BACKGROUND
The orthodontic diagnosis and treatment planning are the fundamental goals during the mixed dentition period. Numerous methods have been proposed till date such as Nance method, Moyer's method, Staley-Kerber and Tanaka-Johnston's method, and Bernabé and Flores-Mir method.
AIM
The aim of the study is to determine the mesiodistal widths of the lower permanent canines and premolars from Tanaka-Johnston, Moyers, and Bernabé E and Flores-Mir C mixed dentition analysis and to determine the correlation coefficients and the new prediction equation for Sri Ganganagar population.
SETTING AND DESIGN
A total of 3572 children were clinically examined from the contemporary population of Sri Ganganagar city and Outpatient Department of Pediatric and Preventive Dentistry in Sri Ganganagar, Rajasthan. A total of 150 individuals were randomly selected for the study based on the inclusion and exclusion criteria and were designated as "study samples.
MATERIALS AND METHODS
A total of 150 children aged 11-16 years of Sri Ganganagar city were randomly selected. The mesiodistal width of permanent incisors, canines, premolars, and molars was measured with the help of digital vernier caliper with an accuracy of ±0.01 mm. The measurements of canines and premolars were summed up and compared with those derived from Tanaka and Johnston equations, Moyers probability tables, and Bernabé and Flores-Mir equations.
STATISTICAL ANALYSIS
The data obtained were subjected to statistical analysis using IBM SPSS Statistics Windows version "20.0" using Student's -test, Pearson correlation coefficient, and Kruskal-Wallis test.
RESULTS
All the three methods overestimated the actual sum of permanent canine and premolars in both the arches in our population. The correlation coefficients and the new regression equations were derived for both maxilla and mandible in males and females for Sri Ganganagar population.
CONCLUSION
The predicted values obtained from all the three methods overestimated the actual values.
背景
正畸诊断和治疗计划是混合牙列期的基本目标。迄今为止，已经提出了许多方法，如南斯法、莫耶斯法、斯特利 - 克伯法和田中 - 约翰斯顿法，以及贝尔纳贝和弗洛雷斯 - 米尔法。
目的
本研究的目的是通过田中 - 约翰斯顿、莫耶斯以及贝尔纳贝E和弗洛雷斯 - 米尔C混合牙列分析确定下颌恒牙尖牙和前磨牙的近远中宽度，并确定斯里甘加纳格尔人群的相关系数和新的预测方程。
设置与设计
从斯里甘加纳格尔市的当代人群以及拉贾斯坦邦斯里甘加纳格尔的儿科和预防牙科门诊部对总共3572名儿童进行了临床检查。根据纳入和排除标准，随机选择了150名个体作为研究对象，并将其指定为“研究样本”。
材料与方法
从斯里甘加纳格尔市随机选择了150名年龄在11 - 16岁的儿童。借助精度为±0.01毫米的数字游标卡尺测量恒牙切牙、尖牙、前磨牙和磨牙的近远中宽度。将尖牙和前磨牙的测量值相加，并与田中 - 约翰斯顿方程、莫耶斯概率表以及贝尔纳贝和弗洛雷斯 - 米尔方程得出的值进行比较。
统计分析
使用IBM SPSS Statistics Windows版本“20.0”对获得的数据进行统计分析，采用学生t检验、皮尔逊相关系数和克鲁斯卡尔 - 沃利斯检验。
结果
在我们的人群中，所有三种方法都高估了两个牙弓中恒牙尖牙和前磨牙的实际总和。得出了斯里甘加纳格尔人群男性和女性上颌骨和下颌骨的相关系数和新的回归方程。
结论
从所有三种方法获得的预测值都高估了实际值。
