abstract

introdouction: cone-beam computed tomography (cbct) scanning is a technological innovation developed in recent years with potential use in oral surgery and many other dental procedures. the aim of this study is to determine the maxillary sinus mucosal thickening in the maxillary premolar-molar area using the cbct technique. materials and methods: in this retrospective study, a total of 105 cases (49 females and 56 males) that had 186 exposed maxillary sinuses were included. the age range of the cases was 24–58 years old. periapical infections of maxillary molars and mucosal thickness changes were detected and recorded by two specialists in a radiologist and a periodontist. results: mucosal thickening in either one or both maxillary sinuses was found in the periapical area of 14 second premolars (13.3%), 48 first molars (45.7%), 39 second molars (37.1%), and 4 third molars (3.8%), with mucosal thickenings >1.8 mm. the mean maxillary sinus mucosal thickening in cases with pa radiolucency was 1.7 mm, and in patients without pa radiolucency, the mean was 2.1 mm (p = 0.01). mucosal thickening due to pulpal infections of untreated teeth was seen in 39 (37.1%) cases, and mucosal thickening due to inadequate previous root canal therapy was seen in 66 (62.9%) patients. conclusion: cbct is a helpful method for detecting periapical lesions which affect the maxillary sinus and is recommended in maxillary surgical procedures.

Evaluation of the Association of Sinus Mucosal Thickening with Dental and Periodontal Status Using Cone Beam Computed Tomographic Imaging

Introdouction: Cone Beam Computed Tomography (CBCT) is a relatively new three-dimensional imaging technology, which has been widely used in dental and maxillofacial imaging. Materials and methods: CBCT scans of 506 maxillary sinuses of 253 individuals (39.9% male and 60.1% female) were evaluated retrospectively for assessing the relationship between sinus mucosal thickening (MT) and dental a...

بررسی ارتباط بین ضخامت مخاط سینوس ماگزیلاری و با استفاده از periodontal bone loss Cone beam computed tomography

Introduction: Odontogenic infections are one of the common cause of maxillary sinusitis. This study aimed to evaluate the relationship between the teeth with periapical lesions or periodontal disease and sinus mucosal thickening using cone-beam computed tomography(CBCT). Methods: This was a retrospective and cross-sectional study. CBCT scans of 97 patients(188 sinuses) were evaluated retrospec...

Evaluation of prevalence and pattern of maxillary sinus mucosal thickening in cone beam computed tomography of dental implant candidates in Shiraz, Iran

BACKGROUND AND AIM: This study aimed to assess maxillary sinus floor membrane thickness and ostium patency (OP) in patients undergoing cone beam computed tomography (CBCT) evaluation for implant placement in the posterior maxilla. Mucosal thickening (MT) could be cause of post-operative complications in implant procedures; awareness of this incidence could help proper detection and further succ...
