Summary: The aim of study was to check the application of a new x-ray contrast hollow
waveguide which is suitable for x-ray diagnostics and treatment required in endodontics.
Er:YAG and Alexandrie laser system generating a wavelength of 2940 nm and 375 nm were
used. The root canals of 10 teeth were treated endodontically and result of that treatment was
compared with the common cleaning methods. During the treatment the x-ray images were
taken with conventional files and using this new design hollow waveguide. After laser therapy
the teeth were cut in a longitudinal axis and viewed using the scanning electron microscope. It
was demonstrated that no differences exist between of x-ray opacity of the metal instrument
used for the endodontic treatment and the special hollow waveguide. In SEM the open dentinal
tubules were visible. No cracks were determined. A smear layer was removed. The surface
modification after laser treatment was not found.
