Role of Cone-Beam Computed Tomography in the Detection of Maxillary Sinus Disease

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.

The Employment of CBCT in Assessing Bone Loss around Dental Implants in Patients Receiving Mandibular Implant Supported over dentures

The aim of this study is to evaluate bone loss around implants after delivery of implant supported over dentures using CBCT.This study was performed to evaluate Postoperative bone level around mandibular dental implants using cone beamcomputed tomography (CBCT). The study was conducted on 10 completely edentulous patients that were rehabilitated bycomplete overdentures Patients retained mandibular overdentures by two implants installed in the canine region andretained locator attachments. Standard clinical and laboratory techniques were followed for implant insertion and dentureconstruction for all patients. The implants were divided in two groups. Implants bearing locator attachment with blue nyloninsert (Group I) and implants bearing locator attachment with transparent nylon insert (Group II). The twenty insertedimplants were left undisturbed for three months to achieve osseointegration. The mesial, distal, buccal and lingual bonelevel around the dental implants was evaluated, using the CBCT i-CAT scan with Blue sky Plan® software. Bone level wasobtained at six and twelve months after loading. The CBCT measurements of bone level revealed that there was bone lossaround all aspects of the inserted twenty dental implants
