The Treatment of Tooth Root Canaliculi with Laser withX-ray Contrast Waveguide
Ošetření zubních kanálů za použití laserus RTG kontrastním vlnovodem
Cílem studie bylo zhodnotit RTG kontrastní vlnovod a jeho aplikace v endodoncii. V pokusubyly použity dva laserové systémy (Er:YAG a Alaxandrit s vlnovými délkami 2940 nm a 375nm). Bylo endodonticky ošetřeno 10 extrahovaných zubů. V kanálku byla sledována RTGkontrastnost kovového nástroje a vlnovodu. Po aplikaci dávky laserového záření byly zubyrozříznuty v podélné ose a povrch kanálku byl kontrolován v elektronovém rastrovacím mikroskopu.Rozdíly v RTG kontrastnosti vlnovodu a kovového nástroje nebyly zjištěny. Rozdílyv RTG kontrastnosti vlnovodu a kovového nástroje nebyly zjištěny. Po aplikaci laserovéhozáření byla nalezena hladká vyčištěná stěna bez přítomnosti „smear layer“ se zatavenýmidentinovými tubuly.

Overview
The aim of study was to check the application of a new x-ray contrast hollowwaveguide 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 wereused. The root canals of 10 teeth were treated endodontically and result of that treatment wascompared with the common cleaning methods. During the treatment the x-ray images weretaken with conventional files and using this new design hollow waveguide. After laser therapythe teeth were cut in a longitudinal axis and viewed using the scanning electron microscope. Itwas demonstrated that no differences exist between of x-ray opacity of the metal instrumentused for the endodontic treatment and the special hollow waveguide. In SEM the open dentinaltubules were visible. No cracks were determined. A smear layer was removed. The surfacemodification after laser treatment was not found.
