BACKGROUND: There is a scarcity of data concerning the prevalence and pattern of malocclusion and orthodontic treatment needs in Syrian refugee. In this study, extra and intra-oral features of malocclusion and the dental health component of the Index of Orthodontic Treatment Need (IOTN) were reported. METHODS: Examination of 606 Syrian children/adolescents refugees attending Zaatari clinic was carried out (males = 280, females = 326, mean age = 11.84 ± 2.1 years). Subjects not within the age limit, with a history of orthodontic treatment, or with craniofacial anomalies were excluded. Both extra and intra-oral features of malocclusion were assessed. Intra-oral features included inter- and intra-arch occlusal characteristics: crowding, spacing, crossbite, overjet, overbite, molar and canine relationship, incisor relationship, and centerline shift. In addition, the dental health component (DHC) of the Index of Orthodontic Treatment Need (IOTN) was recorded. Gender and age variations in malocclusion characteristics and IOTN grading were tested using chi-square and nonparametric tests respectively (P < 0.05). RESULTS: The prevalence of malocclusion was 83.8% (52.6% class I, 24.2% class II, 7% class III). The most common features of malocclusion were crowding (71.1%) followed by centerline shift (52.1%), increased overjet (36.1%), high vertical proportions (34%) and deep overbite (31.2%); there were significant gender and age differences for a number of occlusal traits. The prevalence of moderate to severe need for orthodontic treatment was 67.7%. CONCLUSIONS: This study provides baseline data on the prevalence of malocclusion in Syrian refugee children/adolescents in Zaatari camp where data concerning oral health of this population are lacking. The prevalence of orthodontic treatment need was high warranting the need for a comprehensive interceptive orthodontic program to prevent increasing oral health problems in the future. This high burden of oral diseases has a negative financial impact on the hosting country which can be reduced through public health interventions and implementing community-based dental healthcare for this underprivileged population.
背景：有关叙利亚难民错颌畸形和正畸治疗需求的流行率和模式的数据稀缺。本研究报告了错颌畸形的口腔内外特征和正畸治疗需求指数（IOTN）的口腔健康组成部分。
方法：对在扎塔里诊所就诊的 606 名叙利亚儿童/青少年难民（男性 280 名，女性 326 名，平均年龄 11.84 ± 2.1 岁）进行了检查。排除年龄不在限制范围内、有正畸治疗史或有颅面畸形的患者。评估了错颌畸形的口腔内外特征。口腔内特征包括：牙弓内和牙弓间的咬合特征：拥挤、间隙、反颌、覆颌、深覆颌、磨牙和尖牙关系、切牙关系和中线移位。此外，还记录了正畸治疗需求指数（IOTN）的口腔健康组成部分（DHC）。使用卡方和非参数检验分别测试性别和年龄对错颌畸形特征和 IOTN 分级的影响（P < 0.05）。
结果：错颌畸形的患病率为 83.8%（I 类 52.6%，II 类 24.2%，III 类 7%）。最常见的错颌畸形特征是拥挤（71.1%），其次是中线移位（52.1%）、覆颌增加（36.1%）、垂直比例高（34%）和深覆颌（31.2%）；许多咬合特征存在显著的性别和年龄差异。需要中度至重度正畸治疗的患病率为 67.7%。
结论：本研究提供了在扎塔里难民营中叙利亚难民儿童/青少年错颌畸形流行率的基线数据，而该人群的口腔健康数据缺乏。正畸治疗需求的患病率很高，需要进行全面的阻断性正畸治疗计划，以防止未来口腔健康问题的增加。这种高负担的口腔疾病对收容国产生了负面影响，通过公共卫生干预措施和为这一弱势群体实施社区口腔保健，可以减轻这种影响。
