Paper Abstract

The processes of tissue damage up to destruction under laser radiation action which are characterized by definite dynamics of temperature in the region of laser heating are studied using pulsed photothermal radiometry of tissue (PPTR). The thresholds of the water evaporation from tissue and the tissue destruction for different tissues and wavelengths of incident laser radiation are considered. The difference in dentine temperatures when the tissue destruction starts for CO2 and Er lasers is discussed. The features of the destruction processes and the difference of the temperatures corresponding to the tissue destruction thresholds under CO2 laser action for hard and soft tissues are discussed.
