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 ...
Johnston for northern Chinese were generated and the accuracy for different prediction equations was evaluated.Results The coefficients of correlation between combined diameters of canines and premolars and lower incisors were 0.71 and 0.77 in male,and 0.50 and 0.56 in female.The equations from other ...
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...

the results obtained with the application of the tanaka-johnston formulas were compared with the real values through statistical tests. after the analysis of the results, it was observed that the correlation between the estimated values and the real values was greater for females than it was for ...
REGRESSION analysisPEDIATRIC dentistryBackground: Lower incisors are the first teeth to erupt, their sizes are reliable and little changes occur on the lower arch during mixed dentition. These teeth can be used to predict the size of remaining unerupted teeth. Tanaka Johnston's an...
A Chinese mixed dentition analysis based on the Tanaka and Johnston method was constructed with linear regression equations for prediction of the mesiodistal widths of unerupted canines and premolars. Sexual dimorphism was evident between southern Chinese males and females in incisors, canines, and ...
Mixed dentition analysisTanaka-Johnston methodIndonesia childrenThe Tanaka-Johnston method was used to predict the size of the un erupted canine and premolar teeth in the maxilla and mandible. However, the accuracy of the Tanaka-Johnston equation is still questionable when used in different ethnic...
Conclusion: Tanaka and Johnston analysis and BUA are valuable in mixed dentition analysis, offering insights into space availability for orthodontic treatment planning. BUA serves as a reliable substitute for TJA when fully erupted permanent incisors are absent, emphasizing the...
Conclusion: The Tanaka-Johnston analysis was not precise enough to be used for the North Karnataka population in its original form, so new regression equations were developed.Bangi, Sayeeda LaequeKondody, Rony T.Sana, SafiyaFatima, AsmaHussain, Arshad...
