dentin 牙本质(0) 目前没有对本词条修改信息

牙本质     composite resin penetrated into the hollows, forming lots of resin tags. Parameters of 50μm size particles at 120-160 psi(for enamel) and 100-120 psi(for dentin) were the best for use.     在所使用的参数中，以50μm颗粒直径、120～160psi气压（牙釉质）、100～120psi气压（牙本质）最为合适。 短句来源     Results The surfaces of enamel and dentin demonstrated dense and irregular concave and convex structure;     结果：牙釉质和牙本质表面均形成密集不规则的凹凸结构，树脂渗入这些结构形成许多树脂突。 短句来源   “dentin”译为未确定词的双语例句     A Preliminary Study of Air-Abrasion Cavity Preparation Effects on Surfaces of Enamel and Dentin.     空气喷磨处理牙面的初步研究 短句来源     Conclusion The results of this study suggested that KCP can excavate dental surfaces effectively and can be used in preparing bonding surfaces of enamel and dentin in lieu of acid etching.     结论：本实验提示空气喷磨能有效蚀刻牙体表面，可以替代酸蚀用于牙面的处理。 短句来源 查询“dentin”译词为用户自定义的双语例句     我想查看译文中含有：的双语例句

Objective To investigate the morphological changes of enamel and dentin abrased with air-abrasion cavity preparation(KCP). Methods The teeth surfaces were abrased under different ain pressures and with variant particle sizes, then bonded with composite resin. The morphological changes on the abrased surfaces of the teeth and on the corresponding surfaces of the resin left after the teeth were dissolved by acid were observed under SEM. Results The surfaces of enamel and dentin demonstrated... Objective To investigate the morphological changes of enamel and dentin abrased with air-abrasion cavity preparation(KCP).

目的：应用空气喷磨处理新鲜离体牙的牙釉质和牙本质表面，观察所引起的形态改变。方法：用不同的气压和颗粒直径喷磨牙齿表面，然后进行树脂粘结，扫描电镜观察牙釉质和牙本质的喷磨面及树脂粘结面的形态特征。结果：牙釉质和牙本质表面均形成密集不规则的凹凸结构，树脂渗入这些结构形成许多树脂突。在所使用的参数中，以５０μｍ颗粒直径、１２０～１６０ｐｓｉ气压（牙釉质）、１００～１２０ｐｓｉ气压（牙本质）最为合适。结论：本实验提示空气喷磨能有效蚀刻牙体表面，可以替代酸蚀用于牙面的处理。

目的：探讨风湿性心脏病并发房颤的临床特点，为临床治疗提供指导。方法：对１０６例风湿性心脏病（风心病）并发房颤病人与同期８９例风心病窦性心律病人（对照组）的临床资料及彩色多普勒超声心动图资料进行对比分析。结果：房颤组较对照组年龄大、病程长、左房内径及右室内径大、左室壁较厚、瓣膜钙化多、继发性三尖瓣关闭不全例数多、发生脑栓塞例数多，两组差别具有统计学意义。结论：为改善风心病并发房颤患者的预后，对上述临床特点应予以足够重视，并采取更积极的措施防治房颤。
