en Evalution of the Relation between Maxillary Canine Impaction with Arch Dimensions and Maxillary Sinus Dimensions Using Cone Beam Computed Tomography (CBCT ) تخصصي Special مقالات اصيل Original Article Background: We aimed to evaluate the morphology of maxilla and sinus dimension in subjects with unilaterally and bilaterally impacted canine using cone beam computed tomography (CBCT) records. Methods: CBCT records taken during 2020-2022 of 120 patients were obtained to investigate the relationship between impacted canine and maxilla morphology as well as sinus dimension. The CBCT images were then divided into three control, unilaterally and bilaterally canine impaction groups. Then morphology-related variables (arch circumference and arch length , inter molar width, inter first molar width, palatal depth, anterior posterior of right and left side sinus, and mediolateral dimension of right and left side sinus)  were analyzed and compared between groups. All measurements was measured by Ondeman3D dental software, the unit of measurement was millimeter. Statistical analysis was carried out by SPSS software version 21 using one-way ANOVA and post hoc tests. Results: In patients with canine impaction (compared with control group), there were meaningful differences in arch circumference (P value= 0.004) and arch length (P value= 0.001), inter molar width (P value= 0.001), inter first premolar width (P value= 0.001), mediolateral dimension of right (P value=0.001) and left side (P value= 0.001) sinus of maxilla. Furthermore, Palatal depth and anterior posterior of right and left sinuses were not statistically significant difference between groups. Conclusion: Canine impaction can considerably affect the morphology of maxillary and sinuses dimension. Nevertheless, future studies are needed to determine the exact structural and molecular effects that canine impaction can have on maxillary sinuses and neighboring tissues.   Tooth, Impacted, Maxillary sinus, Cone-Beam Computed Tomography 32 38 http://wjps.ir/browse.php?a_code=A-10-913-2&slc_lang=en&sid=1 Homa Farhadifard 100319475328460015812 100319475328460015812 Yes Dental Implants Research Center, Department of Orthodontics, School of Dentistry, Hamadan University of Medical Sciences, Hamadan, Iran Abbas Shokri 100319475328460015813 100319475328460015813 No Dental Implants Research Center, Department of Oral and Maxillofacial Radiology, School of Dentistry, Hamadan University of Medical Sciences, Hamadan, Iran Maryam Salehzadeh 100319475328460015814 100319475328460015814 No Department of Orthodontics, School of Dentistry, Tabriz University of Medical Sciences, tabriz, Iran.
