牙髓活力荧光检测系统的开发研究

针对现行牙髓活力测试方法手段单一、主观性强、患者舒适度差等问题,根据牙髓活力荧光测量理论,提出一种测试系统结构方案.介绍了各硬件功能模块功能和软件流程,并给出了具体的设计参数.系统采用图形界面,触摸屏操作,使用方便,显示直观.进行初步试验,根据仪器显示结果,可明显区分活体牙与死髓牙.光学系统更换不同的滤镜,还可以进行龋齿及牙菌斑等牙病的检测.

Research and Development of Dental Pulp Fluorescence Detect System

For lack of methods in dental pulp vitality detection,large error and pain to the patient using current ways,a new instrument present in this paper,which based on fluorescence detection.The basic function of hardware modules and the flow of software are all described in detail,also include the design parameters.A touch screen and a TFT screen are used in the instrument,so it can display the result vividly,and can be set the parameter easily.In simple test,the nonvital teeth can be distinguished from the healthy teech.To change the fluorescent filter，the instrument can also be used in the detection of dental caries and dental plaque.
