tooth pulp

Nd: YAG laser with light guide fibre exporting had been used to deal of canine tooth pulp and made relevant observation of histology.

应用Nd：YAG激光经0.5mm光导纤维输出对犬牙髓进行处理和相应的组织学观察。

Objective To investigate the effects of different pulp treatment for replanted tooth.

目的探讨脱位再植牙牙髓治疗的最佳方法。

Analytical investigation on the clinical effect of devitalization of tooth pulp of the Chinese traditional remedy

中药牙髓失活剂的临床疗效分析

Young permanent tooth and deciduous tooth which have high pulp horn.

青少年的恒牙和儿童的乳牙,因其髓角位置高不宜作嵌体,以免损伤牙髓.

The discovery would possibly be beneficial to continuous development of the root of young permanent tooth with dental pulp necrosis and apical periodontitis after appropriate treatment.

这一发现可能有利于根尖未发育完成的年轻恒牙发生牙髓坏死以及由此引起的根尖周炎经适当的治疗后牙根的继续发育。

Method: Model of rat tooth injury was established to examine actin in the healthy pulp and the pulps from 2 hours to 14 days after burred by immunohistochemical technique.

方法：建立大鼠磨牙牙髓损伤模型，用免疫组化方法观察正常牙髓及钻磨后2h～14d牙髓中肌动蛋白的分布情况。

Results: NF-kB positive signals were observed in the osteoclasts up to the permanent tooth germ and in odontoclasts in the medial wall of the pulp cavity of deciduous teeth.

结果：NF kB在幼犬替牙期的恒牙胚上方骨组织中的破骨细胞以及乳牙根面和牙髓腔内的破牙细胞中均有阳性信号表达。

Methods: A right handed patient with cold stimulated dentinalgia of the first right maxillary bicuspid was selected to perform the fMRI study. Other tooth pulp disease and oral metal restoration were excluded.

方法：选取右利手右上颌第一双尖牙牙髓冷刺激痛患者1名，排除口内的其它牙髓病变及金属充填、修复体。

Dentin non-collagenous proteins ( NCPs) play critical roles in odontoblast induction, differentiation and dentin mineralization, and they have become the research focus of the tooth developmental biology and dental pulp biology.

近年来，牙本质非胶原蛋白（Non-collagenous proteins，NCPs）在成牙本质细胞诱导分化和牙本质形成中作用的研究已成为牙齿发育生物学和牙髓生物学研究的热点。

Experimental Research on Canine Tooth Pulp with Nd: TAG Laser Radiation

Methods: To select 150 patients for root canal treatment, including hard tissue of tooth disease, pulpitis, periapical periodontitis, periodontal-pulp unite disease, teeth obscurity crack and injury of teeth, etc.

方法：选择150例牙体硬组织疾病、牙髓炎、根尖周炎、牙周牙髓联合病、牙齿隐裂及外伤等原因而需进行根管治疗的患牙，分成3组进行根管预备。
