The aim of this article is to establish a comprehensive nation-wide prevalence of malocclusion traits on the sagittal, vertical, and transverse planes of space in Saudi Arabia.
A systematic search was conducted in three databases (Medline via PubMed, Embase, and Web of Science) and complemented with a manual search of Google Scholar and the reference list of included studies. Original studies of Saudi Arabian healthy individuals at any age were included. The quality and the risk of bias of the included studies were assessed using the Joanna Briggs Institute's appraisal tool. The data about the selected malocclusion traits on the sagittal, vertical, and transverse planes of space were extracted and pooled.
Out of 7163 identified titles, 11 studies were finally included. The risk of bias was high in two studies, moderate in eight studies, and low in one study. The studied age groups were from early childhood to late adulthood, with a total sample size of 19,169 participants. The majority of the studies recruited their sample from school/public sources, whereas the remaining three studies recruited their sample from dental (non-orthodontic) clinics.
Within the limitations of this study, pooled prevalence of Angle's Class I molar relation in Saudi Arabia was similar to other populations but Angle's Class II and Class III molar relations were lower and higher, respectively. These differences could be attributed to population-related differences in craniofacial morphology. Teeth crowding, teeth spacing, and midline shift, along with increased overjet and overbite, were among the most common malocclusion traits occurring in Saudi Arabia.
本文旨在确定沙特阿拉伯人群矢状向、垂直向和横向错（牙合）特征在全国范围内的综合患病率。
在三个数据库（通过PubMed检索的Medline、Embase和Web of Science）中进行系统检索，并辅以对谷歌学术的手动检索以及纳入研究的参考文献列表检索。纳入沙特阿拉伯任何年龄健康个体的原始研究。使用乔安娜·布里格斯研究所的评估工具对纳入研究的质量和偏倚风险进行评估。提取并汇总有关矢状向、垂直向和横向错（牙合）特征的选定数据。
在7163条识别出的标题中，最终纳入11项研究。两项研究的偏倚风险高，八项研究的偏倚风险中等，一项研究的偏倚风险低。研究的年龄组从幼儿期到成年晚期，总样本量为19169名参与者。大多数研究从学校/公共来源招募样本，其余三项研究从牙科（非正畸）诊所招募样本。
在本研究的局限性范围内，沙特阿拉伯人群安氏I类磨牙关系的合并患病率与其他人群相似，但安氏II类和III类磨牙关系的患病率分别较低和较高。这些差异可能归因于颅面形态在人群中的差异。牙齿拥挤、牙间隙和中线偏移，以及覆盖和覆（牙合）增加，是沙特阿拉伯最常见的错（牙合）特征。
