虽然相对较高的CO2激光能量已被证明可以消毒根管，但几种细菌菌株对CO2激光能量暴露减少的反应仍然未知。将新鲜生长的细菌细胞照射在玻璃显微镜盖玻片上。对不同参数的等效能量暴露进行了细菌活力的比较。在杀死密切相关的细菌物种所需的能量方面没有发现统计学上的显著差异。然而，杀死大于99.5%的细菌所需的能量密度小于200 J/cm 2，远低于先前研究中显示的灭菌能量密度。
Although relatively high CO2 laser energies have been shown to sterilize root canals, the response of several bacterial strains to decreasing exposures of CO2 laser energy remains unknown. Freshly grown bacterial cells were irradiated on glass microscope coverslips. A comparison of equivalent energy exposures with differing parameters was made on the bacterial viability. No statistically significant difference was found in the energy required to kill closely related bacterial species. However, the energy density required to kill greater than 99.5% of the bacteria is less than 200 J/cm2, much less than that shown to sterilize in a previous study.
