Abstract

Background: Maxillary sinus pneumatization is a physiological process that can adversely affect bone availability for further dental rehabilitation. If a relation between the thickness of the mandibular cortex and maxillary sinus pneumatization is proven, future bone availability can be deducted. Material and methods: In this cross-sectional study, 85 panoramic radiographs were evaluated. All patients were between 19 and 70, had at least lost a second premolar, first molar, or second molar on one side of the maxilla, and had these teeth on the other side. Four lines were digitally drawn on the radiographs to determine the superior and inferior borders of the sinus on both sides. The amount of inferior sinus border progression was deducted using the digitally-measured lines' ratios. The following tests were done using IBM SPSS ver. 24: Pearson's correlation coefficient test, Tukey's dual comparison posthoc test, One-way ANOVA test, and the independent T-test (p = 0.05). Results: There was a negative correlation between the inferior mandibular cortex's thickness and the maxillary sinus's pneumatization (p < 0.001). Also, there was a significant difference between maxilla sinus pneumatization in the second premolar, first, and second molar areas based on the inferior mandibular cortex's thickness (p = 0.009). Conclusions: Based on the present study, there is a significant relationship between the thickness of the inferior mandibular cortex and maxillary sinus pneumatization, especially for women and patients above 40 years old. © 2023 THE AUTHORS
