Abstract

Objective: To assess the impact of malocclusion on the quality of life. Materials and Methods: This cross-sectional study involved 150 subjects attending the Primary Care Unit with no history of orthodontic treatment. The Dental Aesthetic Index (DAI) with 10 occlusal characteristics were measured on study models. Oral health-related quality of life (OHRQoL) was assessed with the Malaysian version of the Oral Health Impact Profile questionnaire (OHIP-14). The Spearman rank-order correlation coefficient was used to evaluate the relationship between the malocclusion and quality of life. Results: Significantly weak correlations (r =.176) were found between the DAI and the OHRQoL. Females and the younger age group (12-19 years) tended to score higher on the OHIP-14 than their counterparts. For males, domain 3 (psychological discomfort; r =.462), domain 4 (physical disability; r =.312), domain 7 (handicap; r =.309), and overall score (r =.289) were weak correlates but significant to the DAI compared with females. The older age group showed a significant weak correlation in domain 3 (psychological discomfort; r =.268) and domain 7 (handicap; r =.238), whereas the younger age group showed no correlation with any domain. Conclusions: The DAI score does not predict the effect of malocclusion on the OHRQoL.
