To inspect the human adult odontometrics by the assistance of 3D cone beam computerized tomography (CBCT) imaging in Saudi, Jordan and Egypt population.
Data of this cross sectional study from 252 subject were analysed by 3D CBCT volumetric data in college of dentistry, Aljouf University, from December 2016 to May 2017. All measurements were done by 3D on demand software. The tooth size from 2nd molar to 2nd molar of maxillary and mandibular arch was measured. Independent test and ANOVA were used to examine the differences between gender and among Arabic population (Saudi, Jordan and Egypt) on the all tooth size.
Comparison between the right and left side odontometrics were significantly dissimilar in 9 out of 14 pairs (p < 0.05). The odontometrics of the 2nd molar to 2nd molar tooth of maxillary and mandibular arch between gender and among Saudi, Jordan and Egypt population were insignificant (p > 0.05).
3D CBCT imaging permits us to measure the tooth size effectively and accurately. Based on results, significant asymmetry was revealed in 9 out of 14 pairs in relation to side disparities. No significant differences in tooth size between gender and among races were found. CBCT can elevate the record keeping problem, human adult odontometrics for the analysis can be obtained directly from the digital image.
借助三维锥形束计算机断层扫描（CBCT）成像技术，对沙特、约旦和埃及人群的成年人类牙齿测量学进行研究。
本横断面研究的数据来自2016年12月至2017年5月在阿尔朱夫大学牙科学院的252名受试者的三维CBCT容积数据。所有测量均使用按需三维软件进行。测量了上颌和下颌牙弓从第二磨牙到第二磨牙的牙齿大小。采用独立样本t检验和方差分析来检验性别之间以及阿拉伯人群（沙特、约旦和埃及）之间在所有牙齿大小上的差异。
14对数据中有9对左右侧牙齿测量学比较存在显著差异（p<0.05）。上颌和下颌牙弓第二磨牙到第二磨牙的牙齿测量学在性别之间以及沙特、约旦和埃及人群之间无显著差异（p>0.05）。
三维CBCT成像使我们能够有效且准确地测量牙齿大小。基于结果，14对数据中有9对在左右侧差异方面显示出显著的不对称性。未发现性别之间以及种族之间在牙齿大小上有显著差异。CBCT可以解决记录保存问题，可直接从数字图像中获取用于分析的成年人类牙齿测量学数据。
