抄録

In the present study, we demonstrated the effects of carbon dioxide (CO2) laser irradiation on the physical process of repairing the enamel surface structure after power bleaching. Under a scanning electron microscope, the structure of the enamel surface was subjected to bleaching treatment using CO2 laser in combination with 30% H202 and showed preferen tial removal of rods. Fluoridation using CO2 laser irradiation (24.9 J/cm2) changed the damaged enamel surface to an even flat structure. Furthermore, the adhesion of hydroxyapatite (HA) particles could be seen on the enamel surface after application of HA and CO2 irradiation (218.4 J/cm2); the HA particles had remained on the enamel surface despite ultrasound washing. These findings indicate that HA particle coating on the enamel surface can be achieved by CO2 laser irradiation, suggesting that this method way be used for repairing the damaged enamel surface after power bleaching.
