Morphological analysis with Cone Beam Computed Tomography of the maxillary sinus in maxillary displaced canine subjects

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