Abstract：
In mixed dentition analysis, estimation of the mesiodistal width of unerupted permanent canines and premolars is essential for successful diagnosis and treatment planning. The present study aimed to develop a simple linear equation to predict permanent tooth sizes from mixed dentition analysis for Taiwanese people.
The sample comprised 200 dental casts, derived from Taiwanese patients (100 males and 100 females; age, 12-35 years). Mesial distal tooth widths were measured in dental casts with a digital caliper. A student\'s t-test was conducted to detect tooth size correlations with gender-specific differences, as well as intra-arch counterparts. Standard linear regression was conducted to develop a simple equation representing predictions of canine-premolar relationships.
All teeth were not significantly different between the left and right sides, regardless of gender and upper or lower arches. In terms of types of teeth, males had larger tooth dimensions in both arches than females. New regression equations for estimating the dimensions of the unerupted canines and premolars in the Taiwanese population were developed.
Using a sample of Taiwanese people, new models derived for females and males separately were developed, which should provide highly accurate predictions for unerupted canines and premolars in the Taiwanese population.

摘要：
在混合牙列分析中，估计未萌出的永久性犬齿和前磨牙的中远侧宽度对于成功的诊断和治疗计划至关重要。本研究旨在开发一个简单的线性方程，以从台湾人的混合牙列分析中预测恒牙大小。
样品包括200个牙模，来自台湾患者(100名男性和100名女性；年龄，12-35岁）。用数字卡尺在牙科铸模中测量中远侧牙齿宽度。进行学生t检验以检测牙齿大小与性别特异性差异的相关性，以及拱门内的同行。进行标准线性回归以建立代表犬-前磨牙关系预测的简单方程。
所有牙齿在左右两侧之间没有显着差异，不分性别和上下拱门。就牙齿的类型而言，男性在两个牙弓中的牙齿尺寸均大于女性。建立了新的回归方程，用于估计台湾人口中未喷发的犬齿和前磨牙的尺寸。
使用台湾人的样本，分别为女性和男性开发了新的模型，这应该为台湾人口中未爆发的犬齿和前磨牙提供高度准确的预测。
