目的是检查短暂侵入力对人牙髓血流（PBF）的影响。对 17 名具有临床健康牙冠和牙周组织的参与者的 17 颗重要的左上中切牙进行了激光多普勒血流测量。对受检牙齿的切缘施加短暂的侵入力（0.5、1.5 N；持续20秒），同时测量牙齿的根尖位移和PBF。在检查牙齿上使用和不使用不透明橡皮障的情况下进行记录。无论是否有大坝，侵入力都会显着降低 PBF 通量（P < 0.05，弗里德曼分析）。结果表明瞬时心尖位移可以降低 PBF。 (C) 2001 Elsevier Science Ltd. 保留所有权利。
The purpose was to examine the effect of brief intrusive forces on human pulpal blood flow (PBF). Laser Doppler flowmetric measurements were made from 17 vital upper left central incisors of 17 participants who had clinically healthy tooth crowns and periodontal tissues. Brief intrusive forces (0.5, 1.5 N; duration 20 s) were applied to the incisal edges of the examined teeth, and apical displacement of the teeth and the PBF were measured simultaneously. Recordings were made with and without an opaque rubber dam applied to the examined teeth. Intrusive force significantly reduced PBF flux both with and without the dam (P < 0.05, Friedman analysis). The results indicate that transient apical displacement can reduce PBF. (C) 2001 Elsevier Science Ltd. All rights reserved.
