This pilot study evaluated an Index of Orthodontic Treatment Need Learning Package which was developed for use by general dental practitioners. Fifty-seven dentists participated in a randomised controlled trial which involved assessing the need for orthodontic treatment among two representative samples of 16 study casts. All the dentists assessed the first set of study casts without any aids or assistance. During the assessment of the second set of study casts one group of dentists used an IOTN Learning Package in the form of a poster, another group used an IOTN Learning Package in the form of a booklet, and the remaining group acted as a control and did not use any Learning Package. The results reveal that compared with the control dentists, the dentists using the IOTN poster and the IOTN booklet had, respectively, 1.8 and 2.6 fewer errors when assessing aesthetic need and 2.0 and 2.1 fewer errors when assessing dental health need.
这项试点研究评估了一个为普通牙科医生开发的正畸治疗需求指数学习包。57名牙医参与了一项随机对照试验，该试验涉及评估两组各16个研究模型的正畸治疗需求。所有牙医在没有任何辅助工具或帮助的情况下评估第一组研究模型。在评估第二组研究模型时，一组牙医使用海报形式的正畸治疗需求指数学习包，另一组使用小册子形式的正畸治疗需求指数学习包，其余组作为对照组，不使用任何学习包。结果显示，与对照组牙医相比，使用正畸治疗需求指数海报和小册子的牙医在评估美观需求时分别少犯1.8个和2.6个错误，在评估牙齿健康需求时分别少犯2.0个和2.1个错误。
