ABSTRACT
<p><b>OBJECTIVE</b>To assess the outcome of orthodontic treatment with upper jaw or upper and lower jaw extraction for Class II division 1 malocclusion using the peer assessment rating (PAR) index.</p><p><b>METHODS</b>28 patients with Class II division 1 were extracted two first premolars or second premolars of upper jaw, and 24 patients were extracted four premolars of upper and lower jaw N. The PAR was applied on pre-and post-orthodontic treatment dental casts for the fifty-two cases.</p><p><b>RESULTS</b>The upper and lower jaw extraction groups had significantly higher initial PAR scores and the weighted PAR total scores (P<0.05). Although significantly different before treatment, both groups were not statistically different after treatment (P>0.05).</p><p><b>CONCLUSION</b>The upper and lower jaw extraction cases showed more severe dental displacement. Both treatment can acquire successful results.</p>
