Many of the failures in the endodontic treatments are by the lack of knowledge of the operator of the anatomical characteristics of the teeth to treat; being this a determining factor. Many studies have been made on the external and internal anatomy in maxillary premolars, finding discrepancies in the results. The purpose of this study was to determine the variations of the external and internal root anatomical characteristics of maxillary premolars; As well as, overall length of vestibular and palatal maxillay premolars; determine the number of roots, direction of this, disposition of the roots canals and presence of apical deltas. A total of 40 CT Cone beam were selected, where it was evident first with intact premolars second, to be observed and analyzed by Romexis program, which we find data and findings as follows: the average length vestibular in the first was 20.41 % and 19.61% average length palatal both men and women; and the second 20.48% 18.87% vestibular and palatal women; They further found that maxillary premolars presented: a root (75% and 100% first second, both males and females); higher prevalence of straight and curved root apical (and the second 54.2% and 31.3% 43.8% and 37.5% in the first) was found; and unique ducts (43.7% and 37.5% the first and the second 87.5% and 79.2%) in most cases. Secondary lines were also found (25% the first and the second 20.8%), interconductos (31.2% and 12.5% the first second); and apical deltas (51% in the first and second in women 50% in males).
