  periodontal regeneration
To date, various conventional therapies for periodontal regeneration have shown limited and variable clinical outcomes.
      
Periodontal ligament cells (PDL) are thought to play a major role in promoting periodontal regeneration.
      
Within the limits of the present study, it can be concluded that OCHS may favor periodontal regeneration in acute-type intrabony periodontal defects.
      
The OCHS-treated defects consistently revealed periodontal regeneration (i.e., new periodontal ligament, new cementum with inserting collagen fibers, and new bone).
      
In the control group, healing was predominantly characterized by the formation of a long junctional epithelium along the root surface and limited periodontal regeneration at the most apical part of the defect.

Objective:Some research suggested that enamel matrix proteins(EMPs) not only induced formation of cementum, but also could promote regeneration of periodontal tissue and alveolar bone. In order to recognize the mechanisms of periodontal regeneration induced by EMPs and provide a basic data for further study, influences of EMPs on osteoblast proliferation and differentiation are explored in this study.Methods:Porcine enamel matrix proteins were extracted by using acetic acid. MC3T3 E1 osteoblasts were...

Objective:Some research suggested that enamel matrix proteins(EMPs) not only induced formation of cementum, but also could promote regeneration of periodontal tissue and alveolar bone. In order to recognize the mechanisms of periodontal regeneration induced by EMPs and provide a basic data for further study, influences of EMPs on osteoblast proliferation and differentiation are explored in this study.Methods:Porcine enamel matrix proteins were extracted by using acetic acid. MC3T3 E1 osteoblasts were selected and cell culture was used in vitro. EMPs with different concentrations of 50μg/ml, 100μg/ml and 150μg/ml were added separately in α MEM culture medium and compared with negative group and positive group (TGF β\-1). The count of cell was recorded after 0,1,2,3,4,5,6 days, then the data were analysed satistically by using SAS.Results: The cell count of all EMPs groups were higher than that in the negative control group (P<0 01), 100μg/ml as well as 150μg/ml EMPs groups were higher than the positive group(TGF β\-1) on the second day (P<0 01). The cell count of 100μg/ml EMPs group was not only higher than C and T groups, but also higher than that of other EMPs dose groups on the fifth day.Conclusion: The proliferation and differentiation of osteoblasts can be promoted distinctly by enamel matrix proteins.\;

目的:观察评价生长因子-支架构建方式的组织工程方法对牙周组织再生修复的影响和意义,探讨纳米羟基磷灰石材料(nHAC)和重组人骨形成蛋白 -2 (rhBMP-2 )用于牙周组织工程的可行性。方法:将rhBMP-2与nHAC复合植入动物人工牙周组织缺损,表面覆盖聚四氟乙烯(e-PTFE)膜,以空白对照组和单纯GTR组作为对照。术后 8周进行组织学观察和测量,分析评价其牙周组织的再生情况。结果:rhBMP-2-nHAC-膜复合植入组较空白对照组和单纯GTR组有更多的新生牙槽骨、新生牙周膜和新生牙骨质生成,且未见上皮长入。结论:应用生长因子-支架构建方式的牙周组织工程方法能更有效地促进牙周组织再生和重建,而rhBMP-2和nHAC有望用作牙周组织工程的生长因子和支架材料。
