Abstract

The aim of this study was to determine the effects of varying parameters of Er:YAG laser irradiation with and without water spray cooling on root canal dentin in vitro. After horizontally removing tooth crowns from extracted human teeth, roots were axially sectioned into thin slices, exposing the root canal surface. An Er:YAG laser delivered 10-30 J/cm² into a 0.4-mm diameter laser spot on the root canal surface .Single pulses of different lengths were applied with and without water spray cooling/irrigation, and sequences of 3 pulses at a repetition rate of 30 Hz were applied at selected pulse parameters. The irradiated samples were investigated using confocal laser scanning microscopy (CLSM). At most irradiation conditions, root canal dentin surface was ablated. 3D images from CLSM revealed that the cavity walls were not smooth. Depths, diameters and micro surfaces of the cavities revealed a significant different between the cavities.
