Methodology Cluster analyses were conducted using all data for children ages 0-4 years in aggregate： 1） for all subjects, and 2） for subjects without crowned restored teeth. Each of these two sets of analyses consisted of 8 differently specified cluster analyses as a validation procedure. Results The caries patterns identified from the clustering analysis are： 1） smooth surfaces （other than the maxillary incisor）, 2） maxillary incisor, 3） occlusal surfaces of first molars, and 4） pit and fissure surfaces of second molars. Conclusion The cluster analysis findings were consistent with results produced by multidimensional scaling. These cross-validated patterns may represent resulting disease conditions from different risks or the timing of various risk factor exposures. As such, the patterns may be useful case definitions for caries risk factor investigations in children under 60 months of age.展开更多
目的:采用透明冠结合纤维桩在全麻下修复乳上前牙残冠,探究提高低龄儿童乳上前牙残冠修复保存率的方法。方法:选择笔者科室收治的在全麻下完成乳上前牙残冠治疗的18例患儿(共46颗患牙)为研究对象。所有患儿进行完善的根管治疗后,利用透...目的:采用透明冠结合纤维桩在全麻下修复乳上前牙残冠,探究提高低龄儿童乳上前牙残冠修复保存率的方法。方法:选择笔者科室收治的在全麻下完成乳上前牙残冠治疗的18例患儿(共46颗患牙)为研究对象。所有患儿进行完善的根管治疗后,利用透明冠结合纤维桩修复乳上前牙残冠。根据美国公共卫生署 (United States public health service,USPHS) 改良Ryge评价标准,分析术后成功率。结果:术后1、3、6、12个月治疗成功率分别为97.8%、95.7%、91.3%、84.8%。结论:采用透明冠结合纤维桩修复低龄儿童乳上前牙残冠的成功率高,可临床推广应用。展开更多
