Abstract
Aim: To assess the proximity between the roots of maxillary molars and Maxillary Sinus Floor ‘MSF’ using CBCT in a sample from the Egyptian population.
Materials and Methods: Eighty seven CBCT scans of adult Egyptians (29 males and 58 females) involving 135 maxillary 1st molars, 168 maxillary 2nd molars and 107 maxillary 3rd molars, were collected from patients’ data base of Planmeca Promax 3D Mid CBCT machine available at the Department of Oral &Maxillofacial Radiology, Faculty of Dentistry, Cairo University. The vertical relation between MSF and examined teeth roots was assessed on cross sectional CBCT images based on Jung classification 2009
Results: In all mesio-buccal “MB’, disto-buccal ‘DB’& palatal ‘P’ roots of the examined teeth, the 1st molars showed the highest prevalence of class (0) in the 3 roots, while the 2nd molars showed the highest prevalence of class (3) among both MB & DB roots, and the highest prevalence of class (2) among P roots, finally 3rd molars showed the highest prevalence of class (1) among DB roots, and the highest prevalence of class (3) among P roots. There was a significant inverse correlation between age and vertical relationship classes of only the first maxillary molars roots. Males showed higher prevalence of Class (2) and Class (3) while females showed higher prevalence of Class (0) and Class (1) in the 3rd molars.
Conclusion: In the investigated Egyptian subjects, maxillary 1st molars’ roots are the least close to the MSF compared to the other molars roots, while buccal roots of maxillary 2nd molars are highly anticipated for MSF invagination. The lower the age is, the closer are the maxillary 1st molar roots to the MSF, and males’ maxillary 3rd molars are more frequently approximating MSF than females.
