This paper reports the results of a study of the reliability of a modified version of the Index of Orthodontic Treatment Need (IOTN) for use in oral health surveys. Twelve non-specialist dental examiners were trained in the use of the Modified IOTN using a standardised teaching protocol lasting approximately 1.5 hours. Following a school-based calibration exercise it was found that nearly all the examiners achieved either good or excellent agreement (mean Kappa=0.74). The average sensitivity and specificity scores were 0.90 and 0.84, respectively. The Modified IOTN appears to overcome the training and reliability problems that often accompany the use of orthodontic indices by non-specialists in oral health surveys.
本文报告了一项关于改良版正畸治疗需求指数（IOTN）在口腔健康调查中可靠性的研究结果。12名非专科牙科检查人员通过持续约1.5小时的标准化教学方案接受了改良IOTN使用方法的培训。在一次基于学校的校准练习后发现，几乎所有检查人员都达到了良好或优秀的一致性（平均卡帕值=0.74）。平均敏感度和特异度得分分别为0.90和0.84。改良IOTN似乎克服了口腔健康调查中非专科人员使用正畸指数时经常伴随的培训和可靠性问题。
