Finite element analysis of the effects of thermal obturation in maxillary canine teeth

ObjectiveThe 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.Study designThe 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°C and 100°C were considered.ResultsBy using the virtual model and the simulation technique, the maximum temperature in the periodontal ligament was found to be 43.5°C.ConclusionsWithin 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.
