Compositional and structural changes of human dentin following caries removal by Er,Cr:YSGG laser irradiation in primary teeth.
In this in vitro study, the compositional and structural changes of human dentin, and knoop harness of cavity floor following the removal of dental caries by Er,Cr:YSGG laser irradiation in primary teeth was compared with that of the conventional bur cavity. The results confirmed that laser irradiation revealed minimal thermal damage to the surrounding tissues, minimal thermal induced changes of dental hard tissue compositions, and favorable surface characteristic.
