To determine whether malocclusion is associated with oral-health-related quality of life (OHRQoL) in New Zealand adolescents.
Data from two cross-sectional epidemiological studies of adolescents in Taranaki and Otago were used. Each participant completed a self-administered questionnaire and underwent a clinical examination. Information collected included sociodemographic characteristics (sex, ethnicity and household deprivation), and clinical measures (caries and malocclusion, the latter measured with the Dental Aesthetic Index, or DAI). OHRQoL was measured using the validated 16-item impact short-form Child Perceptions Questionnaire (CPQ11-14). Linear regression was used to model the CPQ11-14 score.
783 adolescents (52.6% male) took part. One-fifth had a handicapping malocclusion and one-third had a minor malocclusion or none. The overall mean DMFS was 2.3 (SD, 3.8), with slightly more than 50% being caries-free. With the exception of the oral symptoms domain, females presented with higher mean CPQ11-14 and domain scores, while Mãori had lower scores. There was a distinct gradient in mean CPQ11-14 and domain scores across the categories of malocclusion severity, whereby those in the 'handicapping' category of the DAI had the highest CPQ11-14 score. Linear regression modeling of the CPQ11-14 score showed that, after controlling for DMFS and socio-demographic characteristics, malocclusion category and being female were positively associated with higher CPQ11-14 scores.
A severe malocclusion appears to have a negative impact on the OHRQoL of New Zealand adolescents.
确定错牙合畸形是否与新西兰青少年的口腔健康相关生活质量（OHRQoL）有关。
使用了来自塔拉纳基和奥塔哥青少年的两项横断面流行病学研究的数据。每位参与者都完成了一份自我管理的问卷，并接受了临床检查。收集的信息包括社会人口学特征（性别、种族和家庭贫困状况）以及临床指标（龋齿和错牙合畸形，后者用牙科美学指数或DAI测量）。使用经过验证的16项儿童感知问卷简表（CPQ11 - 14）测量OHRQoL。采用线性回归对CPQ11 - 14得分进行建模。
783名青少年（52.6%为男性）参与了研究。五分之一的青少年有妨碍性错牙合畸形，三分之一有轻度错牙合畸形或无错牙合畸形。总体平均龋失补牙面数（DMFS）为2.3（标准差，3.8），超过50%的青少年无龋齿。除口腔症状领域外，女性的CPQ11 - 14及各领域平均得分更高，而毛利人的得分较低。在错牙合畸形严重程度类别中，CPQ11 - 14及各领域平均得分存在明显梯度，DAI“妨碍性”类别的青少年CPQ11 - 14得分最高。对CPQ11 - 14得分进行的线性回归建模显示，在控制了DMFS和社会人口学特征后，错牙合畸形类别和女性与较高的CPQ11 - 14得分呈正相关。
严重的错牙合畸形似乎对新西兰青少年的OHRQoL有负面影响。
