Effect of Different Surface Treatments on the Surface Roughness and Orthodontic Bond Strength of Partially-stabilized Zirconia.https://doi.org/10.4274/meandros.galenos.2022.23600https://hdl.handle.net/20.500.12713/3336Objective: To investigate the effect of different surface treatments on the surface roughness (Ra) and shear bond strength (SBS) of partially stabilized zirconia (Y-PSZ) with different yttrium content.Materials and Methods: Zirconia samples were milled from 5Y-PSZ and 4Y-PSZ disks and divided into 5 groups: Control (C), sandblasting (APA), single-step self -etch primer etching (MEP), Er:YAG laser (ER), and femtosecond laser (FS) irradiation (n=11). Surface Ra was measured and metallic mandibular incisor brackets were bonded. SBS test was performed after thermocycling. Data were analyzed using two-way ANOVA and Tamhane's T2 tests (alpha=0.05).Results: Only surface treatment affected Ra and SBS (p<0.001). FS groups had the highest (p<0.001), and C groups had the lowest values Ra (p <= 0.001). MEP groups had lower Ra than ER and APA (p <= 0.002). FS and APA groups resulted in the highest SBS (p<0.001), while MEP groups achieved significantly higher SBS than ER groups (p<0.001). The C group showed the lowest SBS (p<0.001).Conclusion: Within the limitations of this in vitro study, sandblasting and FS irradiation was found to be the most effective surface treatments for metallic bracket bonding to Y-PSZ.eninfo:eu-repo/semantics/openAccessArıPrimeFemtosecond LaserMonobond EtchPartially Stabilized ZirconiaArticle233335342WOS:000863981400012ESCI10.4274/meandros.galenos.2022.236001135267
