The purpose of this study was to determine the relationship between the upper third molar and the maxillary sinus as evaluated in Cone Beam CT scans, Lima 2022. The study was observational, cross-sectional, and retrospective. A total of 90 CT scans were used, and observation along with a data collection sheet was the instrument employed. For the relationship between the upper third molar and the maxillary sinus, the Jung and Cho classification was used. Additionally, the Winter and Modified Archer classifications were applied. It was found that 41.7% of the patients had the sinus floor above the roots (Class 1), while 44.4% (Class 2), 12.5% (Class 3), 0.7% (Class 4), and 0.7% had the sinus floor extending to the neck of the tooth. The largest number of patients (26.4%) were women who had the sinus floor above the roots (Class 1). The largest number of patients (27.1%) were between 18 and 29 years old, and the sinus floor touched the ends of the root (Class 2). On the right side, 24.3% of patients had the sinus floor above the roots (Class 1). 63.9% of the patients presented a vertical spatial location of the upper third molar according to the Winter classification, and 68.8% had class A impaction according to the Archer classification. The study concludes that the most frequent relationship between the maxillary sinus and the upper third molar is when the sinus floor is above the roots.
