Abstract

Introduction: Maxillary sinus varies greatly in shape, size, and position between different individuals and in different sides of the same individual. CBCT scan is very important in evaluating maxillary sinus characteristics including the relation between maxillary teeth and the sinus. It has many advantages including decreased scanning time and better resolution.

Material and Method: This retrospective study included 100 Patients (45 females, 55 males) with 480 maxillary molars who were referred to Dental Radiology clinic in Baghdad, during the period from December 2020 to July 2021 for CBCTs. 60 patients with 360 teeth were assessed bilaterally and 40 Patients with 120 teeth were assessed unilaterally to determine the vertical relationship between their roots apices and maxillary sinus (MS) floor; using The Trans axial images from a panoramic view of CBCTs according to the classification of Kwak., et al.

Result: We found that 168(35%) of teeth in this study were in class (V) relationship to the floor of maxillary sinus, followed by class (I); 139 (28.95%) teeth, class (II); 129 (26.88%), class (IV); 29 (6.04%) and class (III); 15 (3.13%) respectively. Class (V) relationship was the most frequently seen with 1st and 2nd molars 81(50.63%), 62 (38.75%) respectively. While a class (I) was most commonly observed relation with the 3rd maxillary molars. The relationship between maxillary molars to MS floor were significant (P = 0.000), also it was significant according to age group and gender. Non-significant association were found between left and right side for the 1st, 2nd and 3rd molars in their relationships to the MS floor.

Conclusion: Most of the maxillary molars especially maxillary 1st and 2nd molars are in close proximity to the maxillary sinus floor while maxillary 3rd molars showed safer relation with sinus. There were significant association in the relation of maxillary molars to the sinus floor and also according to the age groups and gender of patients, while the relation was non-significant between right and left side of the maxilla.
