VANNUCCI, Marcello Gaieta et al. Comparative study of variability of position of impacted third molars patients in teens and young adults. Stomatos []. 2010, 16, 31, pp. 04-13. ISSN 1519-4442.

The aim of this study was establish the prevalence of the position of the third molar. This objective was accomplished using panoramic x-ray. Our variables in concern were the most frequent position and the distribution between genders of this tooth. These x-rays were selected by the following inclusion criteria: existence of the second molar in the hemi-arcade and presence of the non-erupted third molar in the hemi-arcade. We used 100 x-rays, which 42% showed all third molars, 15% showed three, 31% showed two, 9% showed one and 3% showed no third molars. As a result, we found that in all third molars, the most frequent position was the mesio-angular in both genders. We also found that the most frequent position of non-erupted third molar, in both genders, was a mesio-angular, followed by the positions vertical, disto-angular and horizontal.
