      Background: The aim of the study was to determine the association between Association of Pell and Gregory classification with the Ezoddini classification in panoramic radiographs of patients attended in the UPC clinic during 2012 – 2014. Material and Methods: A descriptive, transversal and retrospective observational study was conducted. 499 panoramic radiographs of patients attended in the UPC clinic during 2012 and 2014 were evaluated. As inclusion criteria was considered patients older than 20 years with the two lower third molars. Panoramic radiographs with distortion and radiographs with the third molars in Nolla stage 0-9 were excluded. To determine the relation of the roots of the third molars used the Ezoddini classification and to determinate the position of the third molars Pell & Gregory was used. Results: The results were that the relationship was more frequent in the root canal with 42.5 % (212) to the relation of third molars with the inferior alveolar nerve, followed by the absence of contact 32.9 % (164). The age group was the 20 to 30 years and in greater proportion in the ratio of the root canal with 34.1 % (170). For the association of Pell and Gregory classification of with the Ezoddini classification, class IA is associated with a greater proportion of the absence of contact in 19.2 % (96). Conclusions: If there is an association between the position of the third molar as rated by Pell and Gregory relationship with the roots of the lower third molars with the mandibular canal as rated by Ezoddini .
