Abstract

Aim: To evaluate any relationship between ICON, IOTN and PAR. To establish whether or not ICON could replace these indices as a measure of orthodontic treatment complexity, outcome and need.

Method: The study models of 55 consecutively treated cases were examined and PAR, IOTN and ICON recorded.

Results: The study showed significant correlations between IOTN and ICON with respect to need and PAR and ICON with respect to outcome.

Conclusion: It appears that ICON does reflect UK opinion and the current study provides some evidence that ICON may effectively replace PAR and IOTN as a means of determining need and outcome.
