Association between the dimensions of the maxillary sinus membrane and molar periodontal status: A retrospective CBCT study

Abstract

Background: The information of the association between residual alveolar bone height and mucosal thickening is sparse. This study aimed to explore the effect of maxillary molar periodontal status on sinus mucosal thickening using cone-beam computed tomography (CBCT). Methods: One hundred ninety-four CBCT images were evaluated for the following parameters: age, sex, alveolar bone loss, maximum mucosal thickness (maxMT), minimum residual alveolar bone height (minRABH), and vertical infrabony pockets. The presence of mucosal thickening (maxMT > 2 mm) of the maxillary sinus was recorded. The parameters that could influence the dimensions of the maxillary sinus membrane were assessed. The data were analyzed using logistic regression, and multivariate linear regression with the significant level at = 0.05. Results: Mucosal thickening was present in 32% of the analyzed CBCT images and increased in frequency as the periodontal status of the corresponding molar progressed from mild (2.6%) to moderate (14.9%) to severe (75.5%). Mucosal thickness was significantly increased in cases of moderate (odds ratio = 5.73, P < 0.05) and severe (odds ratio = 82.06, P < 0.001) alveolar bone loss. Multivariate linear regression revealed that alveolar bone loss and minRABH had a statistically significant influence on maxMT (P < 0.05). Conclusions: Alveolar bone loss and minRABH were significantly associated with mucosal thickening of the maxillary sinus.

Association between Periodontal Status and&nbsp;Degree of&nbsp;Maxillary Sinus Mucosal&nbsp;Thickening: a&nbsp;Retrospective&nbsp;CBCT&nbsp;Study

“…And this is also the factors that in uences the degree of maxMT in our study. The attachment loss of vertical infrobony pockets as well as root furcation lesions in our study did not correlate with the degree of the maxMT, similar to the results of Zhang et al [21]. The results shows that the amount of ABL is a hallmark of the severity of periodontitis and is one of the ultimate outcomes of periodontitis [23].…”

“…The relevant factors associated with maxMT are mainly the amount of ABL, vertical infrobony pockets, minRABH and the classi cation of root furcation lesions in previous studies [5]. And some studies have analyzed only the minRABH and the amount of ABL associated with maxMT [19][20][21][22]. And this is also the factors that in uences the degree of maxMT in our study.…”

Assessment of the relationship between the maxillary sinus and the canine root tip using cone beam computed tomography

“…Evaluation of the relationship between the maxillary sinus and the dentition is essential for dental procedures, such as implant or apical surgeries and orthodontic treatments [ 5 , 6 ]. Moreover, assessing these anatomical structures is also important since they provide a pathway for infection to spread from the periodontal or peri-apical lesions into maxillary sinuses, which can cause maxillary sinusitis [ 7 – 9 ].…”

Assessment of the Relationship between the Maxillary Sinus and the Canine Root tip using Cone Beam Computed Tomography

“…Two-or three-dimensional (2D or 3D) imaging has been used for evaluating the paranasal sinuses. However, in cases with accompanying signs and symptoms regarding sinuses or need for a thorough examination of the sinuses prior to surgeries, 3D imagings are the modalities of choice [9]. In this regard, CBCT provides accurate and distortion-free images of the craniofacial bones with lower absorbed radiation dose compared with multi-slice computed tomography [17][18][19].…”

“…The relationship between the maxillary sinus and dentition is important for dental procedures, particularly implant or apical surgeries and orthodontic treatment [5,6]. Moreover, the close proximity between these structures leads to infectious spread from periodontal or peri-apical lesions to the maxillary sinus which may cause maxillary sinusitis [7][8][9].…”
