Resumo
Introduction and objective: The objective of the study was to compare the penetration of different commercial brands of gutta-percha and Resilon® in the lateral canals using the continuous wave technique (System B). Material and methods: We selected blocks of resin with simulated main canals, each with a lateral coronal canal and apical canal. A third lateral canal was made between these two, with the purpose of substituting the apical canal. A gutta-percha cone (Roeko®, SybronEndo® or Maillefer®) or Resilon® was thermoplastified in each lateral canal. After obtaining the radiograph, we took measurements in an image analyser and statistically analysed the data. Results and conclusions: Beyond the 2 mm of the System B point, none of the commercial presentations of gutta-percha or Resilon® demonstrated penetration. Statistically significant differences were found as regards the obturation of the upper lateral canal (p≤0.05), with Resilon® recording the highest penetration.
