Investigation of bacterial activity in products of destruction of enamel and dentine

摘要

Abstract: The results of the investigation of bacteria (streptococcus, staphylococcus, bacillus subtillis) vitality in products of a destruction of human hard dental tissues simulated by submillisecond YAG:Er and YSGG:Cr;Er laser pulses are first represented at this lecture. The dependencies of bacteria vitality from energy density and Er-laser radiation exposure are given also. The problems of availability of some possible mechanisms of bacteria destruction by Er-laser submillisecond pulses are talked over.!4
