Abstract

Background

To assess the shear bond strength (SBS) of four calcium silicate-based cements (CSCs) to composite resin using a universal adhesive in self-etch (SE) and etch-and-rinse (ER) modes and to evaluate surface microstructure and chemical composition of CSCs after acid-etching.

Methods

In total, 30 specimens of each cement, Biodentine (BD), mineral trioxide aggregate (MTA) Angelus (MTA-A), ProRoot MTA (MTA-P) and MTA Repair HP (MTA-HP), were prepared and assigned into 2 groups (n = 15) according to universal adhesive (Clearfil Universal Bond Quick) applied in SE and ER mode. After composite resin (Clearfil Majesty Esthetic) was applied, the SBS was measured. Scanning electron microscope-energy dispersive spectroscopy (SEM–EDS) analysis was used to evaluate the changes in surface structure and elemental composition.

Results

MTA-P demonstrated significantly higher SBS than all CSCs, except for MTA-HP in the SE mode. The ER mode exhibited significantly higher SBS compared to the SE mode for MTA-P and MTA-A. Acid-etching caused morphological differences and affected elemental distribution.

Conclusions

MTA-P may be a more suitable pulp capping material due to its superior SBS compared to BD and MTA-A. The application of a universal adhesive in ER mode may be suggested to increase the SBS of MTA-P and MTA-A to composite resin.

硅酸钙基水泥与复合树脂在不同应用模式下的剪切结合强度:体外研究。

背景：评估四种硅酸钙基水泥（CSCs）在自蚀刻（SE）和蚀刻-漂洗（ER）模式下与复合树脂的剪切结合强度（SBS），并评估酸蚀后CSCs的表面微观结构和化学成分，制备ProRoot MTA（MTA-P）和MTA修复HP（MTA-HP）并将其分为2组（n = 15）根据在SE和ER模式中应用的通用粘合剂（Clearfil universal Bond Quick）。在应用复合树脂（Clearfil Majesty Esthetic）之后，测量SBS。扫描电子显微镜能量色散光谱（SEM-EDS）分析用于评估表面结构和元素组成的变化。结果：除SE模式下的MTA-HP外，MTA-P的SBS明显高于所有CSC。与MTA-P和MTA-A的SE模式相比，ER模式表现出显著更高的SBS。酸蚀引起形态差异，影响元素分布。结论：与BD和MTA-a相比，MTA-P具有更好的SBS，可能是一种更合适的盖髓材料。可以建议在ER模式下应用通用粘合剂来增加MTA-P和MTA-a对复合树脂的SBS。
