In vitro evaluation of the Thermafil technique with and without gutta percha coating.
To determine the sealing ability of the Thermafil technique with and without gutta percha on the plastic carrier, 40 maxillary incisors were divided into four treatment groups: (A) Thermafil with gutta percha on the carrier; (B) Thermafil without gutta percha on the carrier; (C) lateral condensation with standardize gutta percha; and (D) a single standardized gutta percha cone. Average leakage in groups A-D were 0.64 mm, 1.32 mm, 0.53 mm, and 0.72 mm, respectively. The only significant difference was between the Thermafil without gutta percha and the other three groups (p < 0.05).
