摘要

背景:本研究的目的是评估三种不同的硅酸钙基水泥(CBCs)与两种不同的大块填充复合树脂(CRs)的剪切结合强度。方法:制备直径为4mm，厚度为2mm的有机玻璃模具(n = 60)。将Biodentine、NeoPutty和MTA Cem LC样品随机分为两个亚组，每组10个样品。样品表面风干，应用Single Bond万能胶。高度为4毫米、内径为2毫米的圆柱形塑料胶囊(属于Filtek Bulk-fill和EverX Posterior cr)集中在涂层材料上聚合20秒。在剪切粘结强度(SBS)测试后，所有样品都通过扫描电子显微镜(SEM)检查以确定破坏模式。制备了3个样品，每组1个，以评估CBCs的化学成分，并用能量色散x射线光谱进行表面元素分析。结论:根据本研究的发现，MTA Cem LC在两个cr中具有最高的SBS值。©2023澳大利亚牙科协会。

Analysis of the bond strength between conventional, putty or resin-modified calcium silicate cement and bulk fill composites

Background

The aim of this study was to evaluate the shear bond strength of three different calcium silicate-based cements (CBCs) with two different bulk-fill composite resins (CRs).

Methods

Plexiglas moulds with a diameter of 4 mm and a thickness of 2 mm were prepared (n = 60). The Biodentine, NeoPutty and MTA Cem LC samples were randomly divided into two subgroups containing 10 samples each. Surfaces of samples were air dried and Single Bond universal adhesive was applied. Cylindrical plastic capsules of 4 mm height and 2 mm inner diameter belonging to Filtek Bulk-fill and EverX Posterior CRs were centred on coating material and polymerized for 20 s. After shear bond strength (SBS) testing, all samples were examined by scanning electron microscopy (SEM) to identify failure patterns. Three samples, one from each group, were prepared to evaluate chemical composition of CBCs and examined with an energy dispersive X-ray spectroscopy for surface elemental analysis.

Results

The values obtained from the tests were evaluated as statistically significant (P < 0.05). After SBS testing, the difference between all CBCs was statistically significant in both CRs.
