Paper Abstract

The present work represents the results of research of mechanical strength formed by submillisecond pulses of Er-laser at the border of enamel-seal and dentine-seal in a cavity. Comparative research of an adhesion of three of the most widespread types of modern seal materials (cement, amalgam, polymer) to walls of the laser cavity are conducted. The comparison of `laser adhesion' with adhesion of these materials to the walls of the cavity has been made by the usual mechanical tools. The dependence of free adhesion energy from the geometry of the cavity and energy density of laser radiation is considered. This work informs the reader about the results of research removal efficiency of some modern seal materials. The influence of water-spray on the efficiency of seal materials laser treatment process is considered.
