Impacto de los sistemas de irrigación láser en la desinfección del conducto radicular: un estudio in vitro...

The disinfection outcome between laser-activated irrigation procedures as well as standard irrigation methods in root canals is of interest. Endodontic debris removal was most effective when Er:YAG laser-activated irrigation used PIPS and SWEEPS modalities because they achieved higher bacterial reduction rates and debris elimination rates than Nd:YAG laser and conventional irrigation and ultrasonic techniques. The PIPS method performed equally well or slightly better than SWEEPS in removing calcium hydroxide from the canal space. Thus, we show that Er:YAG laser-activated irrigation provides extensive benefits for endodontic success by effectively sterilizing the canal space and cleaning it efficiently.
