Abstract
Background: Indices of orthodontics are systematic evaluations that measure the extent of deviation (malocclusion) from a standard. Aim: To investigate if there is a change in the patients perception of orthodontic malocclusion in this decade compared with the previous one using the Index of Complexity, Outcome and Need (ICON). Materials and Methods: A total of 400 orthodontic study models were selected randomly. The study was designed to include two groups; the first group thus included 200 study models for patients who sought treatment before the year 2000, specifically between 1990 and 1999, and the second group included 200 study models for patients who sought treatment after the year 2000, specifically between 2000 and 2009. The study models were examined and occlusal traits were scored. Five occlusal traits were assessed: Index of Orthodontic Treatment Need (IOTN) aesthetic components, Overall upper arch crowding/spacing, Cross bite, Anterior vertical relationship (incisor overbite/openbite), Buccal segment antero-posterior relationship (right and left sides added together). Results: the results showed significant difference the treatment need assessment (P=.000), the complexity distribution (P=.000), occlusal trait distribution (P=.000), and aesthetic score distribution (P=.000), between the two groups. Conclusions: the predominant occlusal traits seen in patients sought orthodontic  treatment before the year 2000 were different than occlusal traits seen in patients sought orthodontic treatment after the year 2000. However, over the years, antero-posterior jaw relationship and dental crowding remained the main concerns for orthodontic patients
