The objective of this study was to assess the validity of the IOTN-AC in the assessment of aesthetic impairment in bimaxillary protrusion patients.
A cross-sectional study was conducted and involved 110 patients comprising 52 males (47.3%) and 58 females (52.7%) who were accepted for fixed appliance treatment at The University of the West Indies Dental Hospital and provided consent for the use of their records. The mean age was 13.45 years. Participants were asked to complete a questionnaire regarding their reasons for seeking orthodontic treatment and score their self-perceived IOTN-AC. An orthodontist also scored the malocclusion using the IOTN (AC and DHC).
Spearman’s correlation between patient IOTN-AC and orthodontist IOTN-AC was
The IOTN-AC is not a valid tool to determine patient perception of the need for treatment in a bimaxillary protrusion population when scored by either patients or orthodontists.
