الملخصBackground: The upper permanent canine tooth germ develops close to maxillary sinus (MS) 1 therefore, upper canine displacement and MS pneumatization may have a link. 2 This study aims to evaluate the MS dimensions, volume, and range of anterior and vertical MS pneumatization in bilaterally palatally (PDCs) and buccally displaced maxillary canine (BDCs) compared to normally erupted canine (NDCs) subjects. Methods: Cone-Beam-Computed-Tomography (CBCT) images of 167 patients (131 females/33 males, age averaged 18.88 ± 1.66 years) were included in the study. Maxillary canines were bilaterally displaced palatally in 60 patients, buccally in 57 patients, and normally erupted in 50 subjects. The following variables were measured: anterior, lateral, and vertical distance from canine cusp tip to MS wall, MS volume and dimensions, and MS anterior and inferior pneumatization. The paired sample t-test was applied to detect differences between the right and left sides. Differences between the three groups were assessed using Chi-square and ANOVA one-way analysis tests. Results: More anterior MS pneumatization was detected in maxillary displaced canines compared to NDCs’ subjects. MS was extended to the incisor region in 20%, 10%, and 4%, and to canine region in 10%,12%, and 24.5% in PDCs, BDCs, and NDCs subjects, respectively (X2 = 19.22, p = 0.014). Significant differences between the right and left sides were detected, subsequently, right and left sides values were averaged (Table 1). PDCs subjects had a smaller lateral distance from the canine tip to MS wall compared to BDCs subjects (p < 0.05) and a reduced average vertical position of the canine tip to MS compared to NDCs subjects (P < 0.001). BDCs subjects had a larger vertical distance from canine tip to MS (p < 0.001), an increased MS volume (p < 0.01), and a reduced MS width (p < 0.05). Conclusion: MS showed anterior pneumatization in subjects with maxillary displaced canines. In BDCs’ subjects, MS showed lateral pneumatization. MS width and volume were larger in BDCs subjects compared to PDCs and NDCs subjects.
