Association between Maxillary Posterior Teeth Periapical Odontogenic Lesions and Maxillary Sinus Mucosal Thickening: A 3D Volumetric Computed Tomography Analysis

Abstract

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 distance between apical lesion and MSM by each millimetre, the volume of MSM increases by 759.99 mm3. Conclusions: Volumetric CT analysis is a circumstantial method to evaluate the association between maxillary posterior teeth apical periodontitis and MSM thickening. This relationship is not related to the size of the apical lesion but depends on their anatomical position and the distance from the maxillary sinus mucosa.

Prevalence and pattern of proximity of maxillary posterior teeth to maxillary sinus with mucosal thickening: A cone beam computed tomography based retrospective study

“…In agreement with observations from Sakir and Ercalik Yalcinkaya,[ 8 ] we could not establish any evidence of the relationship between gender or age and the occurrence of pathological mucosal thickening. Many studies[ 3 17 18 ] have found that membrane thickening was associated with factors such as age and gender. A higher prevalence rate of sinus membrane thickening was found in males and older age groups (>50 years old) which is in contrast to our findings.…”

Association between Cone-Beam Computed Tomography and Histological and Immunohistochemical Features in Periapical Lesions Correlated with Thickened Maxillary Sinus Mucosa

“…In our study, we used CBCT imaging in evaluating the preoperative periapical lesions of the maxillary teeth associated with varying degrees of the maxillary mucosa inflammation as an aid in determining the optimum surgical technique for removing the causative dental unit with as little as possible osseous tissue sacrifice and to avoid further sinus complications. Other studies have also stated its undeniable utility in pinpointing the possible etiological dental factor and evaluating the association between periapical lesions of maxillary teeth and the degree of involvement of the maxillary sinus [ 29 , 30 ].…”
