    Introduction: The maxillary sinus (MS) is a structure of great interest due to its proximity to the posterior superior dental structures (1). Knowing the distance between these structures is essential when performing pre-surgical planning (2), especially in case of the second molar due to its proximity to the maxillary sinus floor (MSF) (3–7). Objectives: Determine the distance between the apices of the second molar and the maxillary sinus floor using cone beam computed tomography. Methodology: Computed tomography scans were collected from a radiological center in Cuenca (January 2019 - September 2020). Using the Sydexis 4 software version 4.3, the apico-sinus distance was measured in a coronal cut section. The data collection was carried out using a template and the results were analyzed in the IBM SPSS program. Results: The average value of the apico-sinus distance was 0.45mm, 1.36mm and 2.36mm for the mesiobuccal, distobuccal and palatal roots on the right side. On the left side the values were 0.16mm, 0.66mm and 1.12mm respectively. In both cases the mesiobuccal root was the closest to the MSF. Conclusions: The mesiobuccal root of the second molar has the closest relationship with the MSF. Regarding the age group, the shortest distance is observed in group 3 (right side), and group 2 (left side). According to the sex, the average value is similar in the two groups.
