Various analytical methods are available regarding mixed dentition; initially Tanaka and Johnston (TJ) space analysis was performed on a North European descent population. It is trust worthiness among various ethnic and racial groups to be predicted. In this analysis, the summation of MM (Maxillary ...
北方汉族人Tanaka-Johnston预测方程研究张海萍首都医科大学口腔医学院正畸科目的:分析北方汉族青少年下颌切牙总宽度与尖牙、双尖牙总宽度之间的相关性,探寻适合目标人群的Tanaka—Johnston预测方程。方法:从就诊于首都医科大学附属口腔医院正畸科的病例中选取记存模型127副。研究下颌切牙总宽度与尖牙、双尖牙总宽度之间的相关性...
北方汉族人Tanaka-Johnston预测方程研究
目的:本研究拟验证Tanaka-Johnston预测方程用于上海地区青少年牙列间隙分析的可行性,并通过测量分析上海地区年轻恒牙列宽度以建立上海地区青少年牙列间隙分析预测方程.方法:按纳入标准选取恒牙超硬石膏模型288副,其中男性132副,女性156副.使用电子数字显示游标卡尺对上,下颌各牙齿牙冠宽度进行测量,测量计算后得到下切牙总宽度...

To compare the prediction of unerupted permanent canine and premolar size of a comparable sample size of southern Chinese population with that of the study of Tanaka and Johnston. Teeth on study casts of an unselected sample from a 12-year-old Hong Kong Oral Health Survey of 12-year-old chi...
Tanaka and Johnston[1]预测方程用于混合牙列间隙分析,通过测量已萌恒下切牙近远中径,预测未萌恒尖牙双尖牙近远中径,以判断混合牙列的拥挤程度,确定治疗方案。由于其简便、准确,在国外正畸临床广为应用。本研究用Tanaka and Johnston方法,建立了适合汉族人群的尖牙、双尖牙近远中径预测方程,为正畸临床提供简捷的诊断...
Tanaka-Johnston equationsIntroduction: It is important to predict mesiodistal crown width of the unerupted permanent canine and premolars in the mixed dentition, which helps to better determine malocclusion and its further development. Methods: In this study, 120 pair of dental study casts, belonged...
aExcept for the maxillary arch in male subjects, Tanaka and Johnston regression equations underestimated the mesiodistal widths of permanent canines and premolars. On the other hand, there were no statistically significant differences between actual mesiodistal widths of canines and premolars and the pre...
