Purposes:To determine the anatomical variability of the incisive canal (IC) and to clarify its characteristics, using cone beam computed tomography (CBCT) evaluation, in order to avoid intra-and post-operative complications in oral surgery. Materials and Methods:The diameter, length and angulations of the IC and the width of the bone anterior to the canal were measured on 100 digital CBCT using the Galileos Implant 1.9 software. The patients' ages ranged from 14 to 54 years (53 males and 47 females). The data were analyzed using the Stat View 5.0 software. Results:The anatomy of the IC shows a large variability in its morphology and dimensions, with the canal branching into up to four canals at the nasal level. The length of the IC varies from 4.94 mm to 26.13 mm with an average of 11.42 (±2.71) mm with a statistically significant difference between genders. The ICs were classified into 6 categories according to their shape viewed on the sagittal sections, with two new shapes found. The incisive foramen has four shapes with a statistical correlation with the gender of the subject. The bone thickness anterior to the canal shows a statistical correlation with the gender of the subject and the presence or absence of the central incisor. Conclusions:The present study highlights an important variability in the anatomy and morphology of the IC. Therefore, a CBCT analysis of this structure is essential to avoid any complications before any surgery in this area.

“…The oral opening of the NPC, the incisive foramen, is found in this region which maintains close proximity to the roots of the upper central incisors [4] [5]. In view of this anatomical relationship, thorough radiographic analysis is necessary during dental implant planning [5] [6].…”

Purpose: The study was performed to evaluate variability in nasopalatine canal using cone beam computed tomography (CBCT) in relation to age and gender. The study also provides an insight while considering anterior maxillary implants. Materials and Methods: The study included 200 subjects aged between 19 and 67 years who were divided into the following 3 groups: 1) 19 -34 years old; 2) 35 -49 years old; 3) >50 years old. The male and female subjects were 104 and 96 respectively. After obtaining a prior consent, CBCT was performed using a standard exposure and patient positioning protocol. The CBCT volume was sliced in three planes (X, Y, and Z) and was sequentially analyzed for the location, morphology and morphometric dimensions of the nasopalatine canal. The correlation of age and gender with all the variables were evaluated. Results: The present study revealed statistically significant differences in the length of the nasopalatine canal based on the age group. The slanted and the cylindrical variety of the nasopalatine canal were commonly observed in the study. However, no statistical differences were noted in the other variables such as number of openings at the nasal fossa, diameter of the incisive fossa, angulation of the canal as viewed in the sagittal sections and antero-posterior dimensions of the canal in the sagittal sections. Conclusion: The present study demonstrates the variability observed in the anatomy and morphology of the nasopalatine canal which is an important landmark for placing dental implants in the anterior maxillary region.

“…4,5) The mean antero-posterior angulation at the inferior level was 75.3 degrees in IIIC, and the value was close to that of adults (mean: 74.3 degrees) in a previous study. 4) The mean difference of angulation between the inferior and middle levels was lower in IIA and IIC, and it was understood that the maxillary incisive canal was straight from the inferior level to nasal floor.…”

Summary:The maxillary incisive canals were observed in childhood from infancy to school-aged children to clarify their development. Cone-beam computed tomography was performed to investigate 44 dry child skulls. Two-dimensional images of various planes in the maxillary incisive canal were reconstructed on a computer using 3-dimensional visualization and measurement software. Then, antero-posterior angulation, and antero-posterior and lateral axes of the maxillary incisive canal were measured at the inferior and middle levels. The mean difference of angulation between the inferior and middle levels was 2.3 degrees in IIC, and 11.1 degrees in IIIC. The mean ratio of the lateral axis to antero-posterior axis at the middle level was 2.54 in IIC, and 1.93 in IIIC. In conclusion, it was antero-posteriorly straight from IA to IIC, and, after IIIA, it curved at the middle level. The cross-sectional shape in IIC was depressed with a larger lateral axis.
