Abstract

INTRODUCTION

This was a cross-sectional study to investigate the agreement between assessments of orthodontic treatment need of the index of complexity, outcome, and need (ICON) and the index of orthodontic treatment need (IOTN).

METHODS

Five hundred two subjects (253 girls, 249 boys; ages, 11-14 years) participated in this study, including a few who were wearing an orthodontic appliance (1 girl, 5 boys). ICON scores and the aesthetic (AC) and dental health components (DHC) of the IOTN were recorded in those not undergoing treatment. The percentages of subjects needing treatment (ICON score >43) and the different complexity components of ICON were compared between the sexes. Observed percentages of agreement and kappa statistics were used to analyze the agreement between the AC and DHC of the IOTN and also the ICON, and the DHC and AC of the IOTN dichotomized into a yes or no categories of orthodontic treatment need.

RESULTS

No sex differences were found between male and female subjects for treatment need (ICON score >43; P >0.05) and treatment complexity (P >0.05). The kappa statistic for diagnostic agreement between the DHC and AC of the IOTN was 0.55 (95% CI, 0.48-0.63). The kappa statistics for diagnostic agreement between the ICON and the AC and the DHC of the IOTN were 0.40 (95% CI, 0.33-0.46) and 0.78 (95% CI, 0.73-0.83), respectively. The observed agreement between the DHC and the AC of the IOTN was 81.8%. The observed agreement between the ICON and AC and DHC of the IOTN were 71.3% and 89.5%, respectively.

CONCLUSIONS

In terms of orthodontic treatment need, there was moderate agreement between the ICON and the AC (IOTN), and between the DHC and the AC. There was good agreement between the ICON and the DHC of the IOTN. The ICON is a good substitute for the DHC of the IOTN.

摘要

简介

本研究为横断面研究，旨在调查复杂性结局与需求指数（ICON）和正畸治疗需求指数（IOTN）的评估之间的一致性。

方法

502 名受试者（女 253 名，男 249 名；年龄 11-14 岁）参与了本研究，其中包括几名佩戴正畸矫治器的受试者（1 名女性，5 名男性）。在未接受治疗的受试者中记录了 ICON 评分以及 IOTN 的美学（AC）和牙齿健康成分（DHC）。比较了男女之间需要治疗的受试者百分比（ICON 评分>43）和 ICON 的不同复杂性成分。使用观察到的一致性百分比和 Kappa 统计来分析 IOTN 的 AC 和 DHC 之间以及 ICON 和 IOTN 的 DHC 和 AC 之间的一致性，将正畸治疗需求的 yes 或 no 类别进行分类。

结果

在治疗需求（ICON 评分>43；P>0.05）和治疗复杂性方面，男女受试者之间没有性别差异（P>0.05）。IOTN 的 DHC 和 AC 之间的诊断一致性的 Kappa 统计值为 0.55（95%CI，0.48-0.63）。ICON 与 IOTN 的 AC 和 DHC 之间的诊断一致性的 Kappa 统计值分别为 0.40（95%CI，0.33-0.46）和 0.78（95%CI，0.73-0.83）。IOTN 的 DHC 和 AC 之间的观察一致性为 81.8%。ICON 与 IOTN 的 AC 和 DHC 之间的观察一致性分别为 71.3%和 89.5%。
