The purpose of this study was to evaluate the effect of labial and palatinal gingiva on laser Doppler pulpal blood flow measurements. Twenty upper central incisor teeth determined to be vital from 20 volunteers were included into the study. To stabilize the probe, a laboratory-made acrylic splint positioned the probe labially on the cervical third of the tooth crown. We collected measurements without any gingival covering, and under three conditions: after application of an opaque paste on the labial gingiva, the palatal gingiva, or both the labial and palatal gingiva. The measurement values decreased 46% when there was opaque paste on labial gingiva, 10% on palatinal gingiva, and 63% on both. The decrease in the values when there was an opaque paste on palatinal gingiva was not statistically significant (p > 0.05). The differences between all other groups were statistically significant (p < 0.05). In these measurements, the contribution of labial gingiva to laser Doppler pulpal blood flow measurements is more than that of palatinal gingiva.
本研究的目的是评估唇侧和腭侧牙龈对激光多普勒牙髓血流测量的影响。从20名志愿者中选取20颗确定为活髓的上颌中切牙纳入研究。为了固定探头，用实验室制作的丙烯酸夹板将探头唇侧放置在牙冠的颈三分之一处。我们在没有任何牙龈覆盖的情况下以及在三种条件下进行测量：在唇侧牙龈、腭侧牙龈或唇侧和腭侧牙龈上涂抹不透明糊剂后。当唇侧牙龈有不透明糊剂时，测量值下降46%，腭侧牙龈下降10%，两者都有时下降63%。腭侧牙龈有不透明糊剂时测量值的下降无统计学意义（p>0.05）。所有其他组之间的差异有统计学意义（p<0.05）。在这些测量中，唇侧牙龈对激光多普勒牙髓血流测量的贡献大于腭侧牙龈。
