Resumen
Different studies support the anatomical complexity of the root canal system by the presence of multiple foramina, apical deltas, accessory canals and more variations. The purpose of this in vitro study was to identify the internal anatomy of the root canal system of 84 permanent maxillary first molars, determining the number of canals per root and also the type of canals according to the classification of Vertucci and the prevalence of secondary mesio-buccal (MB2) by diafanization process. The palatal root as well the distal root showed only one canal in 100% of cases, whereas in the vestibular root one canal was present in 58.3%, two canals in 38.1% and three canals in 3.6% of the cases. Regarding the prevalence of MB2 it was present in 41.7%. As for the canal type, the most frequent in palatal and distal roots was type I, in 98.8%and 96.4%, respectively, while in the mesio-buccal root type I was the most prevalent in 31.0% of cases, followed by type V in 25.o% and type II in 16.7%
