Abstract

(1) Background: Bond strength between repair and restorative materials is crucial for endodontic success. This study assessed the effects of the following final irrigation solutions on the bond strength of mineral trioxide aggregate (MTA) to a bulk-fill composite: (1) 17% Ethylenediamine tetraacetic acid (EDTA); (2) 2% Chlorhexidine (CHX); (3) 0.2% chitosan; (4) 0.2% chitosan with 2% CHX; 5) 0.2% chitosan with AgNPs. (2) Methods: Sixty MTA samples were divided into six groups (n = 10) based on the final irrigation solution: 1. EDTA, 2. CHX, 3. Chitosan, 4. Chitosan-CHX, 5. Chitosan-AgNP, and 6. distilled water (control). After a 5-min solution exposure, each sample was restored with the bulk-fill composite, and the shear bond strength (SBS) was measured. Structural changes in MTA were analyzed using SEM and EDS, and failure modes were classified as adhesive, cohesive, or mixed. Data were analyzed by one-way ANOVA with Tamhane's T2 and Tukey's tests (α = 0.05). (3) Results: EDTA exhibited the lowest SBS (p < 0.001), while Chitosan-CHX showed the highest. SEM showed a spongy, void-rich surface in EDTA-treated MTA, with significant Ca depletion per EDS. Chitosan-CHX showed no structural change. Cohesive fractures within MTA were predominant. (4) Conclusions: EDTA significantly reduces SBS, while chitosan with CHX enhances bond strength.

壳聚糖基灌溉液对三氧化矿物骨料与堆填复合材料粘结强度影响的评价。

(1)背景：修复体与修复体之间的粘结强度是根管治疗成功的关键。本研究评估了以下最终灌溉溶液对矿物三氧化物骨料（MTA）与块体填充复合材料结合强度的影响：(1)17%乙二胺四乙酸（EDTA）；(2) 2%氯己定（CHX）；(3) 0.2%壳聚糖；(4) 0.2%壳聚糖加2% CHX；5) 0.2%壳聚糖加AgNPs。(2)方法：60份MTA样品根据最终灌洗液分为6组（n = 10）： 1. MTA样品的灌洗液；EDTA, 2。CHX 3。壳聚糖4。Chitosan-CHX 5。壳聚糖agnp；蒸馏水（对照）。溶液暴露5分钟后，每个样品用块体填充复合材料修复，并测量剪切粘结强度（SBS）。利用扫描电镜和能谱仪分析了MTA的结构变化，并将其破坏模式分为粘接、内聚和混合。数据采用Tamhane’s T2检验和Tukey’s检验进行单因素方差分析（α = 0.05）。(3)结果：EDTA的SBS最低（p < 0.001）， Chitosan-CHX最高。扫描电镜显示，经edta处理的MTA表面呈海绵状，富含空隙，能谱图显示明显的Ca损耗。壳聚糖chx未见结构变化。MTA内聚性骨折居多。(4)结论：EDTA能显著降低SBS，壳聚糖加CHX能增强结合强度。

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.
