IMAGES OF THE MORPHOLOGY CHANGE OF 30 HYDROGEN PEROXIDE APPLIED TOHUMAN ENAMEL BY MEANS OF OPTICAL COHERENCE TOMOGRAPHY

摘要

There is still some controversy in the tooth whitening whether hydrogen peroxide bleaching causes the microstructure changes of human enamel. One of the reasons for this controversy is that there is as yet no reliable, non-destructive in vitro method for imaging and assessing the morphology changes in bleached teeth. So we have used an OCT system for investigations of enamel. We have imaged before and after 30% hydrogen peroxide bleaching enamel and demonstrated the detection of the changes in tooth tissue microstructure. We discuss the details of images and its potential and limitations with respect to dental applications.
