Biodentine, a calcium silicate-based material, is known for its biocompatibility and ability to promote dentin regeneration. With their unique branching structure, polyamidoamine (PAMAM) dendrimers have shown promise in facilitating biomimetic remineralization processes.
This study investigates the synergistic effects of combining PAMAM with Biodentine on root dentin remineralization, aiming to develop a novel bioactive compound that offers superior protective and regenerative properties.
The following predictions were made: (1) In a cyclic artificial saliva/acid regimen, among the test groups, the combination of Biodentine and PAMAM would cause the most root dentin remineralization (2). Biodentine alone would increase Ca and P concentrations, neutralize acid, and promote root dentin remineralization (3). PAMAM, on the other hand, can remineralize the demineralized root dentin.
Minimal mineral regeneration was accomplished in demineralized root dentin when treated with Biodentine or PAMAM alone. Root dentin remineralization was most pronounced when Biodentine and PAMAM were used together, and the hardness of demineralized root dentin was raised to an equivalent level to that of healthy root dentin.
The study demonstrated the exceptional ability of PAMAM + Biodentine to promote root dentin remineralization. In an acid-challenging environment, PAMAM + Biodentine promoted full and efficient root dentin remineralization. Restorations made using innovative PAMAM + Biodentine technology show promise in remineralizing and protecting tooth structures.
生物活性玻璃陶瓷(Biodentine)是一种基于硅酸钙的材料,以其生物相容性和促进牙本质再生的能力而闻名。聚酰胺-胺(PAMAM)树枝状大分子具有独特的分支结构,在促进仿生矿化过程中显示出前景。
本研究调查PAMAM与生物活性玻璃陶瓷(Biodentine)联合使用对牙根牙本质再矿化的协同作用,旨在开发一种具有卓越保护和再生性能的新型生物活性化合物。
做出以下预测:(1)在循环人工唾液/酸方案中,在测试组中,生物活性玻璃陶瓷(Biodentine)和PAMAM的组合将导致最多的牙根牙本质再矿化(2)。单独使用生物活性玻璃陶瓷(Biodentine)会增加钙和磷的浓度,中和酸,并促进牙根牙本质再矿化(3)。另一方面,PAMAM可以使脱矿的牙根牙本质再矿化。
单独用生物活性玻璃陶瓷(Biodentine)或PAMAM处理脱矿的牙根牙本质时,实现的矿物再生极少。当生物活性玻璃陶瓷(Biodentine)和PAMAM一起使用时,牙根牙本质再矿化最为明显,脱矿牙根牙本质的硬度提高到与健康牙根牙本质相当的水平。
该研究证明了PAMAM +生物活性玻璃陶瓷(Biodentine)促进牙根牙本质再矿化的卓越能力。在酸性挑战环境中,PAMAM +生物活性玻璃陶瓷(Biodentine)促进了完全且有效的牙根牙本质再矿化。使用创新的PAMAM +生物活性玻璃陶瓷(Biodentine)技术进行的修复在使牙齿结构再矿化和保护方面显示出前景。
