Abstract

Abstract Objective Bonding to different dentin substrates influences resin composite restoration outcomes. This study investigated the influence of different adhesion protocols on the shear bond strength of universal adhesive systems to sound and artificial caries-affected dentin (CAD). Materials and Methods Occlusal enamel of 80 premolars were wet grinded to obtain flat midcoronal dentin. Specimens were equally divided according to the substrate condition: sound and CAD by subjecting to pH-cycling for 14 days. Each dentin substrate was bonded with the adhesive systems used in this study: Single Bond universal adhesive or Prime&Bond universal (applied either in etch-and-rinse or self-etch adhesion protocol). Adhesive systems were utilized according to manufacturers’ instructions, then resin composite was built up. Specimens were tested for shear bond strength. The data were analyzed by three-way analysis of variance, and failure modes were determined using stereomicroscope. Results There was no statistically significant difference between the two tested adhesive systems on artificially created CAD with different adhesion protocols. On sound dentin, Single Bond universal, either in the etch-and-rinse or self-etch adhesion protocols, revealed higher statistically significant shear bond strength mean values compared with CAD. Conclusion Single Bond universal adhesive in an etch-and-rinse adhesion protocol improved only bonding to sound dentin, while no added positive effect for the etching step with Prime&Bond universal adhesive was found when bonded to both sound and CAD substrates. The influence of CAD on the performance of the universal adhesives was material-dependent.

不同黏附方式对通用黏附系统与天然及人工牙本质剪切黏附强度的影响

抽象目标与不同牙本质基质的结合会影响树脂复合材料的修复效果。本研究探讨了不同的粘接方案对通用粘接系统与受健全和人工龋齿影响的牙本质（CAD）的剪切结合强度的影响。材料和方法对80颗前磨牙的咬合釉质进行湿磨，获得平坦的中冠牙本质。通过对样品进行14天的pH循环，根据基质条件（声音和CAD）对样品进行等分。每个牙本质基质都用本研究中使用的粘合剂系统粘合：Single Bond通用粘合剂或Prime&Bond通用（用于蚀刻和漂洗或自蚀刻粘合协议）。根据制造商的说明使用粘合剂系统，然后构建树脂复合材料。对试样进行剪切结合强度测试。通过三元方差分析对数据进行分析，并使用立体显微镜确定故障模式。后果在具有不同粘附方案的人工创建CAD上，两种测试的粘附系统之间没有统计学上的显著差异。在完好的牙本质上，Single Bond universal，无论是在蚀刻和冲洗还是自蚀刻粘附方案中，与CAD相比，都显示出更高的统计显著剪切粘合强度平均值。结论蚀刻和冲洗粘合方案中的Single Bond通用粘合剂仅改善了与完好牙本质的粘合，而当与完好和CAD基底粘合时，没有发现Prime&Bond通用粘结剂对蚀刻步骤的额外积极作用。CAD对通用胶粘剂性能的影响与材料有关。

期刊介绍： European Journal of General Dentistry (EJGD) is one of the leading open-access international dental journal within the field of Dentistry. The aim of EJGD is publishing novel and high-quality research papers, as well as to influence the practice of dentistry at clinician, research, industry and policy-maker level on an international basis. EJGD publishes articles on all disciplines of dentistry including the cariology, orthodontics, oral surgery, preventive dentistry, periodontology, endodontology, operative dentistry, fixed and removable prosthodontics, dental biomaterials science, long-term clinical trials including epidemiology and oral health, technology transfer of new scientific instrumentation or procedures, as well as clinically relevant oral biology and translational research.Moreover, EJGD also publish the scientific researches evaluating the use of new biomaterials, new drugs and new methods for treatment of patients with different kinds of oral and maxillofacial diseases or defects, the diagnosis of oral and maxillofacial diseases with new methods, etc. Moreover, researches on the quality of life, psychological interventions, improving disease treatment outcomes, the prevention, diagnosis and management of cancer therapeutic complications, rehabilitation, palliative and end of life care, and support teamwork for cancer care and oral health care for old patients are also welcome. EJGD publishes research articles, case reports, reviews and comparison studies evaluating materials and methods in the all fields of related to dentistry.
