Abstract

This study evaluated the effect of resin cements and post-space irrigation solutions on the push-out bond strength of diabetic and non-diabetic dentin. A total of 160 human central teeth (80 diabetic, 80 non-diabetic) were prepared using X5 files and obturated with AH Plus sealer and X5 gutta-percha. Post spaces were prepared, and teeth were divided into eight groups based on resin cements (Variolink N, Panavia SA Universal) and irrigation protocols (saline, saline + 2% CHX). A 1 mm slice from each tooth's middle third was tested for push-out bond strength. Statistical analysis was performed using three-way ANOVA and Tukey HSD tests. In non-diabetic dentin, saline + CHX with Variolink N achieved the highest bond strength. In diabetic dentin, saline with Panavia SA Universal resulted in the lowest bond strength (p < 0.05). The dentin type, resin cement, and irrigation solution significantly impacted fiber post bond strength, and CHX irrigation improved it.

提高糖尿病牙本质纤维桩的推出结合强度：氯胺冲洗和树脂胶结剂的作用。

本研究评估了树脂胶结剂和间隙灌洗液对糖尿病和非糖尿病牙本质推出结合强度的影响。采用X5锉制备人中牙160颗（糖尿病80颗，非糖尿病80颗），并用AH Plus封口剂和X5胶封闭。准备好桩位，根据树脂胶结剂（Variolink N, Panavia SA Universal）和冲洗方案（生理盐水，生理盐水+ 2% CHX）将牙齿分为8组。从每颗牙齿中间的三分之一处取1毫米的切片，测试推出的粘结强度。统计学分析采用三向方差分析和Tukey HSD检验。在非糖尿病牙本质中，盐水+ CHX与Variolink N的结合强度最高。在糖尿病牙本质中，Panavia SA Universal盐水的结合强度最低（p < 0.05）。牙本质类型、树脂水泥和灌洗液对纤维桩粘结强度有显著影响，CHX灌洗能改善纤维桩粘结强度。

期刊介绍： Journal of Functional Biomaterials (JFB, ISSN 2079-4983) is an international and interdisciplinary scientific journal that publishes regular research papers (articles), reviews and short communications about applications of materials for biomedical use. JFB covers subjects from chemistry, pharmacy, biology, physics over to engineering. The journal focuses on the preparation, performance and use of functional biomaterials in biomedical devices and their behaviour in physiological environments. Our aim is to encourage scientists to publish their results in as much detail as possible. Therefore, there is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Several topical special issues will be published. Scope: adhesion, adsorption, biocompatibility, biohybrid materials, bio-inert materials, biomaterials, biomedical devices, biomimetic materials, bone repair, cardiovascular devices, ceramics, composite materials, dental implants, dental materials, drug delivery systems, functional biopolymers, glasses, hyper branched polymers, molecularly imprinted polymers (MIPs), nanomedicine, nanoparticles, nanotechnology, natural materials, self-assembly smart materials, stimuli responsive materials, surface modification, tissue devices, tissue engineering, tissue-derived materials, urological devices.
