“…Traditionally, two-dimensional methods such as intraoral radiography and panoramic imaging have been proposed in the literature for diagnostic imaging of the anterior maxilla, but they may not be sufficient to show anatomic variations because of their magnification and distortion. Recently, cone-beam computed tomography (CBCT) has allowed detailed three-dimensional (3D) evaluations of anatomical configurations of the various anatomical structures [10,26,35,38,43,45] and determination of the degree of resorption of buccal bone thickness (BBT) in the anterior maxillary region after tooth loss in detail [7,44]. It is important to bear in mind that the NPC can occupy 58% of the BBT [25], and the 3D anatomical features of the NPC need to be precisely defined to ensure safe and accurate surgical planning and placement of dental implants [38].…”

These anatomical changes in terms of dimensional and morphological parameters revealed the importance of three-dimensional imaging. Dentists should know and consider the variations in this canal in order to avoid possible complications during anaesthesia and surgical procedures which were applied to the maxillary anterior region. More precautions should be taken during surgical procedures in females, elderly and edentulous patients.

“…The canal contains the nasopalatine (incisive) nerve and the terminal branch of the descending nasopalatine artery, as well as fibrous connective tissue, fat, and even small salivary glands (Keith 1979;Liang et al 2009). Nevertheless, anatomical variations of the nasopalatine canal are not very well documented in the literature and are often presented as case reports (Jacobs et al 2000;Mraiwa et al 2004;Rodrigues et al 2009;).…”

The present study demonstrates decreasing values for the coronal width of the buccal bone wall in patients with missing central incisors and a time span since tooth loss of over 1 year. The age of the patients had a significant influence only on the length of the nasopalatine canal, with the mean values generally decreasing with an increasing age. The limited CBCT scans with FOVs varying between 4 × 4 and 8 × 8 cm are a valid diagnostic alternative to cross-sectional imaging in the anterior maxilla for dental implant treatment planning.

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.
