“…Similar to our findings, some authors have not identified any significant difference between male and female subjects 3,10,13 However, others have reported a statistically significant difference in the length of the canal between males and females where males having longer canals. 4,5,7,9,11,12,14,[16][17][18] The average AP diameter of NPC in this study was 3.69 mm with a range of 2-6 mm which was similar to the figures reported by many others in the literature 1,[3][4][5]9,12,13,17 but higher than some others 4 and lower than in some studies. 15 This variation in the diameter may be due to the different populations studied and the variations in age.…”

Nasopalatine canal (NPC) is an important anatomical structure present in the anterior mid maxilla. It has the synonyms of incisive canal or anterior palatine canal. The objective of this study was to identify the morphometric characteristics of the NPC in group of Sri Lankan people using Cone beam computer tomography (CBCT) and to determine normal morphological course and anatomical variations. Fifty Maxillary CBCT images of anterior maxilla, obtained from the archives of the University Dental Hospital, Peradeniya were retrospectively analyzed to determine the position of the NPC. Morphology, canal dimension of NPC and its relation to the maxilla. Majority had a single opening (48%) or 2 openings (46%). Average diameter of the canal was 3.692 mm with a range of 2-6 mm. Majority of the canals had funnel shape and were vertically curved. Average length of canal was 12.142 mm and angulations of the curvature was 115.694 0 . Average antero-posterior diameter at nasal fossa was 2.852 mm, at mid-palate 2.366 mm and at hard palate 3.034 mm. Our findings were different from the findings reported in the literature. This may be due to the differences in ethnicity or limited size of sample. Within the limits of this study, we conclude that the form of the NPC is variable; predominantly funnel shaped with a single or two openings and with an average diameter of 3.7 mm in Sri Lankan population. Identification of variations in the position and shape will help in clinical practice specially in introducing local anesthetic block injections during dental treatment.

“…This is closer to the findings of others. 1,4,5,9,[11][12][13][15][16][17] Longer canals have been identified by many others, 10,14 Mean length of canal in a study conducted by Soumya et al, in 2019 3 was 18.63 ± 2.35 mm. Males in the present study had an average canal length of 13.49 mm which was longer than the females (10.99 mm).…”

“…However, Panda et al [ 2 ] and Panjnoush et al [ 7 ] found no significant relationship between gender and canal morphology. Age wise no statistical differences were obtained in our study; however, Görürgöz C et al ,[ 1 ] Salemi et al ,[ 4 ] Mishra et al ,[ 22 ] and Takeshita et al [ 23 ] found statistically significant difference between the age and length of the canal. The authors found that the canal length decreases with increasing age.…”

“…Panda et al [ 2 ] and Mraiwa et al [ 13 ] found similar funnel-shaped canals more common in their study and described that such canals lead to spreading out of the IF, so depending on the angle of implant placement, there is a risk of perforating the NPC and damaging the nasopalatine nerves and arteries. However, Thakur et al ,[ 8 ] Liang et al ,[ 10 ] and Mishra et al [ 22 ] reported cylindrical-shaped NPC in their studies. In another study, Etoz and Sisman found predominance of hour-glass shaped NPC.…”

Introduction: Oral rehabilitation in maxillary anterior region has increased concerns in the dental fraternity to have detailed morphological examination in treatment planning. The nasopalatine canal (NPC) along with its contents plays an important role in determining the prognosis of implants and their associated surgeries. The present study was performed to evaluate morphometric anatomic variations of the NPC using focused small field of view on cone-beam computed tomography (CBCT). Materials and Methods: The study included 250 participants. CBCT examination was conducted using standard exposure and patient positioning protocols. Sagittal, coronal, and axial sections were reviewed to determine NPC morphology and dimensions. Results: Single, round, incisive foramen with mean mesiodistal diameter of 3.23 (±1.00) mm, and mean anteroposterior dimension of 3.03 (±0.96) mm was found. Single Stenson's foramen along with funnel shaped, slanted NPC with mean angulation of 81.97 (±42.19), and mean length of 12.67 (±2.69) mm was found. Mean mesiodistal diameter at nasal fossa of NPC was 3.27 (±1.75) mm, at mid-level was 2.23 (±1.02) mm, at palate was 3.46 (±1.12) mm. At least one additional foramen was found. Discussion: Anatomy of the NPC is highly variable. Age-wise and gender-wise correlations revealed statistically significant results for different parameters. The present study highlighted significance of NPC along with its variations. Therefore, a methodical three-dimensional presurgical assessment is mandatory before any surgical intervention in this region.

“…The canal is present in the middle of the anterior maxillary region. It is a long slender passage and it connects the palate to the floor of the nasal cavity [1] . Canal continues in the oral cavity as a single incisive foramen posterior to the central incisor teeth and in the nasal cavity as the foramina of Stenson, which are two in number.…”

Aim: 1) to assess the morphological variation of the nasopalatine canal (NPC) concerning age and gender. 2). to assess the correlation between the gender and morphology of the canal. 3). to assess the correlation between age and length of the canal. Materials and Methods: This is a retrospective, randomized observational study. The study comprised of 60 CBCT scans of maxilla showing NPC completely. The patients were in the age range of 15-75 years. Scan of 25 females and 35 males were included in the study. Patient below 15 years of age and NPC pathology or impacted teeth in same region were excluded in the study. The scans were obtained using ICAT17-19 machine and analyzed Vision software. Cone-Beam 3D Imaging Machine operating at 120 kvp, 37.07 mAs with 0.25 mm voxel size, and a field of view of 16 × 6 cm maxilla. Results: Nasopalatine canal has 4 different morphological shapes. The most common shape was the cylindrical shape amongst both males and females. The least common shape was found to be hourglass shape with increasing age the length of NPC was found to decrease. The length of the canal was found to be longer in males when compared to females Conclusion: This study highlights the importance of NPC morphology before or during surgical procedures involving the maxilla.
