Abstract

Purpose: The aim of this study was to evaluate the adhesive bond strength of fiberglass posts treated with experimental silanes based on thio-urethane and submitted to thermo and mechanical cycles.

Materials and methods: Bovine roots were divided into six groups: RX-RU2 (RelyX CP + RelyX U200); PETMP-HDDI-RU2 (PETMP-HDDI + RelyX U200); PETMP-BDI-RU2 (PETMP-BDI + RelyX U200); RX-RU (RelyX CP + RelyX Ultimate); PETMP-HDDI-RU (PETMP-HDDI + RelyX Ultimate); PETMP-BDI-RU (PETMP-BDI + RelyX Ultimate). One slice from each root third (n=10) was submitted to the push-out test and the values evaluated with R Program statistical analysis, while the failure pattern assessed in percentage.

Results: Among root thirds, RX-RU2 promoted greater strength at the cervical and apical thirds; PETMP-HDDI-RU2 showed highest values at the three thirds; and PETMP-BDI-RU2 was strongest at the apical third. RX-RU presented higher strength at the apical third, and PETMP-HDDI-RU and PETMP-BDI-RU had similar values at the three thirds. In each root third, PETMP-HDDI-RU2 showed similar strength at all thirds, and similar strength at the apical third was observed for other associations. Mixed and adhesive failures predominated.

Conclusion: Experimental silanes promoted different bond strength values in the adhesion of fiberglass posts to the root thirds, with better results for PETMP-HDDI silane. The root region did not influence the failure pattern and most slices showed mixed (MCDP) or adhesive (ADP) failure.

硫脲基实验硅烷处理玻璃纤维桩的粘接强度。

目的:研究基于硫脲基硅烷的玻璃纤维桩经热、机械循环处理后的粘接强度。材料和方法:牛根分为6组:RX-RU2 (RelyX CP + RelyX U200);PETMP-HDDI- ru2 (PETMP-HDDI + RelyX U200);PETMP-BDI- ru2 (PETMP-BDI + RelyX U200);RX-RU (RelyX CP + RelyX Ultimate);PETMP-HDDI- ru (PETMP-HDDI + RelyX Ultimate);PETMP-BDI- ru (PETMP-BDI + RelyX Ultimate)。每根三分之一(n=10)中的一片提交给推出测试，并使用R Program统计分析评估值，而以百分比评估故障模式。结果:在根三分之一中，RX-RU2在颈椎和根尖三分之一处促进了更大的强度;petmp - hdi - ru2在3 / 3处值最高;PETMP-BDI-RU2在根尖第3位最强。RX-RU在顶端三分之一处强度较高，PETMP-HDDI-RU和PETMP-BDI-RU在顶端三分之一处强度相近。在每个根三分之一中，petmp - hdi - ru2在所有三分之一中表现出相似的强度，在其他关联中也观察到类似的强度。混合和粘接失效占主导地位。结论:实验硅烷对玻璃纤维桩与根三分之一的粘附有不同的促进作用，以PETMP-HDDI硅烷效果较好。根区不影响破坏模式，大多数切片显示混合性(MCDP)或粘连性(ADP)破坏。
