This study aimed to enhance conventional glass ionomer cement (GIC) by incorporating 15 % chitosan, 5 % bovine serum albumin (BSA), 0.05 % tricalcium phosphate (TCP), and 1 μg translationally controlled tumor protein (TCTP), resulting in an enhanced-GIC formulation. The study evaluated its adhesion properties, biocompatibility, and ability to promote pulp tissue healing in rabbit anterior teeth.
The enhanced-GIC was tested in a rabbit model to assess its physical adhesion and biological effects on pulp tissue. Following cavity preparation and material placement, the teeth were observed for 21 days. Histological evaluations focused on inflammation, toxicity, and collagen synthesis in pulp tissue.
The enhanced-GIC showed comparable adhesion properties to conventional GIC. Histological analysis revealed no significant inflammation or toxicity in the pulp tissue of either group. The enhanced-GIC group exhibited superior biocompatibility, demonstrated by increased lymphocyte infiltration and enhanced collagen synthesis within the pulp tissue, suggesting its potential for promoting tissue regeneration.
The enhanced-GIC formulation shows promise as a sublining material in restorative dentistry, offering benefits in pulp tissue healing and collagen formation, while maintaining adhesion comparable to conventional GIC. This study highlights enhanced-GIC's potential for use in dental restorative procedures, particularly for cases requiring pulp regeneration.
本研究旨在通过加入15%的壳聚糖、5%的牛血清白蛋白(BSA)、0.05%的磷酸三钙(TCP)和1μg的翻译调控肿瘤蛋白(TCTP)来增强传统玻璃离子水门汀(GIC),从而得到一种增强型GIC配方。该研究评估了其在兔前牙中的黏附特性、生物相容性以及促进牙髓组织愈合的能力。
在兔模型中对增强型GIC进行测试,以评估其对牙髓组织的物理黏附性和生物学效应。在制备窝洞并放置材料后,观察牙齿21天。组织学评估重点关注牙髓组织中的炎症、毒性和胶原蛋白合成。
增强型GIC显示出与传统GIC相当的黏附特性。组织学分析表明,两组牙髓组织中均无明显炎症或毒性。增强型GIC组表现出更好的生物相容性,表现为牙髓组织内淋巴细胞浸润增加和胶原蛋白合成增强,表明其具有促进组织再生的潜力。
增强型GIC配方有望作为修复牙科中的衬层材料,在牙髓组织愈合和胶原蛋白形成方面具有优势,同时保持与传统GIC相当的黏附性。本研究突出了增强型GIC在牙科修复手术中的应用潜力,特别是在需要牙髓再生的病例中。
