Abstract
Background: By further understanding the impact of malocclusion on self-esteem and different domains of Oral Health Related Quality of Life (OHRQoL) such as functional, physical, social and psychological in school children, it will aid in planning a realistic treatment, as expected by patients. Aim: To determine the impact of the severity of malocclusion on self-esteem and OHRQoL among Malay ethnic students. This study also evaluated the relationship of malocclusion severity with self-esteem and OHRQoL. Method: This prospective cross-sectional study was conducted on 252 Malay students aged 13 to 16 years old. Rosenberg self-esteem Scale (RSE scale) and Oral Health Impact Profile14 questionnaires (OHIP-14) were used for assessing the children's self-esteem and OHRQoL respectively. Oral examination was performed by the use of Index of Orthodontic Treatment Need (IOTN) ruler to examine the severity of malocclusion. Pearson correlation coefficient was used to evaluate the relationship between severity of malocclusion, selfesteem, and OHRQoL. Regression analysis was done to determine the effects of the severity of malocclusion on self-esteem and OHRQOL. Result: 139 (55.2%) of participants were male and 113 (44.8%) were female. 133 (52.8%) aged 13 to 14 and 119 (47.2) were 15 to 16 years old. Mean scores and standard deviation of the RSES and OHIP-14 were 33.64 (±3.40) and 9.72 (±8.39) respectively. There was no statistically significant difference in malocclusion severity between male/female and students age group (p>0.05). A weak positive relationship was observed between OHIP-14 and IOTN DHC (r = 0.186; p < 0.01). OHIP-14 was significantly and positively associated with sex, females have higher impact scores than males (B =2.413;p <0.05), indicating the significant association between sex and OHIP-14 score. This association became stronger in multivariate model [B = 2.673; 95% confidence interval (CI) = 0.639-4.707; р < 0.05]. There was а significant association between (IOTN-DHC) and OHIP-14. (B=1.235 p <0.05). Conclusion: Female exhibited more negative impact of malocclusion on their OHRQoL. A weak positive correlation was found between malocclusion and OHRQoL. In the present study the OHRQoL of the students was affected by malocclusion severity. This study provided information that low quality of life was associated with severity of malocclusion.
