“…In the present study, the anteroposterior diameter of the incisive foramen was measured as 4.79±1.26 mm, and the mediolateral diameter was measured as 3.29±1.09 mm. This is similar to the results of a study by Salemi et al [19] in that the incisive foramen was found to be ovalshaped, with a larger anteroposterior than mediolateral diameter. In addition, the diameters https://doi.org/10.5051/jpis.2020.50.1.48…”

Purpose: The purpose of this study was to utilize cone-beam computed tomography (CBCT) image analysis to obtain anatomical information related to the morphology of the incisive foramen to provide useful data regarding implant placement and clinical procedures such as anesthesia. Methods: The study included 167 patients who underwent CBCT scans over 20 years. Three components were measured: 1) the anteroposterior and mediolateral diameter of the incisive foramen, 2) the horizontal bone thickness anterior to the incisive foramen, and 3) the vertical bone height coronal to the incisive foramen. All measurements were expressed as mean±standard deviation and were analyzed by a single examiner. Results: The anteroposterior diameter of the incisive foramen was wider than the mediolateral diameter (P<0.001). The diameter of the incisive foramen in patients in whom the central incisors were present was smaller than that in those in whom at least one central incisor was absent, but no statistically significant difference between the groups was observed. The horizontal bone thickness in the patients with central incisors was statistically significantly larger than that in the patients without at least one central incisor (P<0.001). The same pattern was observed with regard to vertical height, but that difference was not statistically significant. Conclusions: The buccal bone thickness anterior to the incisive foramen was significantly decreased after central incisor loss. It is necessary to identify the morphology of the bone and the location of the incisive foramen via CBCT to avoid invasion of the incisive foramen and nasopalatine canal.

“…The mean length of nasopalatine canal in the present study was higher than that reported by some earlier research by Nasseh et al On contrary, the nasopalatine canal length in the present study was similar to that reported in two studies by Kajan et al (2015); Salemi et al (2016). [3,12] In the present study, the length of nasopalatine canal was shorter in females than in males but it was not statistically significant. On the other hand, few researchers: Kajan et al (2015); Tozum et al (2012); Nasseh et al (2017) reported that the length of nasopalatine canal was 1,12,13 significantly higher in males than females.…”

Background: Implantology is a very significant branch of dentistry that deals with the rehabilitation of edentulous patients. Thus, knowledge of anatomical variations of related neurovascular structures such as the nasopalatine canal is essential. Aim:The aim of study was to determine the form, length, and diameter of the nasopalatine canal using CBCT. Materials and Methods: In this retrospective study, images were archived from CBCT unit and visualized using Romexis software. The nasopalatine canals of 50 patients between the age range of 18-59years were analyzed. The shape of the nasopalatine canal, length of the nasopalatine canal and the diameter of incisive foramen were assessed in sagittal and coronal section. The width of labial and palatal alveolar bone around the canal and inclination of the nasopalatine canal to hard palate were evaluated. Statistics: (1) if there is any relation between the gender and the assessed parameters (2) if there is any relation between edentulous and partially edentulous patients with the assessed parameters. Results: The most common shape of the nasopalatine canal was cylindrical. The average length of the nasopalatine canal was 12.14±2.41 mm and the average diameter of incisive foramen 3.45±0.84 mm anteroposteriorly and 3.77±0.94mm mediolaterally. The average inclination of the nasopalatine canal to hard palate was 119.93±9.73° Conclusion: This study highlights the variations seen in the nasopalatine canal. The close vicinity of nasopalatine canal and implant can lead to sensory disturbances and damage of the tissues. Thus, a thorough knowledge before the surgical - implant procedure using cone beam computed tomography seems beneficial.

“…Khojastepour et al showed statistically significant differences in the length of the incisive canal between males and females where the mean lengths of the canals were 11.46 mm and 9.37 mm, respectively. Although limited by a small sample, the previously mentioned Lebanese study found that the length of the canal was shorter in females [ 3 , 21 - 23 ]. Additionally, the length of the canal also varies based on the height of the maxillary bone [ 22 ].…”

“…CBCT studies have demonstrated that maxillary tooth loss markedly reduces buccal bone plate thickness. Interestingly, this finding has been used to explain, with statistical significance, why the incisive canal’s width is positively correlated and its length negatively correlated with tooth loss/extraction and the aging of dentulous maxillae [ 3 , 13 , 15 , 20 , 24 ]. Khohastepur et al also pinpointed gender variances reporting that the alveolar bone thickness is higher in men than in women [ 20 ].…”

The incisive canal, also known as the nasopalatine canal, is an interosseous conduit through the anterior maxilla connecting the oral and nasal cavities. Within this canal lies the nasopalatine nerve and the vascular anastomosis between the greater palatine and sphenopalatine arteries. The embryology of the canal has led to interesting theories explaining its function. Efforts have been made to describe the morphometrics of the incisive canal by radiologic evaluation across sex and ethnicities. This paper aims to review the current literature on the embryology, anatomy, and clinical relevance of the incisive canal.
