目的：本研究的目的是比较多生牙患者和对照组之间的牙齿大小测量。方法：多生牙组包括56名受试者（21名女性和35名男性）和对照组40名受试者（20名女性和20名男性）。使用图像分析系统从颊面和咬合面两个角度对牙模上所有可用的恒牙进行成像和测量。近远中，颊舌或咬合牙龈的尺寸，面积和周长进行了测量，从每个view.Results：多生牙患者往往有较大的牙齿尺寸测量几乎所有的变量比对照组。上、下切牙的近远中径和下第一前磨牙的颊舌径存在显著性差异（p < 0.05）。结论：多生牙是一种复杂的牙齿异常，其病因复杂，遗传和环境因素都很重要。有一些证据表明，局部效应与邻近多余物部位的牙齿尺寸差异更大。(c)2004 Elsevier Ltd.保留所有权利。
Objective: The aim of this study was to compare tooth size measurements between patients with supernumerary teeth and a control group.Method: The supernumerary group consisted of 56 subjects (21 females and 35 mates) and the control group of 40 subjects (20 females and 20 mates). All available permanent teeth on the dental casts were imaged and measured from both buccal and occlusal views using an image analysis system. Mesio-distal, bucco-lingual or occluso-gingival dimensions, area and perimeter were measured from each view.Results: Supernumerary tooth patients tended to have larger tooth size measurements for almost all variables than controls. Significant differences (p < 0.05) were found for the mesio-distal dimension of the upper and lower incisors and the bucco-lingual dimensions of the Lower first premolars.Conclusions: The results are compatible with supernumerary teeth being a complex dental anomaly with a multifactorial aetiology in which both genetic and environmental factors are important. There is some evidence of a local effect with greater differences in tooth dimension adjacent to the site of the supernumeraries. (c) 2004 Elsevier Ltd. All rights reserved.
