    Efficiency of pulsed Er,Cr:YSGG laser induced photoacoustic streaming as a cavity disinfectant against streptococcus mutans
    Author(s): Rand Kareem Jassim* and Hussein Ali Jawad

    Aim: the goal of this study was to determine the antibacterial effectiveness of photon induced photo acoustic streaming using Er, Cr:YSGG laser at short pulse duration against heavily colonized teeth with streptococcus mutans in vitro. Material and Methods: in this study we used twenty eight extracted third molars free of caries, cracks, restoration and other defects. In order to conduct the tooth cavity model test, cylindrical cavities were prepared in the flat occlusal dentin of the teeth. The teeth were stored at 37°C for 72 hours in a broth culture of Streptococcus mutans allowing bacterial invasion. The teeth were then distributed into four groups of seven teeth (14 cavity preparations). The cavities in the first group were left untreated as a control. In the second group the chlorhexidine gluconate–based cavity disinfectant were applied according to the manufacturer&rs.. Read More»
