Background: The potential consequences of contact between the implant and the vascular and nervous systems in the nasopalatine canal (NPK), the most prominent anatomical structure in the premaxilla, may result in the failure of osseointegration and damage to the nerves in this region. The objective of this study was to evaluate the morphology and morphometric features of NPC using cone beam computed tomography (CBCT) images and to examine the relationship between these features and demographic variables. Methods: CBCT images of a total of 293 patients aged between 18 and 74 years with a mean age of 40.15 years were analyzed in axial, coronal and sagittal planes. The number of NPCs in the axial plane, anatomical variation of NPCs in the coronal plane, shape variation and morphometric measurements of NPCs in the sagittal plane were evaluated. Intraobserver correlation coefficient, descriptive and frequency tests, Pearson Chi-Square, Independent t test and One-Way ANOVA tests were used to analyze obtained data. Results: The most prevalent variations observed in the axial, coronal, and sagittal sections were the one Stenson foramen, single canal, and funnel-type NPC, respectively. These variations exhibited no statistically significant correlation with demographic data. However, a statistically significant relationship (p<0.05) was identified between the demographic data and the morphometric measurements of NPC. Conclusions: This study, which investigates a restricted Turkish demographic, highlights that NPC displays a notable spectrum of morphological and morphometric diversities. It is recommended that a three-dimensional assessment of the NPC be conducted in order to prevent complications prior to any surgical procedures in the anterior maxilla, such as alveolar bone augmentation and implant surgery.
