There is currently no representative information for central Germany on the prevalence of dental malalignments and jaw discrepancies in permanent dentition. The aim of this study was to describe the extent of tooth and jaw malformations in a representative adult population according to conventional orthodontic indices.
Three dimensionally (3D)-oriented study casts were measured from a representative sample of adults from the Halle and Leipzig urban areas consisting of 102 men and 143 women aged between 18 and 39 years, yielding a total of 245 volunteers. The index values we determined were the Index of Orthodontic Treatment Need (IOTN), the German Orthodontic Indication Groups (OIG) and the Occlusal Index (OI). The descriptive evaluation of the data and group comparisons (U test, chi(2) test) were performed with SPSS® 13.0.
More than half of the adults we examined were assessed as needing treatment according to the IOTN (61.6%), the German OIG (59.6%) and the OI (58.4%; intermediate severity = 5.92). We observed no significant differences in age or gender.
This is the first time that the prevalence of orthodontic findings has been documented for the central German area in a cohort representative of the population. Our results reveal a great need for therapy. As the classifications describe different patient groups, the individual need for treatment is inadequately documented.
目前德国中部地区缺乏关于恒牙列牙齿排列不齐和颌骨差异患病率的代表性信息。本研究旨在根据传统正畸指数描述代表性成年人群中牙齿和颌骨畸形的程度。
对来自哈雷和莱比锡市区的102名男性和143名女性、年龄在18至39岁之间的成年代表性样本的三维（3D）定向研究模型进行测量，共有245名志愿者。我们确定的指数值为正畸治疗需求指数（IOTN）、德国正畸指征组（OIG）和咬合指数（OI）。使用SPSS® 13.0对数据进行描述性评估和组间比较（U检验、卡方检验）。
根据IOTN（61.6%）、德国OIG（59.6%）和OI（58.4%；中度严重程度=5.92），超过一半接受检查的成年人被评估为需要治疗。我们未观察到年龄或性别方面的显著差异。
这是首次在德国中部地区具有人群代表性的队列中记录正畸检查结果的患病率。我们的结果显示治疗需求很大。由于这些分类描述的是不同患者群体，个体治疗需求记录不足。
