Abstract

Introduction: Nasopalatine canal is a significant structure which has a prominent role during dental treatments such as extraction and implant placement. During extraction damage to the canal leads to trauma of the nerves and vessels of the canal causing paraesthesia of the premaxilla. And likewise while placing an implant, improper evaluation of the location of the canal might lead perforation causing the same former adverse effect along with improper osseointegration of the implant. Aim: The aim of the study is to assess the position and size of the nasopalatine duct using cone-beam computed tomography (CBCT) in dentulous and edentulous cases in Chennai population. Materials and Methods: The study is done using CBCTs collected from the Department of Implantology in Saveetha Dental College, Chennai. A set of 50 CBCTs are collected for the study without any gender bias and patient age ranging from 23 to 80 years. All the CBCTs are assessed in sagittal and coronal views for the dimensions of the nasopalatine canal. Results: As per the gathered data, the evaluated population has an age ranging from 23 years to 80 years and out of which 15 are male and 9 are female. The mean value of the canal from the anterior wall of the foramen to the anterior nasal spine in males is 14.69 mm and in females is 12.74 mm. The thickness of the buccal cortex from the foramen in males is 6.38 mm and females is 6.20 mm. Conclusion: There is a significant difference in the position and size of nasopalatine ducts in completely edentulous patients with respect to gender. Increased knowledge of this anatomic structure and its diversity leads to enhanced surgical procedures and reduced complications.
