The regeneration of periodontal bone defects continues to be an essential therapeutic concern in dental biomaterials. Numerous biomaterials have been utilized in this sector so far. However, the immune response and vascularity in defect regions may be disregarded when evaluating the effectiveness of biomaterials for bone repair. Among several regenerative treatments, the most recent technique of in situ tissue engineering stands out for its ability to replicate endogenous restorative processes by combining scaffold with particular growth factors. Regenerative medicine solutions that combine biomaterials/scaffolds, cells, and bioactive substances have attracted significant interest, particularly for bone repair and regeneration. Dental stem cells (DSCs) share the same progenitor and immunomodulatory properties as other types of MSCs, and because they are easily isolable, they are regarded as desirable therapeutic agents in regenerative dentistry. Recent research has demonstrated that DSCs sown on newly designed synthetic bio-material scaffolds preserve their proliferative capacity while exhibiting increased differentiation and immuno-suppressive capabilities. As researchers discovered how short peptide sequences modify the adhesion and proliferative capacities of scaffolds by activating or inhibiting conventional osteogenic pathways, the scaffolds became more effective at priming MSCs. In this review, the many components of tissue engineering applied to bone engineering will be examined, and the impact of biomaterials on periodontal regeneration and bone cellular biology/molecular genetics will be addressed and updated.
牙周骨缺损的再生仍然是牙科生物材料中一个至关重要的治疗关注点。迄今为止,已经有许多生物材料在该领域得到了应用。然而,在评估生物材料对骨修复的有效性时,可能会忽略缺陷区域的免疫反应和血管生成。在几种再生治疗方法中,最近的原位组织工程技术因其能够通过将支架与特定生长因子结合来复制内源性修复过程而脱颖而出。结合生物材料/支架、细胞和生物活性物质的再生医学解决方案引起了人们的极大兴趣,特别是在骨修复和再生方面。牙源性干细胞(DSCs)与其他类型的间充质干细胞具有相同的祖细胞和免疫调节特性,并且由于它们易于分离,因此被认为是再生牙科中理想的治疗剂。最近的研究表明,播种在新设计的合成生物材料支架上的 DSCs 保持其增殖能力,同时表现出增强的分化和免疫抑制能力。随着研究人员发现短肽序列如何通过激活或抑制传统成骨途径来改变支架的粘附和增殖能力,支架在启动间充质干细胞方面变得更加有效。在这篇综述中,将检查应用于骨工程的组织工程的许多组成部分,并讨论和更新生物材料对牙周再生和骨细胞生物学/分子遗传学的影响。
