Abstract
Malocclusion is an appreciable deviation from ideal occlusion that may be considered as aesthetically or functionally unsatisfactory. Treatment need indices are used to determine the need prior to orthodontic treatment. Index of Treatment Need (IOTN) and Dental Aesthetic Index (DAI) are the most common indices used to determine the severity of malocclusion and treatment need. The aims of this study are to evaluate students’ diagnostic ability in determining orthodontic treatment need using IOTN and DAI, and to determine students’ perception to both indices. This study was carried out on 49 clinical dental students of the Islamic Science University of Malaysia (USIM). They attended a seminar and practical sessions on the IOTN and DAI indices given by orthodontist. All students were asked to score 20 study models using both indices. At the end of assessment, students were asked to answer questionnaires regarding their perceptions towards both indices. The data was analysed using paired t-test, kappa statistic and descriptive analysis. USIM clinical dental students were able to determine the severity of malocclusion using IOTN significantly better (p< 0.05) than DAI. The inter-rater reliability assessment resulted in interclass correlation coefficient of 0.62 for the IOTN and 0.61 for DAI. Questionnaires revealed that students prefer to use IOTN more than DAI in determining severity of malocclusion. Clinical dental students showed better understanding in diagnostic assessment using IOTN than DAI in determining severity of malocclusion.
