Abstract
This study aimed to evaluate the initial bond strength to dentin with a new self-adhesive resin composite containing a hydrophilic amide monomer using a micro tensile bond strength (μTBS) test. Specimens were ground with #600 SiC. Including a Cleafil Universal Bond Quick ER (UBQ) and resin composite, a new self-adhesive resin composite (SA-100R; SAR), and a commercially self-adhesive resin composite (Constic; CON), were tested. Adhesion procedures were conducted according to each manufacturer's instructions. Specimens were stored for 24 h in water at 37ºC, then cut into a 1.0×1.0 mm beams. μTBS tests were conducted at a cross-head speed of 1.0 mm/min. Data were statistically analyzed using one-way ANOVA and Bonferroni correction. SAR exhibited values significantly higher than CON (p<0.05), probably due to the improved dentin diffusion by the amide monomer. SAR exhibited stronger adhesion than the CON, shows a high potential for use in various clinical applications, e.g., home-visit dental care.
采用微拉伸结合强度（μTBS）测试方法，评价含亲水性酰胺单体的新型自粘树脂复合材料与牙本质的初始结合强度。样品用#600 SiC研磨。包括Cleafil Universal Bond Quick ER （UBQ）和树脂复合材料，一种新型自粘树脂复合材料(SA-100R；SAR)和商用自粘树脂复合材料(Constic；CON)，被测试过。根据每个制造商的说明进行粘合程序。标本在37℃的水中保存24 h，然后切成1.0×1.0 mm的梁。μTBS实验以十字速度1.0 mm/min进行。数据采用单因素方差分析和Bonferroni校正进行统计学分析。SAR值显著高于CON值(p
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%.
