| 摘 要： | 介绍了用光电体积描记器、脉冲血氧定量计、激光多普勒流量计等光电技术检测牙髓活力.对于中老年患者,牙龈中的血管比牙髓中发达,牙龈中产生的信号超过了牙髓,所以建立一种有效的光学探测途径相当困难.

| Abstract: | An optical electrical technology method to assess dental pulp vitality is introduced.May be,it is difficult to construct an effective optical probe for middle aged or older patients.In these cases,vascularity in gingiva is much greater than in pulp,the signal resulting from gingiva could be larger.This paper recommends to use photoplethysmography technology,pulse oximeter or laser Doppler flowmeter. |

| Keywords: | dental pulp vitality photoplethysmography |
