牙骨质

The above results revealed that the combining application of EMPs and e-PTFE membrane could significantly promote the treatment of furcation defects.

上述结果表明：EMPs与eITFE膜联合应用可明显促进人工根分叉部位牙周组织缺损的愈合，尤其是无细胞性牙骨质的再生。

RESULTS: Before remineralization, through SEM, short blunt eeptoma was found on the surface of lesions of samples in Chinese nutgall group and Ag（ NH3 ）2F group; while in NaF group, globular ecptoma was seen scattering on the surface of the lesions, together with laeune; in deionized group, there was Sharpey＇s fiber.

结果：再矿化前，扫描电镜观察五倍子与氟化氨银处理后牙骨质龋表面形成不规则短钝状突起；氟化钠液组形成大小不一的散在大球状突起，可见一些腔隙存在；去离子水组大量分布夏伯氏纤维。

RESULTS: BMP-2 was mainly found in the plasma of fibroblast, osteoblast, cementocyte, odontoblast separately.

结果：牙周膜成纤维细胞、成骨细胞、成牙骨质细胞及胶原纤维中均可见BMP-2阳性染色。

For each subject, the buccolingual bone thickness was measured by postulating that the miniscrews would be inserted at 16 positions (10, 12, 14 and 16 mm above the median sagittal planes of the interradicular spaces between the first molars and the second premolars in the maxilla, and 30°, 45°, 60°, 90° from the cortical bone surface).

在重建后的锥形线束CT影像上测量上颌第二前磨牙与第一磨牙牙根间矢状面上距离参考平面10，12，14，16 mm的4个植入高度上，以与骨皮质表面成30°，45°，60°，90°的4个方向共16个部位的颊舌侧骨质厚度，计算各植入部位触及上颌窦的危险率，在骨厚度大于6 mm的植入部位模拟植入微螺钉种植体并测量其周围骨质密度。

The extract of cemental matrix can enhance the initial attachment of HGF and HPC on the root surface.

牙骨质基质提取物能够促进牙周膜细胞在牙根表面上的附着。

Results: The extract of cemental matrix could enhance the initial attachment of human gingival fibroblasts and human periodontal cells to the surface of root, and such effects were strengthened with increasing density and time.

且牙骨质基质提取物促牙周膜成纤维细胞附着的作用高于对牙龈成纤维细胞的作用。

The immunohistochemical location of noncollagenous protein, bone sialoprotein , osteopontin and osteocalcin at different stages following periradicular surgery was undertaken. The crystals formation on surfaces of MTA was evaluated when treated in different conditions without cells in vitro and in vivo. MTA was used to manage clinical problems, including perforations in roots or furcations, and pulpless permanent teeth with incomplete root formation. The study included the following three parts

本研究试图通过体内外研究探讨MTA表面牙骨质形成的机理，动物体内动态观察根尖周组织在用MTA倒充填后的组织反应和细胞外基质非胶原蛋白的表达，体外观察MTA在不同的环境下表面的形态及成分变化，和在体内环境下材料表面磷灰石层的形成，同时结合临床病例观察其临床治疗效果。

Cell sheet transplantation regenerated both new bone and cementum connecting with well-oriented collagen fibers, while only limited bone regeneration was observed in control group where cell sheet transplantationwas eliminated.

结果发现，细胞膜片移植再生出了新骨、牙骨质以及连接二者的排列整齐的胶原纤维，而在没有进行细胞膜片移植的对照组只观察到了有限的骨再生。

AIM: To analyze the apoptosis and proliferation of HERS (Hertwig's epithelial root sheath) and to evaluate the roles of HERS cells in the development of cementum.

目的：观察牙根发育中上皮根鞘细胞(Hertwig's epithelial root sheath， HERS)断裂后结局和增殖凋亡相关基因的表达，探讨上皮根鞘在牙根发育特别是牙骨质形成中的可能作用。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
