Third molar size predictive model (and associated dataset)

This model and its associated dataset is based on computed tomography data from 323 molar regions of a multiethnic group of 99 Western Canadian dental patients. This model was created for the following main purpose: to determine whether third molar (M3) crown size* can be accurately and significantly estimated based upon the crown size* of its adjacent predecessors: the first and the second molars (M1 and M2, respectivelly). Our results showed that the crown size of M1 and M2 are reliable predictors for the crown size of the adjacent M3. * Crown size: refers to the mesiodistal length of the crown.

本模型及其配套数据集基于99名加拿大西部牙科患者组成的多种族群体的323处磨牙区域的计算机断层扫描（computed tomography）数据构建。本模型的核心研发目标为：探究是否可依据相邻前序磨牙——第一磨牙（M1）与第二磨牙（M2）的牙冠尺寸，准确且具有统计学显著性地估算第三磨牙（M3）的牙冠尺寸*。研究结果表明，M1与M2的牙冠尺寸可作为相邻M3牙冠尺寸的可靠预测指标。* 牙冠尺寸：指牙冠的近远中径长度。
