Abstract

Background: With regards to the increasing use of implants in the field of dentistry, the recognition of critical landmarks is essential. Nasopalatine Canal (NPC) is one of these important indices, which due to high esthetic expectations in premaxilla, should be precisely evaluated before surgery. Objectives: This study aimed to evaluate the morphological and anatomical variations of the NPC. Materials and Methods: A total of 326 individual cone beam computed tomography (CBCT) images were analyzed in sagittal, coronal, and axial planes in order to evaluate the dimensions, morphology and anatomic features of the NPC. The canal shape, length, and curvature, incisive and Stenson’ s foramina (SF) dimensions, and the number of openings on both sides of the canal were assessed. The correlation of age, gender, and dental status with all considered parameters were analyzed. Results: The most dominant shape of theNPCwas cylindrical (65. 33%). ThemeanNPClength was 12. 85 2. 63mm, which was greater in men and showed significant differences between two genders (P < 0. 001). The most frequent canal anatomical variation in the coronal plane was Y-type (50%). Through statistical analysis, the effect of gender on the canal length, anteroposterior dimension of SF, and mediolateral dimension of SF and Incisive Foramen (IF) and the number of orifices at the nasal floor was significant. Also, a significant relationship existed between dental status and curvature of the canal, anteroposterior dimension of IF and SF and furcation level of the canal. Conclusion: This study has highlighted the anatomical variations of NPC regarding its dimension, location and morphological appearance. Cylindrical was the most common shape followed by funnel-shape, hourglass, and spindle, which were the other canal shapes with less frequency, respectively. The results suggest significant relationship between NPC, and gender and dental status. The influence of age was not as significant as gender and dental status.
