This article is aimed at assessing the orthodontic treatment outcome in an accredited graduate orthodontic clinic in the United States, using the original Peer Assessment Rating (PAR) Index. A sample of 100 pre- and posttreatment study models was randomly selected from the clinic model storage. One investigator assessed all the components of the PAR Index. Descriptive statistics and Scheffe test were used to analyze the data. The mean weighted PAR point reduction was 22.11, and mean percentage reduction was 86.20. "Greatly improved" conditions were seen in 50% of patients while 47% accounted for the "improved category." Only 3% belonged to the "worse or no different" group. Statistically significant differences were observed between the three improvement groups for weighted pre- and posttreatment PAR scores, reduction, and percentage reduction. The results indicated an excellent improvement of the patients, with patients being treated to a high standard and a great proportion of patients with a clear need for treatment.
本文旨在使用原始的同行评估评分（PAR）指数，评估美国一家获得认证的研究生正畸诊所的正畸治疗效果。从诊所模型库中随机抽取了100个治疗前和治疗后的研究模型样本。由一名研究人员评估PAR指数的所有组成部分。使用描述性统计和谢费检验来分析数据。PAR加权平均分降低了22.11，平均降低百分比为86.20。50%的患者状况“大幅改善”，47%属于“改善类别”。只有3%属于“更差或无差异”组。在三个改善组之间，治疗前和治疗后的PAR加权评分、降低值和降低百分比存在统计学上的显著差异。结果表明患者有显著改善，患者接受了高标准治疗，且很大一部分患者明显需要治疗。
