Objectives: 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.Study Design: 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).Results: 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.Conclusions: 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.
