This study evaluated the pathologic and spatial associations between apical periodontitis of the maxillary premolars/molars and the maxillary sinus mucosal thickening using cone-beam computed tomography (CBCT) scanning. CBCT images of 372 patients with 508 exposed maxillary sinuses were inspected retrospectively. Clinical features such as sex and age of the patients and pathologic findings of the maxillary sinus and adjacent teeth were recorded, graded, and analyzed. Maxillary sinus mucosal thickening was found in 180 (48.4%) patients and 235 (46.2%) sinuses. The prevalence of maxillary sinus mucosal thickening increased dramatically as the severity of apical periodontitis increased (from 41.5% in those without periodontal disease to 100%). However, the nature of the spatial relationship between the maxillary sinus floor and the infected root tips or between the sinus floor and periapical lesions did not appear to have an effect on the prevalence of maxillary sinus mucosal thickenin...

Background. This retrospective study aimed to investigate the effect of various dental and maxillary sinus variables on maxillary sinus mucosal thickness (MT). The variables included periodontal bone loss (PBL), periapical status, dental restorations of posterior maxillary teeth, and the distance from the root apices to the sinus mucosa. Methods. Cone-beam computed tomography (CBCT) images of the maxillary sinuses (n=600) in 300 patients were examined. The sinus MT and the distance of the roots from maxillary sinuses were measured. Apical lesions of the roots, PBL, and situations of adjacent teeth were recorded. The relationships between these conditions and MT and characterization of MT were evaluated. The Kruskal–Wallis H test was used to compare groups due to the non-normal distribution of the data. The relationship between categorical variables was analyzed using chi-squared test. Results. There was a significant correlation between maxillary sinus MT and periapical lesions, PBL...

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.

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...

Background: The detailed relationship between apical periodontitis and maxillary sinus mucosal thickening is still unknown. The aim of this study was to evaluate the association between maxillary posterior teeth periapical odontogenic lesions and maxillary sinus mucosal (MSM) thickening by using volumetric 3D CT analysis. Methods: A total of 83 subjects with apical periodontitis around maxillary posterior teeth and maxillary sinus mucosal thickening were selected. 3D models of maxillary sinus mucosa and apical lesions were reconstructed from CT, and their volume, mean diameter were calculated. Results: Mean MSM thickening was 8.81 ± 12.59 mm with an average volume of 5092.58 ± 7435.38 mm3. Men had higher MSM thickening than women. Mean diameter of apical lesion was 5.94 ± 2.68 mm; average volume was 200.5 ± 197.29 mm3. Mean distance between MSM and apical lesion was 1.83 ± 2.07 mm. Mucosal volume was the highest in the S1 and D1 configuration and the lowest in R3. Reducing the dista...

Introduction: Odontogenic infections affects the maxillary sinus mucosa. Cone Beam Computed Tomography (CBCT) is helpful in diagnosis of maxillary sinusitis of odontogenic origin. This cross-sectional study was planned with the aim to assess maxillary sinus changes associated with odontogenic infection by evaluating CBCT images. Material and methods: In cross-sectional analytical study, total 213 patients (404 sinuses) were evaluated on CBCT after thorough clinical examination of the individuals and taking into consideration the history of rhino or allergic rhinitis. Based upon CBCT images and clinical examination, patients were divided into, study group (odontogenic infection) and control group (no associated odontogenic infection). Effect of the size of periapical lesion, spatial relationship of lesion to the sinus floor and periodontal bone loss on maxillary sinus changes were evaluated. Results: Mucosal changes found in 200 sinuses (49.5%), mucosal thickening being the most prevalent and more commonly associated with odontogenic infections (p = 0.004). A significantly increased risk of mucosal thickening was observed with severe periodontal bone loss (p = 0.008). Size and spatial relationship of lesion to the maxillary sinus had no impact on the prevalence of mucosal thickening (p = 0.6, p = 0.4 respectively). Periodontal bone loss was 2.2 more likely to be associated with mucosal thickening than periapical or combined lesion. Conclusions: Most prevalent sinus change was mucosal thickening. Periodontal bone loss was significantly associated with mucosal thickening. CBCT is an appropriate method for sinus evaluation.

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...

The aim of the present study is to explore the correlation between maxillary sinus diseases and inflammatory processes in the maxillary teeth in patients eligible for implant rehabilitation with a preoperative examination using cone-beam computed tomography (CBCT).Materials and methods:282 CBCT images of the maxilla and 530 images of the maxillary sinus were analyzed. Only teeth with chronic periodontitis and with no other pathological process were recruited in the target group.The distance between the sinus floor and theperiodontal pocketdepth(PPD) and the thickness of theSchneiderian membranearound each tooth was recorded.Results: The mean thickness of the maxillary sinus mucosawas 7.74 mm, reaching its highest value at 26 mm (as seen in 2 patients with chronic periodontitis). The mean distance between the periodontal involvement and the maxillary sinus floor for the affected teeth was 5.53 mm. The distance varied between 0 mm and 13 mm.Conclusions: This retrospective study showed that the thickness of the sinus membrane is directly related to the inflammatory processes of periodontium of the teeth adjacent to the sinus.
