Furcation morphology of 103 permanent molar teeth(only first and second molars)in human has been observed by the measuring methods to evaluate whether furcation morphology mayinfluence the periodontal treatment by using curettage. It was shown that the buccal furcation demension(of angle)of maxillary teeth tended to be smaller than either themesiopalatal or distopalatal,and so did the mesiodistal furcation demension of mandibular, teeth.Furthermore,the blade face diameter of the domestic curettes...

Furcation morphology of 103 permanent molar teeth(only first and second molars)in human has been observed by the measuring methods to evaluate whether furcation morphology mayinfluence the periodontal treatment by using curettage. It was shown that the buccal furcation demension(of angle)of maxillary teeth tended to be smaller than either themesiopalatal or distopalatal,and so did the mesiodistal furcation demension of mandibular, teeth.Furthermore,the blade face diameter of the domestic curettes is usually too wide to enter furca tion, which makes it unlikely that curette used-alone will achieve adequate preparation of this area according to the routine procedures,It was also found that there are almost always concavities on the mesiobuCcal furcal aspect Of maxillary teeth and on mesial and distal furcal aspect of mandibular teeth,The maximal depth ofthese concavities is up to 2mm.The results may be considered to be one of the important reasons wh-y furcation involvement is not easy to eliminate.

本文对103枚人类恒磨牙(第一、二恒磨牙)根分叉部形态进行了测量观察,旨在探讨其对牙周治疗的影响。结果表明,上颌近-选中颊根和下颌近-远中根根分叉角度小于上颌近中颊-腭根或远中颊腭根根分叉角度。又由于国产龈下刮治器的工作面直径较宽,当根分叉角度较小时,器械到达根分叉部受限。因此,按照常规方法常难以对根分叉部进行良好的根面预备。此外,本研究还发现人类多根牙的根面沟凹陷出现率很高,上颌牙近中颊根和下颌牙近、远中根几乎总存在根面沟凹陷,且最大深度可达2mm,因此认为,其可能是根分叉部病变难以彻底消除的重要原因之一。

Supraeruption of the molars in the absence of antagonist molars or without occlusal contacts was observed in a miniature pig. Tetracycline was used to label the new regenerated cementum and alveolar bone associated with the supraeruption. The results showed that the molar through root canal treatment migrated the same level as the molars with pulp, which means that the hydrodynamic and hydrostatic forces arising from the blood in pulp vessels look doubtful. Cementum and alveolar bone deposition was seen around...

Supraeruption of the molars in the absence of antagonist molars or without occlusal contacts was observed in a miniature pig. Tetracycline was used to label the new regenerated cementum and alveolar bone associated with the supraeruption. The results showed that the molar through root canal treatment migrated the same level as the molars with pulp, which means that the hydrodynamic and hydrostatic forces arising from the blood in pulp vessels look doubtful. Cementum and alveolar bone deposition was seen around the apical, cervical regions and under the furcation area. The thickness of the deposition layers was almost the same as the supraerupted volume from the model measurement.

为了研究能造成病理损害与修复困难的牙过萌现象,通过拔牙、调磨等方法在小型猪口内建立了牙过萌的动物模型并进行了过萌量的观测和组织学观察研究。结果表明,牙髓血管内血流的流体力学与静力学效应为零时,该牙的过萌量并不少于相同条件下牙髓健康牙齿的过萌量,从而对“BVT(bloodvesselthrust)假说”中有关牙髓内血流的力学效应是造成过萌的观点提出了质疑;平衡力系被打破后,丧失对接触的牙均发生了过萌,而不论其是否作过牙髓处理;牙槽骨新生骨质的沉积量明显较新生牙骨质者大,前者大于后者的8倍,根尖区、根分歧区与牙槽嵴顶区均有明显的新生骨沉积带,新生牙槽骨与新生牙骨质宽度之和约等于牙过萌的量。本研究结果对探讨牙过萌现象的机理有参考价值。

Objective To conserve mandibular prsterior residual roots and crowns as many as possible and to increase the conservative rate of the teeth. Methods Separating roots was used for the conservative prosthetics of 24 mandibular posterior teeth with furcation involvement. Results The successful rate of conservative prosthetics was 94% in the first mandibular molars, while 67% in the second molars. Conclusion As long as the furcation involvement was controled and the occlusal force was reduced,...

Methods Separating roots was used for the conservative prosthetics of 24 mandibular posterior teeth with furcation involvement. Results The successful rate of conservative prosthetics was 94% in the first mandibular molars, while 67% in the second molars. Conclusion As long as the furcation involvement was controled and the occlusal force was reduced, the conservative prosthetics could not only restore the morphology and function of the teeth, but also made it possible for some cases that could not be fixed prosthetic.

目的尽可能保存下颌后牙的残根残冠,提高患牙的保存率。方法对下颌后牙残根、残冠累及根分叉病变的24个患牙,采用分根法作保存修复。结果保存修复的成功率下颌第一恒磨牙为94%,第二恒磨牙为67%。结论只要控制根分叉感染,适当减小患牙的牙合力,保存修复不但能恢复患牙本身的形态和功能,尚能使一些不能做固定修复的病例变为可能。
