Abstract
Background: For all-ceramic restorations to last a long time, the ceramic veneering and substructure need to have a strong sufficient bond. This research compared how two different surface treatments affected the tensile and shear bond strengths of zirconium-reinforced lithium silicate and porcelain (Suprinity). Materials and Methods: A total of 120 samples were divided into three groups at random: control(no surface treatment),aluminium oxide sandblasting, Erbium, Chromium-doped Yttrium, Scandium, Gallium, and Garnet (Er, Cr: YSGG) laser irradiation, and 60 samples to evaluate tensile bond strength and 60 samples to evaluate shear bond strength. By using one-way ANOVA and the post-hoc Tukey’s test, the tensile and shear bond strength between Suprinity and porcelain (VITA VM 11) was analyzed in all groups. Results: The maximum and minimum tensile bond strength was seen in sandblasting group (7.86 ± 2.22 Mpa) and control group (4.88 ± 1.58 Mpa), respectively (P < 0.001). The amount of shear bond strength in the laser group, sandblast group, and control group was (5.16 ± 1.66 Mpa),(5.00 ± 1.34 Mpa),(4.39 ± 1.54 Mpa) respectively (P = 0.252). In tensile and shear bond strength tests, most failures were cohesive in VITA VM 11 layering porcelain (65.0% vs. 66.7%) followed by mixed failures (33.3% vs. 20%). Conclusion: Suprinity and layering porcelain produced higher tensile bonds as a result of Al2O3 sandblasting and Er, Cr: YSGG laser irradiation. While no pure adhesive failure was seen, cohesive failure was predominant.
期刊介绍:
It is a journal aimed for research, scientific facts and details covering all specialties of dentistry with a good determination for exploring and sharing the knowledge in the medical and dental fraternity. The scope is therefore huge covering almost all streams of dentistry - starting from original studies, systematic reviews, narrative reviews, very unique case reports. Our journal appreciates research articles pertaining with advancement of dentistry. Journal scope is not limited to these subjects and is more wider covering all specialities of dentistry follows: Preventive and Community Dentistry (Dental Public Health) Endodontics Oral and Maxillofacial Pathology Oral and Maxillofacial Radiology Oral and Maxillofacial Surgery (also called Oral Surgery) Orthodontics and Dentofacial Orthopaedics Periodontology (also called Periodontics) Pediatric Dentistry (also called Pedodontics) Prosthodontics (also called Prosthetic Dentistry) Oral Medicine Special Needs Dentistry (also called Special Care Dentistry) Oral Biology Forensic Odontology Geriatric Dentistry or Geriodontics Implantology Laser and Aesthetic Dentistry.
