This systematic review aims to answer the following focus question: "Is there an association between atypical swallowing and malocclusions?".
Appropriate word combinations were chosen and tailored specifically for each of the following electronic databases: EMBASE, Latin American and Caribbean Literature in Health Sciences (LILACS), LIVIVO, PubMed/Medline, Scopus, Web of Science, and gray literature, without any restrictions, up to February 2021. According to the selection criteria, only cross-sectional studies were included. The following inclusion criteria were considered: a sample composed of children, adolescents, and adults; patients clinically diagnosed with atypical swallowing; patients with normal swallowing; and outcome of interest of atypical swallowing in patients with malocclusion. The data consisted of study characteristics, sample characteristics, results, and conclusion of each study. The risk of bias was assessed using the JBI Critical Appraisal Checklist for Analytical Cross-Sectional Studies, and the certainty of evidence was assessed using the GRADE tool.
4,750 articles were identified. After a two-step selection, four studies were included. A higher frequency of distal occlusion, extreme maxillary overhang, and open bite was related to swallowing disorders; most studies pointed to posterior crossbite as a malocclusion more associated with atypical swallowing. All studies had a moderate to high risk of bias, and the certainty of evidence was very low.
The results indicate that atypical swallowing is associated with malocclusions and that posterior crossbite is the main malocclusion found, but only in the young population (3-11 years).

本系统评价旨在回答以下焦点问题：“非典型吞咽与错畸形之间是否存在关联？”。
选择了适当的词组合，并专门针对以下电子数据库进行了定制：EMBASE、拉丁美洲和加勒比健康科学文献（LILACS）、LIVIVO、PubMed/Medline、Scopus、Web of Science 和灰色文献，没有任何限制，截至 2021 年 2 月。根据选择标准，仅纳入了横断面研究。纳入标准如下：样本由儿童、青少年和成人组成；临床诊断为非典型吞咽的患者；吞咽正常的患者；以及错畸形患者非典型吞咽的结果。数据包括研究特征、样本特征、结果和每个研究的结论。使用 JBI 分析性横断面研究批判性评价清单评估偏倚风险，使用 GRADE 工具评估证据确定性。
共确定了 4750 篇文章。经过两步筛选，纳入了 4 项研究。远端咬合、上颌过度突出和开颌的频率较高与吞咽障碍有关；大多数研究指出后牙反颌是与非典型吞咽更相关的错畸形。所有研究均存在中高度偏倚风险，证据确定性非常低。
结果表明，非典型吞咽与错畸形有关，后牙反颌是主要的错畸形，但仅在年轻人群（3-11 岁）中发现。
