Evaluation of nasopalatine canal using cone beam computed tomography - A retrospective study

Abstract

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.

Significance of morphometric and anatomic variations of nasopalatine canal on cone-beam computed tomography in anterior functional zone - A retrospective study

“…Mean anteroposterior dimension was increasing with increase in age group, but difference in different age groups was statistically not significant. The findings were supported by findings of Panda et al [ 2 ] and Thakur et al ,[ 8 ] Gopal and Kapoor,[ 19 ] and Sathvik et al ;[ 20 ] however, the difference in values was statistically nonsignificant gender wise and age wise. On the contrary, statistical significant results were found in the study conducted by Görürgöz C et al [ 1 ]…”

“…Gender wise no statistically significant difference was seen in mesiodistal dimension of IF; however, the mean diameter was greater in males. Panda et al ,[ 2 ] Rao et al ,[ 17 ] Khojastepour et al ,[ 18 ] and Gopal and Kapoor[ 19 ] also reported similar significant differences. Age-wise mesiodistal dimension was increasing with increase in age group, and difference was statistically highly significant ( P = 0.007).…”

“…Our study revealed the length of NPC was greater in males, and gender-wise difference was statistically very highly significant ( P < 0.001). Song et al ,[ 9 ] Mraiwa et al ,[ 13 ] Khojastepour et al ,[ 18 ] and Gopal and Kapoor[ 19 ] also reported comparable significant sexual differences. They also concluded the greater length of the NPC in the males could be ascribed to the relatively larger craniocaudal dimension of the face observed in the males.…”

Nasopalatine Canal Masquerading as a Periapical Cyst

“…Gopal and Kapoor[ 9 ] reported that the mean labial cortical bone at palatal, middle, and nasal levels was 6.22 ± 1.73 mm, 6.9 ± 1.87 mm, and 13.48 ± 41.82 mm, respectively. The mean palatal cortical bone at palatal, middle, and nasal levels was 2.87 ± 0.78 mm, 4.48 ± 1.06 mm, and 6.22 ± 1.67 mm, respectively; these results were consistent with our case report which ranges from 1.91 mm to 6.91 mm.…”
