Abstract

The purpose of this study was to apply the photoplethsmography(PPG) as a non-invasive tool to evaluate the blood flow of the anterior tooth in clinic. The system consist of two light-emitting diodes(LED) powered by 5V as the light source. The LED was designed to two weve lengths, 940(infrared) and 660(red)nm simultaneously with a 36nm bandwidth at half the peak intensity. The 54 anterior vital tooth were examined and the measured was analysed in frequency domian (power spectrum).(omitted)
