Abstract
This study aimed to evaluate the bonding performance of self-adhesive flowable resin composites (SARs) to bovine teeth. Three SARs, one experimental, and two commercially available products, were used. The study parameters were shear bond strength (SBS), microleakage, and scanning electron microscopy (SEM) evaluation of bonding interfaces. The SBS of the materials was 14.1-15.1 MPa to enamel, 22.2-23.2 MPa to etched enamel, and 7.4-10.7 MPa to dentin. Specimens with pre-etching showed lower microleakage scores than those without pre-etching. SEM images of the interfaces of the materials showed excellent adaptation regardless of the substrate or etching mode. The study results indicate that enamel pre-etching can improve the bonding performance of SARs.
本研究旨在评估自粘性可流动树脂复合材料(SAR)与牛牙的粘接性能。研究使用了三种 SAR,一种是实验产品,另两种是市售产品。研究参数包括剪切粘接强度(SBS)、微渗漏和粘接界面的扫描电子显微镜(SEM)评估。这些材料对珐琅质的 SBS 为 14.1-15.1 兆帕,对蚀刻珐琅质的 SBS 为 22.2-23.2 兆帕,对牙本质的 SBS 为 7.4-10.7 兆帕。与未预蚀刻的试样相比,预蚀刻试样的微渗漏分数较低。材料界面的扫描电子显微镜图像显示,无论基底或蚀刻模式如何,都能很好地适应。研究结果表明,釉质预蚀刻可以提高 SAR 的粘结性能。
期刊介绍:
Dental Materials Journal is a peer review journal published by the Japanese Society for Dental Materials and Devises aiming to introduce the progress of the basic and applied sciences in dental materials and biomaterials. The dental materials-related clinical science and instrumental technologies are also within the scope of this journal. The materials dealt include synthetic polymers, ceramics, metals and tissue-derived biomaterials. Forefront dental materials and biomaterials used in developing filed, such as tissue engineering, bioengineering and artificial intelligence, are positively considered for the review as well. Recent acceptance rate of the submitted manuscript in the journal is around 30%.
