title: Finite element analysis of the effects of thermal obturation in maxillary canine teeth.
abstract: OBJECTIVE
  The purpose of the present study was to determine the distribution and level of temperature, in a model of a maxillary canine, the surrounding periodontal tissues, and the bones, during a System B heat obturation technique simulation.
  
  
  METHODS
  The temperature distribution was determined by using a three-dimensional finite element analysis. The tooth was assumed to have undergone an endodontic treatment before the application. Heat applications of 200 degrees C and 100 degrees C were considered.
  
  
  RESULTS
  By using the virtual model and the simulation technique, the maximum temperature in the periodontal ligament was found to be 43.5 degrees C.
  
  
  CONCLUSIONS
  Within the assumptions and the limitations of the study, it was determined that the simulation of System B technique created no potentially harmful levels of temperature throughout the maxillary canine model.
