Assessment of proximity of the maxillary premolars roots to the maxillary sinus floor in a sample of Egyptian population using CBCT: An observational cross-sectional study

Assessment of Relationship between Maxillary Sinus Floor and Maxillary Posterior Teeth Root Tips Position in a Sample of Egyptian Population using CBCT: An Observational Cross-Sectional Study

“…Our results were also similar to those of Morsy et al, 2022 [22] who conducted their study to assess the relationship between maxillary premolar roots and maxillary sinus floor in an Egyptian population. Morsy et al, 2022 [22] were assessing the relationship between the maxillary premolar roots and the MSF based on a classification proposed by Kilic et al, 2010 and concluded that the highest prevalence among maxillary first premolars (single-, double-, and triple-rooted) exhibited"No relation"to the MSF whereas type 3 sinus relation (roots below the MSF) recorded the second position followed by type 2 (roots contacting the MSF) and finally type 1 (roots penetrating MSF) that was observed in only one single-rooted upper first premolar. Regarding the maxillary second premolars, type 2 sinus relation showed the highest prevalence among the singleand double-rooted second premolars followed by type 3.…”

“…Moreover, complications resulting from the introduction of endodontic instruments, intracanal medicaments, root filling material, extraction or endo-surgery procedures of roots closely related to the sinus may cause iatrogenic perforation of the MSF and formation of oroantral fistula and sinus membrane thickening. [10,[22][23][24] As far as we know, and based upon a meticulous and thorough systematic search in different databases, no studies were found assessing these outcomes collectively in maxillary premolars and molars in an Egyptian population. Hence, our study was thought to assess the relationship of maxillary sinus and posterior teeth root tips position in a sample of Egyptian population aiming to improve the preoperative treatment planning and to avoid complications.…”

“…CBCT images were analyzed in corrected axial, coronal and sagittal planes to detect the anatomic relation between maxillary sinus floor and tips of maxillary multi-rooted and one rooted posterior teeth, the distance between maxillary sinus floor and root tips of posterior teeth as recommended by Morsy et al, 2022; [22] Aksoy & Orhan, 2019; [28] Anter et al, 2019; [29] Razumova et al, 2019; [19] Asthana et al, 2015; [30] Goller-Bulut et al, 2015; [31] Mahnaz Sheikhi, 2013. [26] This relation was evaluated in the examined scans by using the measuring tools available in the viewer software.…”
