Abstract

Objective This in vitro study was aimed to determine the effect of composite polymerization methods with universal adhesive on push-out bond strength in coronal dentin. Materials and Methods Using 48 healthy premolar teeth, the almost conical access cavities were excised to the canal entry. Cavity preparations were treated with a universal adhesive in the self-etch mode. Teeth were randomly divided into four groups (n = 12). It was used to restore the cavities with a bulk-fill composite; Tetric N-Ceram, a conventional composite; Filtek Z250, a dual-cure composite; Rebilda DC VOCO, and chemical cure composite; Master-Dent. After applying 10,000 thermal cycles, 1-mm incisions were made in coronal dentin, and slices were placed in a UTM machine in a special jig and tested for push-out bond strength at a crosshead speed of 0.5 mm/min. Data were analyzed using one-way analysis of variance and Games–Howell tests (p < 0.05). Results The highest mean bond strength was of the conventional composite (18.36 ± 5.63) and the lowest mean of bond strength was for the dual-cure composite (5.10 ± 2.74). There was a significant difference among the means of bond strength for various composite resins curing (p < 0.001). Conclusion The bulk-fill and conventional light-cured composites had higher bond strength than self- and dual-cured composite resins.

通用胶粘剂复合聚合方法对牙冠的挤出结合强度

客观的本体外研究旨在确定具有通用粘合剂的复合聚合方法对冠状牙本质推出粘结强度的影响。材料和方法使用48颗健康的前臼齿，切除了几乎是圆锥形的进入腔，直到进入管。空腔制剂在自蚀刻模式下用通用粘合剂进行处理。将牙齿随机分为四组（n = 12）。它被用来用大块填充复合材料修复空腔；Tetric N-Ceram，一种传统的复合材料；Filtek Z250，一种双固化复合材料；再生直流VOCO，化学固化复合材料；Master Dent。在施加10000个热循环后，在牙冠牙本质上形成1mm的切口，并将切片放置在特殊夹具中的UTM机器中，并在0.5的十字头速度下测试推出粘合强度 mm/分钟。采用单向方差分析和Games–Howell检验对数据进行分析（p < 0.05）。结果平均粘结强度最高的是传统复合材料（18.36 ± 5.63），并且粘合强度的最低平均值为双固化复合材料（5.10 ± 2.74）。各种复合树脂固化的粘结强度平均值之间存在显著差异（p < 0.001）。结论本体填料和常规光固化复合材料比自固化和双固化复合树脂具有更高的粘结强度。

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.
