摘要

本研究评估了用于定制纤维桩的不同半透明树脂（Z350 和 Opallis）以及使用不同 LED 设备（V，Valo 或 R，Radi-Cal）光固化粘接系统对 24 小时和 6 个月后粘接强度和粘接失败模式的影响。制备的 80 根牙根分为 4 组（n=20）：ZV（Z350 树脂和 LED Valo）、ZR（Z350 树脂和 LED Radi-Cal）、OV（Opallis 树脂和 LED Valo）、OR（Opallis 树脂和 LED Radi-Cal）。在牙槽骨预备后，定制纤维桩并使用自粘固剂粘接，然后使用 V 或 R LED 设备进行光固化。粘结强度值进行了双向方差分析。在 6 个月的评估中，ZV 和 ZR 组的粘接强度值高于其他组（p

Influence of using different translucent composite resins for customizing fiber post on the bond strength of self-adhesive cement to root dentin.

This study evaluated the influence of different translucent resins (Z350 and Opallis) for customizing fiber posts and light-curing the cementation system using different LED equipment (V, Valo or R, Radii-Cal) on the bond strength and adhesive failure pattern at 24 h and 6 months. Eighty roots were prepared and divided into 4 groups (n=20): ZV (Z350 resin and LED Valo), ZR (Z350 resin and LED Radii-Cal), OV (Opallis resin and LED Valo), OR (Opallis resin and LED Radii-Cal). After post space preparation, the fiber post was customized and cemented with self-adhesive cement and light-curing using V or R LED equipment. Bond strength values were submitted to 2-way ANOVA test. ZV and ZR showed higher bond strength values than the other groups at 6 months of evaluation (p<0.05). The Z350 resin has a favorable influence on the bond strength of self-adhesive cement to root dentin, regardless of the LED polymerization equipment used.

期刊介绍： Dental Materials Journal is a peer review journal published by the Japanese Society for Dental Materials and Devises aiming to introduce the progress of the basic and applied sciences in dental materials and biomaterials. The dental materials-related clinical science and instrumental technologies are also within the scope of this journal. The materials dealt include synthetic polymers, ceramics, metals and tissue-derived biomaterials. Forefront dental materials and biomaterials used in developing filed, such as tissue engineering, bioengineering and artificial intelligence, are positively considered for the review as well. Recent acceptance rate of the submitted manuscript in the journal is around 30%.
