RESUMO
Introduction The Index of Orthodontic Treatment Need (IOTN) defines who receives treatment on the NHS. The British Orthodontic Society developed the 'Easy IOTN' app to help the dental team use IOTN more effectively.Aim This study aims to investigate the quality of the 'Easy IOTN' app and any alternative mobile apps developed to aid a dentist's ability to use IOTN.Materials and methods The App Store and Google Play were searched to identify available apps which provide an educational resource for IOTN. Any app identified was assessed using the Mobile App Rating Scale (MARS) and the Royal College of Physicians' health informatics unit checklist. The 'Easy IOTN' app continuous professional development (CPD) section was assessed for accuracy using a focus group.Results Only the 'Easy IOTN' app was identified. It has a mean MARS score of 3.6. Significant inaccuracies were found within the CPD component of the 'Easy IOTN' app.Discussion A mean MARS score of 3.6 is deemed average and is comparable to the quality of other orthodontic apps which exist. Errors contained within the CPD component could confuse users and have a negative impact on IOTN skill development.Conclusions The educational component of the 'Easy IOTN' app is of an acceptable standard, but the CPD section is flawed.
