An attempt has been made to obtain information about the condition of the pulp of teeth, immediately below the bony incision, made in the lateral antral wall in radical antrotomy, and to investigate the conditions obtaining in the vascular supply of that neighbourhood.THE INVESTIGATION HAS TWO PARTS: (1) Experimental; (2) Clinical.Experimental.-(a) Injections of specimens of the superior maxillae were made with lipiodol, then X-rayed. These showed vascular anastomoses along the antral floor.(b) Sections of the lateral antral wall and floor were cut and stained to show nerves and blood spaces.(c) The external carotid artery was injected with Prussian Blue and the maxilla then removed.(d) Transverse sections of the teeth denervated were cut and their pulps examined. Clinical.-The patients who had been submitted to operation were taken, and their teeth examined by:-(a) Transillumination. (b) Percussion. (c) Thermal tests. (d) Faradic currents. (e) Radiography. From these investigations it appears that the teeth are denervated but not devitalized by the trauma to the lateral antral wall above their apices. Their blood-supply is still present, and probably comes through a collateral anastomosis, along the antral floor and partly through the antral mucosa.
本研究旨在获取根治性上颌窦切开术中，上颌窦外侧壁骨切口正下方牙髓状况的相关信息，并研究该区域的血管供应情况。本研究分为两部分：（1）实验性研究；（2）临床研究。实验性研究：（a）用上颌窦标本进行碘油注射，然后进行X线检查。这些检查显示沿上颌窦底部存在血管吻合。（b）切取上颌窦外侧壁和底部的切片并进行染色，以显示神经和血腔。（c）用普鲁士蓝注射颈外动脉，然后切除上颌骨。（d）切取去神经牙齿的横切片并检查其牙髓。临床研究：选取接受手术的患者，通过以下方式检查其牙齿：（a）透照法。（b）叩诊。（c）温度测试。（d）感应电流。（e）X线摄影。从这些研究中可以看出，牙齿因根尖上方上颌窦外侧壁的创伤而失去神经支配，但并未失活。它们的血液供应仍然存在，可能通过沿上颌窦底部的侧支吻合，部分通过上颌窦黏膜实现。
