牙骨质

Methods: MTT and enzyme dynamics methods were used to observe the effects of CAP on cell proliferation and alkaline phosphatase activity of HDFC.

分别采用MTT比色法和酶动力学方法观察牛牙骨质附着蛋白对体外培养人牙囊细胞增殖及其碱性磷酸酶活性影响。

The hypoplasia or aplasia of root cementum was thought to be the prime etiological factor in the early loss of primary teeth.

认为牙根牙骨质形成不全或发育不良是该病患儿乳牙过早脱落的根本原因。

MAIN OUTCOME MEASURES: Each specimen was stained with hematoxylin and eosin. The lengths of new cementum and the area of new alveolar bone were calculated.

主要观察指标：苏木精-伊红染色观察并测量牙周组织再生(新生牙骨质长度和新生牙槽骨面积的百分比)情况。

Objective To evaluate the effect of enamel matrix protein on the attachment and proliferation of periodontal ligament cells on diseased cementum surfaces in vitro.

目的观察釉基质蛋白对牙周膜细胞在牙周炎患牙牙骨质根面上附着和增殖的影响。方法用EMP处理的牙周炎患牙根片为实验组，用生理盐水处理的患牙根片和健康牙根片分别作为对照。

Methods: 20 extracted human constant premolar were made into 20 dentine-samples and 20 cementum-samples.

将 2 0个健康离体人牙分别制成 2 0个牙本质和牙骨质标本。

He effect of antibiotics in inducing the formation of apices is to prevent infection of root canal, rather than direct induction. And TGF-β1 might act as an inductive factor in the cell differentiation of the above-mentioned cells.

GF-β1参与了尖周组织的修复过程，可能诱导了成牙本质样细胞、成牙骨质样细胞和骨样细胞的分化，在牙根继续形成中起着重要作用。

In a recent study, the researchers found that prolonged consumption of sports drinks may be linked to a condition known as erosive tooth wear, in which acids eat away the tooth's smooth hard enamel coating and trickle into the bonelike material underneath, causing the tooth to soften and weaken.

研究人员发现长期饮用运动饮料会导致腐蚀性的牙磨损，因为一些酸类会侵蚀牙齿表面光滑而坚硬的釉外壳并渗入内部的牙骨质，从而导致软化衰弱。

Conclusions】 EMPs and BMP-2 have the ability to induce HDFCs to differentiate toward an osteoblast or cementoblast phenotype.

EMPs、BMP-2可使牙囊细胞表型向成骨、成牙骨质样细胞分化。

Maxillary second molar has five subtype, Type A: absence of root fusion, Type B: presence of mesiobuccal and distobuccal root fusion, Type C: palatal root with anyone of buccal root fusion of molar with three roots, Type D:complete root fusion of molar with three roots, Type E:pseudofusion of molar.

分析其牙根发育沟之发生率、牙根发育沟之长度、牙根发育沟至牙骨质牙本质交界的距离，以及牙根发育沟最深点的深度、占牙根长的位置、与到牙根根管的距离，并且将牙根分类为上颚第一大臼齿，仅一种分类。

The purpose of the study was to evaluate quantitatively PDLC attachment and proliferation to periodontally diseased human cementum and dentin after demineralizing with minocycline- HCl and EDTA.

以往关于用四环素族药物处理根面的研究，均是以牙本质为载体，而临床上牙周手术后与牙周膜细胞接触的界面主要是牙骨质表面。

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.

也许他们将在壶穴里消失
