assessment of the self-perception of dental appearance, its comparison with orthodontist’s assessment and demand for treatment in eastern nepalese patients

Aims. The aim of this study was to assess the self-perception of dental appearance among Eastern Nepalese patients using aesthetic component (AC) of the index of orthodontic treatment need (IOTN) and to compare it with that of an orthodontist’s assessment using the same scale and determine whether gender, area of residence, and level of education influence subject’s self-perception and orthodontist’s ratings. Methods. A total of 252 subjects (equal number of male and female) were conveniently selected. The average ages of subjects were 22.33±2.114 years. The level of subject’s perception and orthodontist’s assessment was analyzed by nonparametric Chi square test. Kappa coefficient was done to verify its agreement. The Spearman’s correlation test was used to check the association of educational level and age. Mann-Whitney test was used to check the associations of sex and areas of residence. Results. The demand for treatment was significantly associated with the perception of the subject and orthodontist’s assessment. However, age, gender, and educational level were statistically insignificant in influencing subject perception and orthodontist’s assessment. Conclusion. Patient’s self-perception should be given equal importance while planning orthodontic treatment.
