A novel approach to enhancing the mechanical properties of glass-ionomer cement (GIC) may incorporate natural fiber. This study aims to evaluate the effects of raw and pure hemp fiber additions on the flexural strength (FS) and surface roughness (SR) properties of glass-ionomer cement (GIC).
Hemp fibers sourced from the local population were harvested, dried, and separated, then prepared in raw and pure forms to assess their impact on the FS and surface roughness of GIC. Synthesized GICs dopped raw and pure hemp fiber were characterized using SEM and EDX for morphological and elemental analysis. The mechanical features of GICs were measured using an FS and SR testing apparatus.
Raw hemp fibers, known for their sustainability and mechanical resilience, showed significant enhancements in FS, particularly at 1% addition. High FS and SR values using pure fibers at 1% and 3% concentrations were due to improving fiber-matrix interactions, reducing the cracks on GICs. SEM analysis of fracture surfaces supported these findings, showing fiber reinforcement at crack lines.
This approach offers a promising, eco-friendly, cost-effective alternative for dental restorations, combining mechanical durability and surface quality. These results highlight the potential of hemp fiber-reinforced GIC in advancing sustainable, restorative materials in dentistry.
一种增强玻璃离子水门汀（GIC）机械性能的新方法可能涉及天然纤维。本研究旨在评估添加未加工和纯麻纤维对玻璃离子水门汀（GIC）的抗弯强度（FS）和表面粗糙度（SR）性能的影响。
采集当地的麻纤维，进行干燥和分离，然后制成未加工和纯的形式，以评估它们对GIC的FS和表面粗糙度的影响。使用扫描电子显微镜（SEM）和能量色散X射线光谱仪（EDX）对添加了未加工和纯麻纤维的合成GIC进行形态和元素分析。使用FS和SR测试仪器测量GIC的机械性能。
以其可持续性和机械韧性著称的未加工麻纤维在FS方面有显著提高，尤其是添加量为1%时。在1%和3%浓度下使用纯纤维时，FS和SR值较高是由于改善了纤维与基体的相互作用，减少了GIC上的裂缝。对断裂表面的SEM分析支持了这些发现，显示在裂纹线处有纤维增强。
这种方法为牙科修复提供了一种有前景、环保且经济高效的替代方案，兼具机械耐久性和表面质量。这些结果突出了麻纤维增强GIC在推进牙科可持续修复材料方面的潜力。
