Success of non-surgical root canal treatment is predicted by meticulous cleaning and shaping of the root canal system, three-dimensional obturation and a well-fitting‚ leakage-free coronal restoration. Various techniques have been developed to achieve the proper obturation of root canal system including the lateral compaction, vertical compaction and carrier based obturation. Over the years, pitfalls with one technique have often led to the development of newer methods of obturation. This article presents the case report of endodontic obturation by means of thermoplasticized gutta percha by using ThermaFil system along with Thermaprep oven in two different cases to achieve 3- dimensional hermetic seal. Thermafil provides a void free obturation with higher degree of homogeneity and less working time.
