Effect of the CO2 laser on enamel surface roughness after debonding ceramic brackets and the application of nanohydroxyapatite: in-vitro study
Objective Evaluate the effect of the CO2 laser on enamel surface roughness after debonding ceramic brackets and applying nanohydroxyapatite. Methodology Sixty extracted premolars were randomly assigned to four groups (n = 15): G1, G2, G3, G4. Ceramic brackets were bonded to the buccal surface for G1 and G2 groups. Befo...
