ABSTRACT

Objective:To analyze some clinical factors influencing the treatment outcomes by Peer assessment rating(PAR).Meth-ods80 cases underwent othordontic therapy were included.The clinical data and treatment effects were analyzed by PAR,the behav-ioral and psychological evaluation of the subjects was collected and analyzed by statistics.Results:Improvement and great improvement were achieved in 42.5% and 56.3% of the patients.There was no significant difference in different groups of gender,bone-facial con-tour classification and tooth extraction,but there was a significant difference in different groups of Angle classification in terms of pre-treatment PAR and reduction of PAR.There was a linear regression between pre-treatment PAR and reduction of PAR and percentage reduction of PAR,respectively.PAR showed more decrease in the patients of Angle class III classification,than in those with Class II and Class I.Conclusion:PAR is less influenced by gender,bone-facial contour,classification and tooth extraction.PAR evaluation shows that the more severe initial Angle malocclusion the patients have,the more significant improvement they may finally obtain.
