ABSTRACT
Dentists must understand the role of maxillary sinus diseases and their relationship to teeth and supportingstructures. The most maxillary sinus disease is Odontogenic maxillary sinusitis. Cone-beam computedtomography (CBCT) is the imaging choice in dental practice to evaluate maxillary sinuses and maxillofacialstructures. Maxillary sinuses carry a variation of mucosal thickening. If the mucosa of maxillary sinuses exceedsmore than 2 mm, it indicates the possibility of infection in the maxillary sinuses. More than 50% of patients visitingthe dental practice have thickening of lining mucosa more than 2 mm. Limitation for CBCT includes difficulty todifferentiate between soft-tissue attenuation. This review aims to emphasize the role of CBCT in the detection ofmaxillary sinus diseases in dental practice. In conclusion, the CBCT examination is the best and convenientimaging tool in the dental practice that can identify the presence of pathology in maxillary sinus before surgeryor post-operative complication and follow-up. This literature review was done to emphasize the demand for CBCTas an imaging investigation tool. This imaging modality is increased nowadays due to its accurate diagnosis ofdental disease and routine evaluation of alveolar bone for implant placement and sinus lift surgery.
