Objective: Cone beam computed tomography (CBCT) may be recommended as a dose-sparing technique and 3D imaging that provides the clinician more details for examining the maxillary sinus and its relation to the root apices of upper posterior teeth, as compared with standard medical computed tomography.
Methods: A total of (340) CBCT images were examined, images were analyzed by using (Galileos Viewer Software Version 1.9, Dentsply). The distance was measured from the molar and premolar teeth; the closest tooth to the sinus was considered for both sides
using the software measuring tool.
Results: A total of 340 CBCTs were examined. One hundred and forty-seven CBCTs were included that matched the criteria. After
examination of the CBCTs, the most common relation between the roots of the upper posterior teeth with the maxillary sinus was Type
2: the apices of the upper posterior teeth touching the sinus floor. The result shows no statistical difference between the age groups (p
value = 0.135); also, the relationship between sex and the relation of the teeth with the maxillary sinus was not significant (p value =
0.075).
Conclusions: The most common relation between the apices of maxillary posterior teeth and the maxillary sinus was close contact.
We also concluded that the use of CBCT is essential in diagnosing the type of relation, especially during procedures where oro-antral
communication and trauma to the maxillary sinus is possible.
