This research was deductive, quantitative, basic type with an observational, descriptive, and cross-sectional design. A data collection form was used, and the sample consisted of 144 tomographies, analyzing 254 upper first molars, which were selected according to inclusion criteria. The data were processed in SPSS version 25. Results showed that of the 254 upper first molars, 104 (41%) had the MB2 canal and 150 pieces (59%) did not. Regarding the side, 39.5% was on the right and 42.4% on the left. As for gender, 34.8% in females and 51.6% in males had the MB2 canal. Regarding age, 40.7% for those under 20 years, 55.9% for those between 20-40 years, and 64.9% for those over 40 years.
