Análisis del conducto nasopalatino utilizando tomografía Cone Beam pacientes edentulos total y parcial Guayaquil 2018.

Abstract

Background: Several studies about the anatomy of the nasopalatine conduct describe a prevalence of his diameter about 1.40mm to 5.90mm2 and an average length of 4.6 to 15.7mm10. No studies of this type have been reported in the Latin American region and the Ecuadorian population. The knowledge of the anatomy of this sector is vital for the accomplishment of surgical interventions without complications and of high quality. Currently, the practice of dentistry is carried out through bibliographic evidence that supports it. Objective: The aim of this study is analyze the anatomical variants of the nasopalatine duct using Cone beam tomography and, at the same time, its relationship between patients with missing teeth and dentate patients in the population of Guayaquil.Materials and methods: This is a cross-sectional, observational, retrospective study in which 221 cone beam CT scans obtained during 2017 were covered. A total of 221 nasopalatine canal samples were analyzed in order to determine their anatomical variants in terms of diameter, accessory ducts, frequency of trifurcations and its vertical length. Results: 221 (100%) nasopalatine ducts were identified within the sample and significant differences were found in the diameter of the nasopalatine duct in relation to the absence and presence of teeth p = 0.04, as well as variability in nasopalatine duct length. to age ranges between 18 to 61 years old and from 61 years to 80 years onwards with a significant difference p = 0.008. Conclusions: This study showed that the nasopalatine duct undergoes anatomical variations in diameter, accessory ducts and length in edentulous jaws, with respect to dentate patients.
