Abstract

The purpose of this study was to prepare cellulose fibers decorated with titanium dioxide, and then incorporate them into the formulation of dental adhesive composites. The influence of this filler on the mechanical, chemical, and biological characteristics of the composites was examined. Different proportions of the filler were mixed with the monomers and then the prepared materials were analyzed through chemical, mechanical, and microscopic characterization. Biocompatibility tests were performed using fibroblast cell lines. Mechanical characterization included the hardness test, the biaxial flexural strength (BFS) test, and the shear bond strength test (SBT). The fillers were found biocompatible, as suggested by the Alamar blue assay, while the mechanical properties of the composites increased with higher filler content. The experimental composite presented good mechanical and biological properties, and thus, it can be used as a dental adhesive material.

TiO2装饰纤维素材料的添加对牙胶复合材料力学性能和生物性能的影响

本研究的目的是制备二氧化钛修饰的纤维素纤维，然后将其掺入牙科粘合剂复合材料的配方中。研究了这种填料对复合材料的力学、化学和生物特性的影响。将不同比例的填料与单体混合，然后通过化学、机械和微观表征对制备的材料进行分析。使用成纤维细胞系进行生物相容性测试。机械表征包括硬度测试、双向弯曲强度（BFS）测试和剪切结合强度测试（SBT）。Alamar蓝分析表明，填料具有生物相容性，而复合材料的机械性能随着填料含量的增加而增加。实验复合材料具有良好的力学性能和生物性能，可作为牙科粘接材料。
