你们的阿拉斯加旅行计划，看我们能不能一起去。很愿意与你交流，因为你的"open, frank & even"。杭晴 Friday, May 3, 2013 11:49 PM

We must be identical twins. I happened to use gingival sulcus incision with the same reason as yours. Please go to my web, Professionals, Classmates, under Endo column, open Recurrent apical periodontitis 2-4 for most of intraop photos. Thanks, everybody. I am sorry that it is too late for the last session. See you tomorrow.
