Effect of high-power Nd:YAG laser on the growth of and : an experimental study.

[Purpose] The aim of this study was to evaluate the effect of high-power Nd:YAG laser on and bacterial growth. [Materials and Methods] Seven samples of and seven samples of were prepared in the microbiology lab, one used as a control sample and the remaining six samples used as experimental samples, which were irradiated by a high-power laser (LASERSIX ME, 15W) with a total dose of 500 and 700 J. The primary measure was the semi-qualitative assessment of turbidity and bacterial count; the turbidity was assessed 24 h after laser application.
