Choosing Jining ancient canal as the point to start, the paper introduces the research content, methods, background and framework, illustrates the related concepts and the connotation in the first. 以济宁古运河为切入点,本文首先介绍了研究背景、内容、方法和框架,阐述了相关概念和内涵。
The distance between mandibular canal and root point at mandibular molar area decreased gradually from forth to back. The display ratio of both margins of mandibular canal was 68 %, only lower margin 28 %, none 4 %. 磨牙区下颌管与牙根尖距离从前向后逐渐减少,下颌神经管显现率从后向前逐渐降低,上下壁全部显现68%,下壁显现28%,不显现4%。
Two straight lines were drawn from the canal orifice to the point where the file deviated from the canal. 分别连接根管口至K型锉偏离根管长轴点,测量两连线的夹角,即根管交叉角度。
Conclusion The deep layer of transverse fascia was weaker than superficial layer in these corpses. To strengthen and reconstruct the posterior wall of inguinal canal was the key point in the clinical repair of inguinal hernia ( IH ). 结论腹横筋膜深层较浅层薄弱,加强和重建腹股沟管后壁是腹股沟疝手术成败的关键。
Method CPC and traditional root canal filling paste gutta percha point were used in treament of root canal filling on 120 roots. The cases were followed up for 1 ~ 2 years. 方法:采用自固化磷酸钙根管充填剂和传统的充填剂分别应用于随机选择的两组做根管治疗的患牙随访观察1~2年。
