The TC system presented the greatest thermoplasticity values (p<0.05). RESULTS: The resulting data were analyzed by ANOVA. The flow capacity of each material was confirmed by the difference between the initial and final areas of each sample. Images of the specimens before and after compression were digitized and analyzed by the Image Tool software. Following that, they were positioned between two glass slabs and each set was compressed by a 5kg weight. Specimens were placed in water at 70✬ for 60 seconds. MATERIALS AND METHODS: Standardized specimens were fabricated from the materials to be evaluated. OBJECTIVE: The aim of this study was to evaluate the thermoplasticity of three commercial brands of gutta-percha (Tanari, Dentsply 0.06, and Roeko), and of the TC system.
