To evaluate the use and knowledge of the index of orthodontic treatment need (IOTN) by general dental practitioners (GDPs) working within Scotland.
Scottish general dental services (SGDS).
Questionnaires were posted to randomly selected dentists (n=356) working within the SGDS for self-completion and return.
Use of IOTN.Knowledge of IOTN Participants were asked to match 12 malocclusions to the correct IOTN category. Kappa statistics evaluated agreement to a gold standard.
The overall response rate was 64%. Sixty-one percent of respondents did not use IOTN. The most common reason for using the index was to assess treatment eligibility (40.2%). The main reason for non-use was that it was only considered suitable for secondary dental care (27%). Over half (56%) of respondents had received IOTN training at undergraduate level. Knowledge of the index was found to be low--the mean level of agreement was k=0.42 (fair). 10.5% of respondents scored k≥0.61(substantial). The factors most likely to contribute to both use and knowledge of IOTN were having a postgraduate qualification and carrying out orthodontic treatment in practice.
Overall use and knowledge of IOTN among GDPs in Scotland appears to still be low. More resources need to be directed towards improving both undergraduate and postgraduate orthodontic training with the focus on IOTN in particular.
评估在苏格兰工作的普通牙科医生（GDPs）对正畸治疗需求指数（IOTN）的使用情况和了解程度。
苏格兰普通牙科服务（SGDS）。
向随机抽取的在SGDS工作的牙医（n = 356）发放问卷，由他们自行填写并返还。
IOTN的使用情况。IOTN的了解程度 要求参与者将12种错颌畸形与正确的IOTN类别进行匹配。kappa统计量评估与金标准的一致性。
总体回复率为64%。61%的受访者未使用IOTN。使用该指数最常见的原因是评估治疗资格（40.2%）。不使用的主要原因是认为它仅适用于二级牙科保健（27%）。超过一半（56%）的受访者在本科阶段接受过IOTN培训。发现对该指数的了解程度较低——平均一致性水平为k = 0.42（一般）。10.5%的受访者得分k≥0.61（较好）。最有可能促进IOTN使用和了解的因素是拥有研究生学历以及在实践中开展正畸治疗。
苏格兰GDPs对IOTN的总体使用情况和了解程度似乎仍然较低。需要投入更多资源来改进本科和研究生阶段的正畸培训，尤其要以IOTN为重点。
