Abstract

The thermal behavior of collagen in intact and IR laser irradiated nucleus pulpose tissues was studied. The enthalpy of denaturation of the intact tissue was determined (53.1 ± 1.2 J/g of collagen). The denaturation of collagen during laser heating at temperatures below the characteristic melting point occurred under the influence of the photomechanical component of laser irradiation.
