Background: porcelain layered zirconia restoration fractures are serious and create an aesthetic and functional dilemma for the patients and the dentist. This demands the development of practical repair options that do not necessitate removing and remaking entire restorations. The roughness of the porcelain surface before repairing material application is considered a critical step.
Objectives: investigated the effect of sandblasting, fractional co2 laser, and hydrofluoric acid as a surface treatment on the roughness of porcelain layered zirconia restorations Method: forty-two zirconia blocks prepared by CAD/CAM technology in dimensions of (10 mm width × 10 mm length×3 mm thickness). Divided into three study groups according to corresponding methods of surface treatment: sandblasting group PS (N=14), fractional CO2 laser group PCO2(N=14), and hydrofluoric acid group PHF (N=14). all the specimens were subjected to surface roughness measurements using a profilometer.
Result: There was a greater surface roughness for the laser group (6.24 um) than for sandblasting surface treatments (2.59 um) and hydrofluoric acid, which shows a similar result with no statistically significant difference from sandblasting (2,14 um).
Conclusion: all surface treatments create roughness on the porcelain surface, and no significant differences were observed between sandblasting and hydrofluoric acid. Better results were observed in the CO2 laser group.
