概括
干细胞疗法在治疗牙周炎方面表现有前途,改善了临床附着水平和口袋深度. 需要进一步的高质量研究来证实这些对牙周再生的好处.
科学领域:
- 牙周医学和再生牙科.
- 用于口腔健康的生物材料和组织工程.
背景情况:
- 牙周炎会导致牙支组织的不可逆转破坏和牙损失.
- 目前对干细胞治疗在牙周再生中的作用的理解仍然有限.
- 目前正在探索中细胞干细胞在牙周炎治疗中的临床应用.
研究的目的:
- 系统地评估基于干细胞的疗法的疗效,与用于牙周再生的无细胞疗法相比.
- 综合来自随机对照试验 (RCT) 关于牙周炎干细胞治疗的证据.
- 评估干细胞治疗对关键牙周再生参数的影响.
主要方法:
- 在2023年6月,在多个数据库 (PubMed,CENTRAL,WOS,Embase,Scopus,Wanfang,CNKI) 进行了全面的文献搜索.
- 包括的研究是RCT,比较基于干细胞的治疗与治疗无细胞的牙周炎,至少六个月的随访.
- 使用Review Manager 5.4进行了元分析,并使用GRADEpro GDT评估了偏差风险和证据水平.
主要成果:
- 五项RCT (118名患者) 的分析表明,基于干细胞的治疗显著改善了临床附着水平 (CAL),口袋探测深度 (PPD) 和骨到缺陷底部 (BC-BD).
- 具体来说,CAL显示平均差异 (MD) 为-1.18 (P < 0.00001),PPD显示MD = -0.75 (P = 0.020),而BC-BD显示MD = -0.95 (P = 0.010).
- 干细胞治疗对牙衰退或从水泥合点到缺陷底部的距离没有显著影响.
结论:
- 基于干细胞的治疗表明,在牙周炎治疗中对CAL,PPD和BC-BD有潜在的益处.
- 目前的证据因包含的研究数量少而有限,需要进一步验证.
- 未来的研究应该专注于高质量的,大规模的,多中心的RCT,使用标准化的协议来确定最终的疗效.

Stem Cell Therapy for Tissue Regeneration
4.1K
Stem cell therapy is a method used in regenerative medicine to repair and restore function to damaged tissues and organs. Stem cells have the potential to proliferate and differentiate into various tissue types, making them ideal candidates for tissue regeneration. For example, hematopoietic stem cell transplants are commonly used in blood cancer treatment to replenish damaged bone marrow and restore healthy blood cells.

Mesenchymal Stem Cells
4.8K
Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...
