OBJECTIVES: To determine whether malocclusion is associated with oral-health-related quality of life (OHRQoL) in New Zealand adolescents. METHODS: 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. RESULTS: 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. CONCLUSION: A severe malocclusion appears to have a negative impact on the OHRQoL of New Zealand adolescents.
