这项研究评估了牙科修复材料的机械性能和配方,该材料由水葫芦的醋酸纤维素(CA)和白虾壳的壳聚糖(C)组成。研究阶段包括提取,配方,功能组测试,抗菌,毒性,吸水性和溶解性,压缩,剪力,拉伸,硬度,微泄漏,热膨胀,和收缩。实验数据采用probit回归分析,单向方差分析,和Kruskal-Wallis测试.数据显示,CA和C具有microxyl和胺基,可以抑制S.mutans,并且无毒。复合树脂分为九种不同浓度的配方:F1(1%CA+3%C),F2(1%CA+5%C),F3(1%CA+7%C),F4(3%CA+3%C),F5(3%CA+5%C),F6(3%CA+7%C),F7(5%CA+3%C),F8(5%CA+5%C),和F9(5%CA+7%C)。F9的机械强度接近对照组,吸收113.33μg/mm3,80μg/mm3溶解度,32.67Mpa抗压强度,17.18Mpa抗拉强度,没有收缩。这表明F9具有作为生态友好型牙科填充材料的潜力。本研究通过结合水葫芦纤维和虾皮壳聚糖完成了修复材料配方的开发。对合成复合树脂和含有虾皮壳聚糖的水葫芦纤维复合材料的机械性能进行比较分析的结果表明,F9配方(CA5%C7%)表现出以下纤维:吸收,抗压强度,抗拉强度,硬度,和热膨胀。
This study evaluates the mechanical properties and formulation of dental restoration material comprised of cellulose acetate (CA) from water hyacinth and chitosan (C) from white shrimp shells. The research phases included extraction, formulation, functional group testing, antibacterial, toxicity, water absorption and solubility, compressive, shear, tensile, hardness, microleakage, thermal expansion, and shrinkage. The experimental data were analyzed using probit regression, one-way ANOVA, and Kruskal-Wallis test. The data showed that CA and C had microxyl and amine groups, could inhibit S. mutans, and were non-toxic. Composite resins were divided into nine formulations with different concentrations: F1 (1 % CA + 3 % C), F2 (1 % CA + 5 % C), F3 (1 % CA + 7 % C), F4 (3 % CA + 3 % C), F5 (3 % CA + 5 % C), F6 (3 % CA + 7 % C), F7 (5 % CA + 3 % C), F8 (5 % CA + 5 % C), and F9 (5 % CA + 7 % C). The F9 has mechanical strength close to the control group, with 113.33 μg/mm3 absorption, 80 μg/mm3 solubility, 32.67 Mpa compressive strength, 17.18 Mpa tensile strength, and no shrinkage. It shows that F9 has potential as an eco-friendly dental filling material. The present study completed the development of a formulation for a restoration material by combining water hyacinth fiber and shrimp skin chitosan. The outcomes of a comparative analysis of the mechanical properties of synthetic composite resins and water hyacinth fiber composites containing shrimp skin chitosan revealed that the F9 formulation (CA 5 % + C 7 %) exhibited the following fiber: absorption, compressive strength, tensile strength, hardness, and thermal expansion.
