The present study evaluates the reliability of the Radio Memory® software (Radio Memory; Belo Horizonte, Brasil.) on classifying lower third molars, analyzing intra- and interexaminer agreement of the results.
An observational, descriptive study of 280 lower third molars was made. The corresponding orthopantomographs were analyzed by two examiners using the Radio Memory® software. The exam was repeated 30 days after the first observation by each examiner. Both intra- and interexaminer agreement were determined using the SPSS v 12.0 software package for Windows (SPSS; Chicago, USA).
Intra- and interexaminer agreement was shown for both the Pell & Gregory and the Winter classifications, p<0.01, with 99% significant correlation between variables in all the cases.
The use of Radio Memory® software for the classification of lower third molars is shown to be a valid alternative to the conventional method (direct evaluation on the orthopantomograph), for both clinical and investigational applications.
本研究旨在评估 Radio Memory® 软件（Radio Memory；巴西贝洛奥里藏特）在分类下颌第三磨牙方面的可靠性，分析结果的观察者内和观察者间一致性。
对 280 颗下颌第三磨牙进行了一项观察性、描述性研究。使用 Radio Memory® 软件对相应的全景片进行了两位检查者的分析。每位检查者在第一次观察后 30 天重复进行检查。使用 Windows 版 SPSS v 12.0 软件包（SPSS；美国芝加哥）确定了观察者内和观察者间的一致性。
在 Pell & Gregory 和 Winter 分类中，均显示出观察者内和观察者间的一致性，p<0.01，所有情况下变量之间均具有 99%的显著相关性。
使用 Radio Memory® 软件对下颌第三磨牙进行分类是对传统方法（直接在全景片上评估）的有效替代，可用于临床和研究应用。
