| Research Abstract |
In this study, focusing on compounds with primary amino groups (highly laser-absorptive substances : HLA), we experimentally produced CDS in which HLA were mixed, and measured their Er:YAG laser absorption rate and efficiency of carious dentin removal, to evaluate the laser absorption properties of CDS mixed with HLA . Erwin AdvErL was used as an Er:YAG laser apparatus (2940nm). 10 pulses of Er:YAG laser irradiation were carried out at 1.0 W ,1 Hz. Regarding the Er:YAG laser, it was considered that safe, efficient, selective caries removal is possible using caries-detecting dye solutions mixed with highly laser-absorptive substances.
