Effect of CO2 laser irradiation on shear bond strength and enamel surface roughness after ceramic brackets removal: in vitro study
This study aimed to evaluate the shear bond strength and surface roughness of the enamel after removal of ceramic brackets with CO2 laser. Thirty extracted premolars were randomly assigned to three groups (n = 10): Untreated enamel (GI), Conventional debonding (GII), and CO2 laser debonding (GIII). Polycrystalline cera...
