Abstract :Aim: Nasopalatine canal is one of the important anatomical structures in the anterior maxillary region. The aim of this study was to investigate the changes in nasopalatine canal (NPC) morphology according to dentition status using cone beam computed tomography (CBCT). Material and Methods: CBCT images of a total of 100 patients were analyzed retrospectively. CBCT images were divided into two groups according to the dentition of the anterior maxilla: 50 patients with edentulous anterior maxillary region and 50 patients without tooth loss. After recording age, gender and dentition status of the patients, NPC length, incisive foramen (IF) diameter, stenon foramina (SF) diameter, NPC angle between NPC and palatal plane were measured on the sagittal plane. Results: When relationship between dentition and NPC angle, NPC length, SF and IF diameters were analyzed, no statistically significant difference was found between the variables (p>0.05). When the variables were evaluated according to age and gender, NPC length and NPC angle were found to be significantly higher in the male gender (p<0.05), while the diameter of the incisive foramen increased with age, and this was statistically significant (p<0.05). Conclusion: NPC can show significant anatomical variations in both its morphology and dimensions. A careful preoperative evaluation is necessary to avoid possible complications during dentoalveolar surgery.
