“…Kotaro et al [15] in their study found out that the average mesiodistal diameter of the incisive fossa was 3.3 mm and 2.8 mm in males and females respectively. Matsumura et al [16] in their study measured it as 3.1 mm and 3.3 mm in males and females respectively.…”

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.

“…In our study, the MP width was found to be 2.25 mm in accordance with the literature. Ito et al [ 23 ], Al-Amery et al [ 21 ], Friedrich et al [ 20 ], and Tözüm et al [ 22 ] reported that this value was higher in men. Kajan et al [ 24 ] and Thakur et al [ 25 ] reported that the width of the canal was not statistically significant according to gender.…”

“…It was observed that the measurements of the NPC in the sagittal section were frequently performed in the studies, but there were a limited number of studies in which the measurements were performed in the coronal section. Panjnoush et al [ 10 ] and Ito et al [ 23 ] reported that there was no statistically significant difference between IF and SF widths and gender, age, or dental status. In our study, there was a statistically significant difference between IF, SF widths, and age and gender.…”

Objectives:The objective of this retrospective study was to evaluate the anatomy and morphology of the nasopalatine canal in axial, sagittal, and coronal sections with cone-beam computed tomography and to appraise the effect of gender, age, and dental status on the nasopalatine canal. Material and Methods: Overall 1000 patients with cone-beam computed tomography (CBCT) images were analysed retrospectively. The morphology of the nasopalatine canal (NPC) was classified according to sections. Its sizes were measured, and variations were evaluated. The variables obtained were statistically analysed. Results: It was observed that the most common NPC shape was the cylindrical type (47.1%) in sagittal sections, and the C-shaped canal (51.1%) in coronal sections. In the axial section, two Stenson foramen (45.2%) were observed most frequently, and the most common form was found as oval (60.7%). In sagittal sections, statistically significant differences were obtained between all morphometric measurements and shapes of the NPC except the angle of the canal. It was found that all morphometric measurements in sagittal and coronal sections were higher in men. Also, it was found that the NPC angle and NPC length decreased with tooth loss. Conclusions: The nasopalatine canal shows many variations, and its dimensions differ according to gender, age, and dental status. For this reason, before the surgical procedures are applied to the maxilla, it should be evaluated radiologically to prevent complications.

This study estimates and quantifi es the prevalence of soft tissue calcifi cations using CBCT scans of patients. CBCT scans of 624 patients were viewed for evidence of visible soft tissue calcifications of orofacial region. Axial, coronal and sagittal orthogonal CBCT views were analyzed. Data regarding age of the patient, gender, presence or absence of calcifi cation and type of calcifi cation were recorded. The data was analyzed by using unpaired t test and chi-square test. The number of CBCT scans with the evidence of calcifi cation was 159 (25.48%). Most common calcifi cations were arteriosclerosis (45.91%) and calcifi ed atherosclerotic plaques (31.45%). Females had more percentage of calcifi cations which was statistically significant. CBCT may prove to be a helpful and early diagnostic tool in detecting soft tissue calcifi cations.
