Introduction Upper abdominal magnetic resonance(MR)imaging is appropriate for body composition analysis.111 Especially for individuals with obesity,it is of great value to quantify the hepatic proton density fat fraction(PDFF)and the amount of abdominal adipose tissue during clinical evaluation and for research on obesity-related *** results may be used to determine the optimal choice of surgical procedure and evaluate treatment *** artificial intelligence(Al)algorithms and systems have been developed for the automated measurement of body *** basis of Al development and application is to have uniform standards for clinical data acquisition and *** uneven quality ofMR images is one ofthe major obstacles to Al system development and analytical results.A standardized process of MR scanning and clinical data management is urgently needed.

根管冠部预处理对磨牙根管工作长度的影响

上海口腔医学 2004年第3期13卷 179-181页

作者：王青熊世江窦惠芹周荣娥山东大学口腔医院口腔内科山东济南250012

目的:探讨根管冠部预处理对磨牙根管工作长度测量的影响。方法:将47例成人牙髓炎患者的48颗磨牙随机分成2.,第1组为常规治疗组,共2.颗磨牙74个根管,常规去腐开髓,插入15#K型锉至根管内到根尖区感觉有明显阻力为止,标记,采用分角投照技... 详细信息

目的:探讨根管冠部预处理对磨牙根管工作长度测量的影响。方法:将47例成人牙髓炎患者的48颗磨牙随机分成2.,第1组为常规治疗组,共2.颗磨牙74个根管,常规去腐开髓,插入15#K型锉至根管内到根尖区感觉有明显阻力为止,标记,采用分角投照技术摄X线片。第2.为根管冠部预处理组,2.颗磨牙75个根管。暴露根管口后,先用Profile.062.#、2.#镍钛机用器械扩开根管口,预备根管颈1/3,再同样插针摄片,分别测量2.X线片上K锉尖端至根尖的距离。将资料进行Logistic单因素和多因素分析。结果:根管冠部预处理后磨牙根管工作长度测量的准确性较常规组有显著提高(P<0.05),K锉尖端至根尖的距离与年龄、性别、磨牙的位置无显著相关,而与颌位显著相关,上颌磨牙的准确性明显好于下颌磨牙(P<0.05)。结论:根管冠部预处理可提高磨牙根管工作长度测量的准确性。

目的:研究ZrP99铸钛包埋材料的铸模温度对铸造精度的影响。方法:利用代型模具,制作30个超硬石膏全冠预备体代型,并制作相应的全冠蜡型,随机分为5组,每组6个样本,其中4组为实验组,采用ZrP99铸钛包埋材料进行包埋,分别在铸模温度为600℃、450℃、300℃、150℃条件下进行铸造;另外一组为对照组,采用Titavest-CB包埋材料进行包埋,在铸模温度为600℃条件下进行铸造。利用显微图像分析技术,在实体显微镜下分别测量蜡型及相应的铸件边缘与代型肩台之间在标志点处的间隙,两者差值即代表铸造精度。采用t检验及单因素方差分析进行统计学处理。结果:Titavest-CB包埋材料组的铸造精度显著优于在不同铸模温度下ZrP99包埋材料组;当ZrP99包埋材料的铸模温度低于450℃时,随着温度升高,铸造精度显著提高。结论:ZrP99铸钛包埋材料的铸模温度必须高于300℃,才有可能满足临床精度要求。
