Usually, morphological parameters of the teeth are recorded to help assess the indication for orthodontic treatment. It is assumed that significant deviations from average values compromise the quality of life. The aim of this study is to analyse the impact of overbite and overjet on oral health-related quality of life (OHRQoL) of children and adolescents.
A total of 748 subjects, aged 9.5-15.5 years, participated in the LIFE child project of the University of Leipzig, where they underwent a general medical and dental examination. Overbite and overjet were measured, and aberrations of the OHRQoL were recorded by the probands themselves, who completed the German version of the Child Perceptions Questionnaire (CPQ-G11-14). The OHRQoL is divided into four domains ("oral symptoms", "functional limitations", "emotional well-being" and "social well-being") and is analysed by means of a CPQ score depending on age, gender, socioeconomic status and orthodontic treatment.
On average, the participants listed 10.5 (±13.1) problem issues on a CPQ scale ranging from 0 to 140. Subjects with current orthodontic treatment had a CPQ score about 2.5 (±2.4) higher than those without treatment. The aberrations were mainly observed in the domains "oral symptoms" and "functional limitations". Multiple linear regression showed that deviations of the overbite had only little influence on the OHRQoL, but deviations of an overjet-especially of >6 mm increased the CPQ summary score about 6 points.
Children and adolescents with overjet deviations of >6 mm in comparison to the norm are associated with significant limitations of the OHRQoL. However, overbite deviations have only little influence.
通常，记录牙齿的形态参数有助于评估正畸治疗的适应症。人们认为，与平均值的显著偏差会影响生活质量。本研究的目的是分析覆合和覆盖对儿童和青少年口腔健康相关生活质量（OHRQoL）的影响。
共有748名年龄在9.5至15.5岁之间的受试者参与了莱比锡大学的LIFE儿童项目，他们接受了全面的医学和牙科检查。测量了覆合和覆盖，并由受试者自己记录OHRQoL的异常情况，他们完成了德文版的儿童感知问卷（CPQ-G11-14）。OHRQoL分为四个领域（“口腔症状”、“功能限制”、“情绪健康”和“社会健康”），并根据年龄、性别、社会经济地位和正畸治疗情况通过CPQ评分进行分析。
平均而言，参与者在CPQ量表（范围为0至140）上列出了10.5（±13.1）个问题。目前正在接受正畸治疗的受试者的CPQ评分比未接受治疗的受试者高约2.5（±2.4）分。异常主要出现在“口腔症状”和“功能限制”领域。多元线性回归显示，覆合偏差对OHRQoL的影响很小，但覆盖偏差——尤其是大于6毫米的覆盖偏差使CPQ总分增加了约6分。
与正常情况相比，覆盖偏差大于6毫米的儿童和青少年与OHRQoL的显著限制有关。然而，覆合偏差的影响很小。
