“…They stated that the enlargements were mainly due to bone loss after tooth extraction. In another study, 10 examined the NPC morphometric and volumetric measurement in anterior edentulous and anterior dentate in cone beam CT images. They found that there was no relationship between two dentition status and NPC volume.…”

“…8 It is stated that CT is preferred because it can transfer information in three dimensions, and distortions and superpositions are less common than in conventional radiography. 8,9 Although there are articles in the literature using cone-beam CT for NPC morphology 10,11 , and cone beam CT has a relatively lower radiation dose comparing with medical CT, CT images were preferred in this study because the contrast resolution of CT was higher than that of cone-beam CT. 12 Anatomical variations in the NPC; the form, length, location, and incisive foramen (IF) diameter; the number of openings in the nasal fossa; and other morphological changes have been evaluated in the literature. 11,13 However, there are few articles evaluating the relationship between dentition and NPC morphology in the literature.…”

Objective: The nasopalatine canal (NPC) is one of the important anatomic structures in anterior maxilla. The aim of this study was to evaluate the changes in NPC morphology according to dentition status in the maxillary anterior region by computed tomography (CT). Methods: Computed tomography images of 100 patients were screened retrospectively. Images were divided into two groups by dental status: an edentulous group (EG) of 50 patients who have edentulous premaxilla and a control group (CG) of 50 patients who have all incisor teeth in the premaxillary region. After recording the age, sex, and dentition status of the patients, the NPC diameter, NPC length, incisive foramen (IF) diameter, and angle between the NPC and palatine bone were measured in sagittal sections, and the number of NPCs was determined in axial sections. Results: There was no significant difference between NPC angle and dentition status (p=0.151). The NPC diameter was significantly higher in the EG (p=0.002), as was the IF diameter (p=0.041). In addition, NPC length was significantly higher in the CG (p<0.001). A statistically significant and negative correlation was found between age and NPC length (p<0.001), and a positive correlation was found between age and NPC diameter (p=0.004). In addition, no statistically significant difference was found between sex and other parameters (p>0.05). Conclusion: The NPC length and diameter vary according to the age and dentition status of the patient. Changes in this anatomic structure should be evaluated pre-operatively in elderly patients by three-dimensional radiographic evaluation.

“…In addition to linear assessments in the sagittal and axial planes using images obtained by CBCT, in this paper, volumetric calculations of the NPC were also performed, thus presenting a simultaneous three-dimensional analysis. NPC volume analysis does not change with the tomographic plane studied, this ensures greater morphological precision (Demiralp et al, 2018), and can reduce trans-operative accidents, including problems.…”

“…Using the 3D-Doctor software (Able Software Corp, Lexington, MA, USA), measuring the segmentation of the digital image based on vectors it is possible to perform cubic NPC measurements (Acar & Kamburoğlu, 2015;Demiralp et al, 2018). The NPC volumetric calculation in the current study was performed using the ROI tool in the Horos software.…”

“…NPC measurements were compared between females and males (Table 1), between toothed male and female participants (Table 2), and between edentulous male and female participants (Table 3). Toothed participants were considered individuals presenting dental elements 12, 11, 21, and 22 (Demiralp et al, 2018). Edentulous participants lacked these teeth.…”

Objective: Development and validation (using open source software) of a method for volumetric and linear assessment of the nasopalatine channel (NPC) using cone beam computed tomography (CBCT). Materials and methods: This was an observational, cross-sectional study of 276 CBCTs. Acquisition was performed on a Prexion 3D computerized tomography scanner (manufacturer), using voxels of 0.08 mm and 0.14 mm, (with FOV at 5 and 12 cm). The images were compiled and divided in accordance with gender and the dental condition of the maxilla. Evaluation took place on a MacBook Pro computer using the Horos Project program (Version 3.3.5). Linear measurements and NPC volumetric evaluations were performed after correcting the orientation axes (sagittal and axial). The length and ROI volume tools were used. Results: The average age for men was 60.15 ± 11.94, for women it was 59.95 ± 10.63. Respectively, for men and women, the average NPC volume values were: 68.59 mm3 and 59.37 mm3 (p = 0.032), for length they were 10.08 mm and 8.84 mm (p = 0.000). Of the dentate participants, the NPC averages for volume for men and women were: 71.01 mm3 and 57.18 mm3 (p = 0.007), for length they were 10.26 mm and 9.14 mm (p = 0.001). In the edentulous, the average NPC lengths were 9.79 mm (men) and 8.37 mm (women) (p = 0.005). Conclusion: For linear and volumetric nasopalatine channel assessment, the post-processing method used in the Horos software was considered precise and easy-to-use.

Background:This study aimed to evaluate the morphological characteristics of the anterior maxillary nasopalatine canal and the width of the buccal bone using cone-beam computed tomography (CBCT) in 150 adults in Northern Cyprus. Material/Methods:The study included 150 participants, and their anterior maxillary morphometric measurements (eg, length of the nasopalatine canal and anteroposterior diameter of the nasal foramen) were taken using CBCT with the scanning parameters of 90 kvP, 24 s, 4 mA, voxel size 0.3 mm, and field of view 10×6 cm. The shapes of the nasopalatine canal (NPC) were categorized into 4 types: cylindrical, hourglass, funnel-shaped, and banana (54%, 20.6%, 18.6%, and 4%, respectively). Results:The findings showed a clear link between the shape of the NPC and the horizontal dimensions of the anterior maxilla's morphometric properties. In general, decreased horizontal bone dimensions were found in the premaxilla at the banana-and funnel-shaped type for the nasopalatine canal. Also, the anteroposterior diameter of a nasal foramen in the hourglass shape was significantly larger in diameter than all other shapes. Additionally, the morphology of the nasopalatine canal is influenced by its shape. The sagittal cross-section has shown significant correlations with the sizes of the incisive foramen, nasal foramen, and the length of the nasopalatine canal. Conclusions:The study found a correlation between the shape of the NPC and the horizontal dimensions of the anterior maxilla's anatomy. The measurements of NPC in a North Cyprus population slightly differ from the established standards found in the existing literature. Conducting more extensive studies with a larger number of CBCT images will offer additional insights.
