    The objective of this study was to determine the pneumatization of the maxillary sinus in partially edentulous posterosuperior patients evaluated through panoramic radiographs. Methodology: The population consisted of 172 panoramic radiographs, and the sample obtained using the finite population formula was 120, which allowed for results to be obtained using Chi-square and Pearson's Correlation. The following conclusions were drawn: In partially edentulous patients in the upper posterior sector, there is a higher percentage of grade 4 pneumatization, 42.9%. The most common number of missing teeth in partial edentulism is 5 teeth (33.3%), followed by 4 teeth (26.7%) and 3 teeth (25.8%). A higher degree of pneumatization is associated with the loss of 4 and 5 teeth in the majority of radiographs evaluated, with 44.4% to 50%. A statistical relationship was found (p<0.05). The degree of pneumatization is higher in females. A moderate positive and significant correlation (R=0.29, p=0.001) was found between the degree of pneumatization and the number of missing posterosuperior teeth. The hypothesis (H) was tested and confirmed: There is a direct relationship between maxillary sinus pneumatization and partially edentulous posterosuperior evaluated in panoramic radiographs. The null hypothesis (0) was rejected.
