摘要

牙髓的微循环系统在维持体内平衡中起着至关重要的作用。透射光体积脉搏波(TLP)是一种检测牙髓血液循环的无创、客观的诊断方法,已在儿科和特殊需要牙科临床应用于牙髓活力测试。由于牙髓包裹在矿化组织中,可见区域波长较短的LED光源由于血红蛋白的高吸收率,适合检测微小的血流变化。本文综述了TLP法血流测量在牙髓诊断中的作用,以及幼龄恒牙发育阶段微循环的相关发现。

The Diagnosis of Dental Pulp of Traumatized Teeth through Pulpal Blood Measurement Using LED
The microcirculatory system of the dental pulp plays an essential role in the maintenance of homeostasis. Transmitted-light plethysmography (TLP) is a non-invasive and objective diagnostic method for detecting blood circulation in the dental pulp, and has been clinically used as a pulp vitality test in pediatric and special-needs dentistry. As the dental pulp is encased in mineralized tissues, LED light sources with shorter wavelengths at visible regions are suitable for detecting minute blood flow changes due to high absorbance by hemoglobin. This review summarizes the role of blood flow measurements using the TLP method for the diagnosis of dental pulp, and findings relevant to microcirculation in the developmental stages of young permanent teeth.
