Background Accessory maxillary ostium (AMO) has a major role to play in the aetiology of maxillary sinusitis. Mucosal thickening is one of the key radiographic features of chronic maxillary sinusitis. The aim of this study was to identify the location of the AMOs and investigate the association between Mucosal Thickening [MT] and AMO using Cone Beam Computed Tomography [CBCT]. Methods CBCT scans of 400 maxillary sinuses from the records of 200 patients who seeked various dental treatments at the Thumbay Dental Hospital, Gulf Medical University, Ajman, United Arab Emirates were evaluated. The incidence, anatomical position and maximal length of accessory maxillary ostia (AMO) in the maxillary antrum were reviewed using CBCT by two examiners. The association between MTs and AMOs were also analysed. Results Among the 200 CBCT scans, 131 belonged to male patients and 69 scans belonged to female subjects within the age group of 18–65 years (mean age 41.32 years). AMOs were found in 142 m...

OBJECTIVES. To assess the presence of anatomic variations and pathology of the maxillary sinus using cone beam computed tomography (CBCT) of the maxilla where pre- implant surgery is planned. MATERIAL AND METHODS. This retrospective study evaluates a sample CBCT scans of 34 dental patients (68 sinuses). CBCT is used to assess maxillary sinus mucosa and outflow and prevalence of septa. The mucosal thickening was measured and the sinus outflow was classified as open or obstructed. RESULTS. Mucosal thickening was found in 48.5%, septa in 20.6% and total opacity in 2.9% of the sinuses. Maxillary sinus outflow was blocked in 26.5% of the scans. Strong association between radiological signs of maxillary sinus ostium blockage and thickened mucosa was observed. CONCLUSIONS. Anatomic variations and lesions of the maxillary sinus were common findings in CBCT examinations of the maxilla required for dental preprosthetic planning. Routine CBCT scans, including maxillary sinus ostium are recomme...

Introduction Odontogenic infections are one of the common causes of maxillary sinusitis. With the close proximity of the roots of maxillary posterior teeth to the sinus floor, the infection may spread into the sinus causing sinus mucosal thickening. This study aims to evaluate the association between maxillary posterior teeth periapical pathologies and maxillary sinus mucosal changes using cone-beam computed tomography (CBCT) images. Methods One-hundred six maxillary posterior teeth with periapical lesions were included in this study and were assessed using CBCT images by two maxillofacial radiologists. The proximity of the roots to the sinus floor, the proximity of the top edge of the periapical lesion to the sinus floor, and the sinus mucosal changes associated with the periapical lesions were studied. The size of the periapical lesion was measured and scored using CBCT periapical index. Mucosal thickening more than 2 mm was considered pathological and the type, pattern, and severity of mucosal thickening were assessed. Data were analyzed using chi-squared tests at a level of significance set at pvalue less than 0.05. Results Among the 106 teeth with periapical lesions, 99 teeth (93.4%) revealed the presence of maxillary sinus mucosal thickening. The prevalence of mucosal thickening increased significantly with the presence of cortical bone destruction, the close proximity of the root, and the periapical lesion to the sinus floor. The generalized type of mucosal thickening was more prevalent with larger periapical lesions and a significant increase in the severity of the thickening was observed closer spatial relationship of the root to the sinus floor. Conclusion Periapical pathologies of maxillary posterior teeth often cause sinus mucosal thickening. The early diagnosis and management of these pathologies will be helpful in preventing the spread of infection into the maxillary sinus.
Objectives To evaluate the relationship between proximity of the root apices of healthy maxillary posterior teeth to the maxillary sinus floor (MSF) and mucosal thickening (MT) of the MSF using cone beam computed tomography (CBCT). Methods Eighty-four CBCT images obtained from the patients, aged between 20 and 70 years with healthy and fully dentate maxillary posterior sextants, were included. The anatomical relationship between root apices of maxillary posterior teeth and MSF, was evaluated: (Type 1: no contact, Type 2: at least one root apex in contact, Type 3: at least one root apex protruding into MSF). Besides, MT of the MSF was measured from the thickest region. The patients were categorized into two groups based on the absence (≤ 2 mm) or the presence (2 < mm) of MT. Statistical significance was accepted at p < 0.05. Results Intraexaminer consistency demonstrated an excellent agreement (p < 0.05). The prevalence of Type 1, 2, and 3 proximity were found as 26 (15.5%), 61 (36.3%), and 81 (48.2%); respectively. Overall, 62 (36.9%) maxillary sinuses demonstrated MT (2 < mm, mean: 8.6 ± 7.5 mm). The prevalence and mean values of MT (2 < mm) were not found to be statistically significantly different in terms of sex and proximity types (p > 0.05). Logistic regression analysis results were not found to be statistically significant (p > 0.05). Conclusion The proximity of healthy maxillary posterior teeth to the MSF was not found to be a contributing factor for the MT of the MSF. Further studies with larger samples, taking the other factors causing MT into consideration, are needed.

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 and periodontal status. Thickening >1 mm was considered pathological and was categorized by degree (2 = 1-3 mm; 3 = 3-6 mm; 4 = 6-10 mm; 5 = more than 10 mm). The statistical analysis was performed to determine the association between MT of the sinus and the dental and periodontal status. Results: MT was observed in 102 patients (40.3%; mean=7.01 ± 6.07mm), of which 13.7% were second degree, 25.5% were third degree, 25.5% were fourth degree, and 35.3% were fifth degree. Periodontal disease was seen in 168 patients (66.3%), of whom 110 (65.5%) had mild disease, 44 (26.2%) had moderate disease, and 14 (8.3%) had severe disease. Ninety-seven patients (52.2%) who had MT were 2.84 times more likely to be have periodontal disease, and there was a statistically significant relationship between periodontal disease and sinus MT (P=0.001). Multivariate analysis revealed an odds ratio of 14.39 for MT in the patients with periodontal disease. Bivariate and multivariate statistical analyses; were used for the assessment of dental and periodontal status. Conclusion: A retrospective inspection of CBCT images revealed that the prevalence of maxillary sinus MT was positively associated with periodontal disease, gender, and age. In addition, periodontal disease seems to be the most important parameter influencing mucosal thickness.

Odontogenic infections can directly trigger maxillary sinusitis. CBCT is an excellent choice for precise examination of maxillary sinuses and hard tissues within the oral cavity. The objective of this retrospective and the cross-sectional study was to analyze the influence of odontogenic conditions on the presence and intensity of maxillary sinus mucous membrane thickening using CBCT imaging. Moreover, periodontal bone loss and anatomic relationship between adjacent teeth and maxillary sinuses were assessed to evaluate its possible impact on creating maxillary thickening. The study sample consisted of 200 maxillary sinuses of 100 patients visible on CBCT examination with a field of view of 13 cm × 15 cm. The presented study revealed a significant influence of periapical lesions, inappropriate endodontic treatment, severe caries, and extracted teeth on the presence of increased thickening of maxillary sinus mucous membrane. In addition, an increase in the distance between root apices...
