Abstract

OBJECTIVE

The objective of this study was to compare the light transmittance of fiber posts following application of various surface treatments.

MATERIALS AND METHODS

Fiber post specimens (Snowpost red size #14) were tested (n = 7). The fiber posts were divided into five groups according to the application of surface treatments: Group 1: No surface treatment; Group 2: Etched with hydrofluoric acid (HF) + silane application; Group 3: Airborne-particle abraded with 110 μm Al2O3; Group 4: Irradiated with erbium: Yttrium-aluminum-garnet laser; Group 5: Airborne-particle abraded with 110 μm Al2O3 + silane application. The light transmittance of the specimens was compared using a spectrophotometer. Statistical significance was determined using one-way analysis of variance (ANOVA) (α = 0.05).

RESULTS

One-way ANOVA revealed that surface treatment had significant effects on light transmittance of posts (P < 0.001). While laser treatment had the highest percentage of light transmittance, treatment with silane following HF application had the lowest.

CONCLUSION

Application of surface treatments might negatively affect the light transmission property of fiber posts.

摘要

目的

本研究的目的是比较应用各种表面处理后纤维桩的透光率。

材料与方法

对纤维桩样本（Snowpost红色14号）进行测试（n = 7）。根据表面处理的应用将纤维桩分为五组：第1组：未进行表面处理；第2组：用氢氟酸（HF）蚀刻+应用硅烷；第3组：用110μm氧化铝进行空气颗粒研磨；第4组：用铒：钇铝石榴石激光照射；第5组：用110μm氧化铝进行空气颗粒研磨+应用硅烷。使用分光光度计比较样本的透光率。使用单因素方差分析（ANOVA）确定统计学意义（α = 0.05）。
