Abstract

OBJECTIVES

The purpose of this study was to investigate the influence of saliva contamination and cleaning methods on adhesive bonding to dental zirconia ceramic with a phosphate-monomer-containing luting resin.

METHODS

After saliva immersion, airborne-particle abraded ceramic specimens were cleaned with water rinsing, with isopropanol, with phosphoric acid gel, or with additional airborne-particle abrasion. Airborne-particle abraded specimens without contamination were used as the control group. Chemical analysis of the ceramic surfaces of all groups was done using X-ray photoelectron spectroscopy (XPS). The influence of contamination and cleaning methods on ceramic bond durability was examined by tensile bond strength (TBS) testing after 3 days or 150 days water storage with 37,500 thermal cycles.

RESULTS

After saliva contamination XPS revealed an organic coating which was not removed completely with water rinsing, with isopropanol, or with phosphoric acid. Using TBS testing a strong influence of contamination and cleaning methods on resin bond strength and its durability was found.

SIGNIFICANCE

Saliva contamination significantly affected resin bonds to zirconia ceramic and its durability. Airborne-particle abrasion was the most effective cleaning method.

摘要

目的

本研究旨在探讨唾液污染和清洁方法对使用含磷酸盐单体的粘接树脂与牙科氧化锆陶瓷粘接的影响。

方法

唾液浸泡后，对经空气颗粒研磨的陶瓷试件分别采用水冲洗、异丙醇、磷酸凝胶或再次进行空气颗粒研磨进行清洁。未受污染的经空气颗粒研磨的试件作为对照组。使用X射线光电子能谱（XPS）对所有组的陶瓷表面进行化学分析。通过在37500次热循环及储存3天或150天后进行拉伸粘接强度（TBS）测试，研究污染和清洁方法对陶瓷粘接耐久性的影响。
