Abstract

Dental pulpal and mandibular marrow vascular pressures were studied with a tonometric method under conditions of autoperfusion and step flow controlled perfusion. The tonometric pulpal and marrow pressures averaged 17 +/- 5 mm Hg and 20 +/- 6 mm Hg, respectively. The venous end pressure was 16 +/- 8 mm Hg at a perfusion pressure of 156 +/- 28 mm Hg. The tonometric pulpal pressures were lower and were less variable than the comparable canulation pulpal pressures.

摘要

采用眼压测量法，在自身灌注和步进流控制灌注条件下，对牙髓和下颌骨髓血管压力进行了研究。眼压测量法测得的牙髓和骨髓压力平均分别为17±5mmHg和20±6mmHg。在灌注压力为156±28mmHg时，静脉端压力为16±8mmHg。眼压测量法测得的牙髓压力比通过插管法测得的牙髓压力更低且变化更小。
