Abstract

Objectives

This study evaluated the effect of universal adhesives (UAs) applied as Immediate Dentin Sealing (IDS) on the shear bond strength (SBS) of dual-cure resin cement, both immediately and after thermocycling aging.

Material and Methods

A total of 180 bovine incisors were prepared and randomly assigned to six groups (n = 15): NOC (control), Clearfil Universal Bond Quick (CUBQ), G-Premio Bond (GPB), Peak Universal Bond (PUB), Adhese Universal (AU), and Scotchbond Universal Plus (SBUP). Specimens were cemented with dual-cure resin cement (Panavia V5) and subjected to SBS testing at 24 h and after thermocycling (10,000 cycles, 5°C–55°C). SBS was measured using a universal testing machine, and failure modes were assessed microscopically. Statistical analysis was conducted using a Generalized Linear Model with Bonferroni correction (p < 0.05).

Results

Significant differences were found among UAs (p < 0.001) and after aging (p < 0.001). SBUP and GPB had the highest SBS before and after thermocycling, while NOC had the lowest. Thermocycling reduced SBS in all groups, with CUBQ and AU showing the largest declines. Failure mode analysis showed predominantly adhesive failures in NOC, while IDS groups had more cohesive and mixed failures.

Conclusion

IDS technique with universal adhesives significantly enhances bond strength to dentin compared to conventional cementation. SBUP and GPB showed superior bonding performance, likely due to their monomer formulations containing 10-MDP and acetone, which are known to improve chemical adhesion to dentin and promote effective resin infiltration. Thermocycling led to a reduction in SBS across all groups, highlighting the impact of aging on adhesive durability, underscoring the importance of selecting UAs with lasting adhesive strength for long-term bonding.

各种通用胶粘剂即刻牙本质密封对双固化树脂水泥抗剪强度的影响

目的研究通用胶粘剂（UAs）作为即刻牙本质密封剂（IDS）对双固化树脂水泥即刻和热循环老化后剪切强度（SBS）的影响。材料与方法制备180只牛切牙，随机分为6组（n = 15）： NOC组（对照组）、Clearfil Universal Bond Quick组（CUBQ组）、G-Premio Bond组（GPB组）、Peak Universal Bond组（PUB组）、Adhese Universal Bond组（AU组）和Scotchbond Universal Plus组（SBUP组）。采用双固化树脂水泥（Panavia V5）对试件进行胶结，并在24 h和热循环（5°C - 55°C, 10,000次循环）后进行SBS测试。使用通用试验机测量SBS，并在显微镜下评估失效模式。采用Bonferroni校正的广义线性模型进行统计分析（p < 0.05）。结果UAs组（p < 0.001）与老年组（p < 0.001）差异有统计学意义。SBUP和GPB在热循环前后的SBS最高，NOC最低。热循环降低了所有组的SBS，其中CUBQ和AU的下降幅度最大。失效模式分析显示，NOC组以粘结失效为主，而IDS组则以粘结和混合失效为主。结论与常规固接相比，采用通用粘接剂的IDS技术可显著提高与牙本质的结合强度。SBUP和GPB表现出优异的粘合性能，这可能是由于它们的单体配方中含有10-MDP和丙酮，已知它们可以改善与牙本质的化学粘附并促进有效的树脂渗透。热循环导致所有组中SBS的减少，突出了老化对粘合剂耐久性的影响，强调了选择具有持久粘合强度的ua的重要性。

期刊介绍： Clinical and Experimental Dental Research aims to provide open access peer-reviewed publications of high scientific quality representing original clinical, diagnostic or experimental work within all disciplines and fields of oral medicine and dentistry. The scope of Clinical and Experimental Dental Research comprises original research material on the anatomy, physiology and pathology of oro-facial, oro-pharyngeal and maxillofacial tissues, and functions and dysfunctions within the stomatognathic system, and the epidemiology, aetiology, prevention, diagnosis, prognosis and therapy of diseases and conditions that have an effect on the homeostasis of the mouth, jaws, and closely associated structures, as well as the healing and regeneration and the clinical aspects of replacement of hard and soft tissues with biomaterials, and the rehabilitation of stomatognathic functions. Studies that bring new knowledge on how to advance health on the individual or public health levels, including interactions between oral and general health and ill-health are welcome.
