| Aim: This research was conducted to assess relationship between maxillary sinus floor and maxillary posterior root tips position in a Sample of Egyptian Population using CBCT. Materials and methods: This cross-sectional study evaluated 144 maxillary premolars and 144 maxillary molars from 41 CBCT scans of 19 male and 22 female patients according to certain eligibility criteria. Image analysis was performed on axial, corrected coronal and sagittal images using Planmeca Romexis® Viewer software. The vertical relationship between maxillary sinuses and maxillary premolars was assessed according to Razumova et al., 2019 classification, while the vertical relationship between maxillary sinuses and maxillary molars was assessed according to Kwak et al., 2004 classification. Inter and intra observer agreement were done using Kappa statistics. Results: Most common vertical relationship between all maxillary premolars and maxillary sinus was Type I while most common vertical relationship for all maxillary molars was Type II. The largest distance was found in first premolars' buccal roots while the smallest distance was found in second molars' mesio-buccal roots. There was a significant inverse correlation between age and vertical relationship classes of only 2nd molar roots. Conclusion:Type I vertical relationship was the most common relationship between all maxillary premolars and MSF while Type II vertical relationship was the most common relationship for all maxillary molars. The largest distance was found in first premolars’ buccal roots while the smallest distance was found in second molars’ mesio-buccal roots. The lower the age is the closer are the maxillary 2nd molar roots to the MSF. | ||||
