The purpose of this study was to evaluate orthodontic treatment outcomes using the American Board of Orthodontics and the Peer Assessment Rating occlusal indices and to determine the affects of treatment variables on ABO and PAR values. Treatment outcomes of 97 consecutively treated pre- and post-treatment study models were compared using ABO and PAR indices. ABO and PAR values were found to present similar interpretations of treatment outcomes for cases under examination. The initial malocclusion of the Class II and extraction groups was twice as severe and took approximately 4 and 6 months, respectively, longer to treat than the Class I and non-extraction groups, but the quality of treatment outcomes for both groups was comparable. There were no gender differences in treatment outcomes except females took slightly longer (approximately 3 months) to complete orthodontic treatment.The collected data was then transferred into the Statistical Package for Social Sciences (SPSS 10.0, Chicago, IL) for ... to the University of Southern California, Health Sciences Campus, Institutional Review Board (IRB) for review and approval.
