Abstract

The purpose of the present study was to compare the influence of post-surface treatment with silane, hydrogen peroxide, hydrofluoric acid or sandblasting and to investigate the effect of silane in combination of the other treatments on the microtensile bond strength between fiber posts and composite resins for core build-up. Thirty-two glass-fiber posts (FRC Postec Plus, Ivoclar Vivadent, Schaan, Liechtenstein) were divided into eight groups according to the different surface pretreatments performed: silane application (S); immersion in 28% hydrogen peroxide (HP); immersion in hydrogen peroxide followed by application of silane (HP-S); immersion in 4% hydrofluoric acid gel (HF); immersion in hydrofluoric acid gel followed by application of silane (HF-S); sandblasting with aluminum oxide particles (SB); sandblasting followed by application of silane (SB-S). In control group, no surface treatment was performed. The composite resin (Tetric Flow, Ivoclar Vivadent, Schaan, Liechtenstein) was applied onto the posts to produce the composite cylinder specimen. It was sectioned into sticks to measure the microtensile bond strength. The data was analyzed with one-way ANOVA and LSD test for post hoc comparison (p < 0.05). Post pretreatment with sandblasting enhanced the interfacial strength between the fiber posts and core materials. Moreover, sandblasting followed by application of silane appears to be the most effective method that can improve the clinical performance of glass fiber posts.

본 연구의 목적은 실란, 과산화수소, 불산, 샌드블라스팅을 이용한 섬유포스트의 표면 처리가 복합레진 코어와의 결합강도에 미치는 영향을 평가하기 위한 것이다. 32개의 FRC Postec Plus를 표면 처리를 하지 않은 대조군과 표면 처리 방법에 따라 7개의 실험군(S군, HP군, HP-S군, HF군, HF-S군, SB군, SB-S군)으로 분류하였다. S군은 실란을 적용하였고, HP군은 28%의 과산화수소로 부식하였으며, HP-S군은 과산화수소 처리 후 실란을 적용하였다. HF군은 4% 불화수소산 젤로 부식하였고, HF-S군은 불화수소산 젤 처리 후 실란으로 처리하였다. SB군은 산화 알루미늄으로 샌드블라스팅 하였고, SB-S군은 샌드블라스팅 후 실란을 적용하였다. 표면 처리한 포스트는 Tetric Flow를 사용하여 광중합 시키면서 주위에 원통형의 코어를 축조하였다. 형성된 포스트-코어 복합체를 막대 형태로 절단하여 미세인장결합강도를 측정하였다. One-way ANOVA와 LSD test로 결합강도 값을 분석한 결과, 샌드블라스팅은 섬유포스트와 복합레진 코어와의 결합력을 증가시켰으며 샌드블라스팅 후 실란으로 처리한 경우 다른 처리 방법들보다 유의하게 증가된 결합력을 나타냈다(p < 0.05).
