Evaluation of the nasopalatine canal with cone-beam computed tomography in an Iranian population

Abstract

Background:Implant placement plays a vital role in oral rehabilitation following loss of the incisors. Thus, having knowledge of anatomical variations of adjacent neurovascular structures especially the nasopalatine canal (NPC) is essential. Due to the lack of basic information in Iran about the morphology of this canal and the probability of its variety in different populations, this study was designed on an Iranian population.Materials and Methods:In this descriptive study, we selected cone-beam computed tomography images of 198 patients comprising of 98 males and 100 females in two dental groups (edentulous or dentate). The shape of the nasopalatine foramen and the form of the canal in axial views were assessed. Then, the canal height and its diameter at the palatal, middle and nasal levels in cross-sectional images were measured. The available bone in the buccal and palatal sides of the canal was assessed. Data analysis was carried out using a Chi-square test and an independent t-test (P ≤ 0.05).Results:The majority of the samples (81.8%) presented a single foramen. Cylindrical shape (57.6%) was the most frequently detected canal form. The mean of the estimated canal height was 12.84 ± 2.88 mm. The canal diameter at the palatal level between the sexes and dental groups showed statistically significant differences.Conclusion:In our investigated population, the NPC form was mainly cylindrical with a single opening foramen. The mean of the canal height was higher than that found in other populations. Furthermore, the canal diameter in the edentulous group was greater than that observed in the other group.

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

“…The mean length of nasopalatine canal in the present study was higher than that reported by some earlier research by Nasseh et al On contrary, the nasopalatine canal length in the present study was similar to that reported in two studies by Kajan et al (2015); Salemi et al (2016). [3,12] In the present study, the length of nasopalatine canal was shorter in females than in males but it was not statistically significant. On the other hand, few researchers: Kajan et al (2015); Tozum et al (2012); Nasseh et al (2017) reported that the length of nasopalatine canal was 1,12,13 significantly higher in males than females.…”

Radiographic Assessment of Anatomy of Nasopalatine Canal for Dental Implant Placement: A Cone Beam Computed Tomographic Study

“…For the canal length, the inclination related to the hard palate, and the incisive foramen anteroposterior diameter, no statistical signifi cance between genders was observed except for the canal height that was found shorter in females. Kajan et al 14 in their study on Iranian population found that mean values for oral and nasal opening of NPC were 3.53 ± 1.01 and 3.7 ± 2.3 mm respectively, whereas in the present study, it was 3.38 ± 1.52 and 3.40 ± 1.02 mm in males and 2.90 ± 1.42 and 2.98 ± 1.00 mm in females.…”

“…For Al-Amery et al (3) and Kajan et al (7), the labiopalatal (anteroposterior) diameter of the IF was 2.80 ±0.82 and 3.53 ± 1.1 mm respectively.…”
