Análisis de la transportación apical utilizando la técnica de instrumentación manual y reciprocante (WOG) : Revisión sistemática.

Abstract

Introduction: Is important that during the instrumentation of the root canal maintain the original anatomy as much as possible, avoiding complications. Apical transportation is produced by the tendency of the instruments to straighten during instrumentation, which leads to the removal of more structure in a wall. Aim: Identify between the manual and reciprocating instrumentation technique which generates greater apical transportation Materials and methods: The present research is systematic review of articles found in the search engines Pubmed, Google Scholar, Science Direct, and Elsevier using MESH terms. Results: WOG obtained 18% apical transport followed by K file with 37% and K flexofile 45%. Thus, it was also analyzed that WOG has higher centricity with 43%, followed by K flexofile with 33% and K file 24%.K flexofile files demonstrated greater transportation at 1.5mm distance with 0.385mm of apical transportation. The WOG files showed less transportation at a higher degree of curvature. A significant difference in apical transportation was found with the group that didn’t make glide path. Conclusion: Apical transportation can be affected by different variables. The instrumentation with the WOG files showed less apical transportation, less transportation under moderate / severe curvatures, and higher centricity compared to manual instrumentation with the K file and K flexofile files. The relationship of distance and transportation was variable according to the type of file. It can be related that not perform glide path generates apical transportation.
