Abstract

Controlling the optical properties of biological tissues is one of the most important current tasks of clinical medicine not only for detecting the initial forms of diseases but also for effective phototherapy and laser surgery. In the course of in vitro studies of dentin specimens, using reflection spectroscopy, the effective diffusion coefficient of a 40% aqueous solution of glucose in dentin was computed and was found to be (5.4±0.8)×10−6cm2/s. The optical clearing efficiency of human dentin immersed in a 40% solution of glucose was determined by measuring the total transmission of the samples in the spectral range from 200 to 800 nm. It was found that the clearing efficiency is greatest at 250 nm after 90 min of action by a 40% solution of glucose and equals 370%, while that at 400 nm is 83%.
