杭州市2～6岁儿童乳牙龋病的流行病学调查分析和乳牙预成冠的力学实验研究OACSTPCD
Epidemiological Investigation and Mechanical Experiment of Deciduous Tooth Precrown in 2-6 Year Old Children in Hangzhou City
目的:了解杭州市2～6岁儿童龋齿的牙面分布规律,比较树脂、氧化锆、玻璃陶瓷乳牙预成冠的抗压缩破坏力值.方法:抽取杭州口腔医院城西院区儿童口腔科就诊的1 000名2～6岁儿童进行口腔检查并记录,分析患龋差异.将树脂、氧化锆、玻璃陶瓷乳牙预成冠分别用树脂粘接剂粘接在下颌第二乳磨牙的树脂模型上.在万能材料试验机上进行抗压缩强度测试,记录试件抗压缩破坏力值.采用SPSS 24.0统计分析软件对数据进行统计分析.结果:右下第二乳磨牙患龋风险最高,左侧第二乳…查看全部>>
