Abstract
Temperature elevation on external surfaces of a low-temperature Ultrafil system cannula and on the surface of extruded thermoplasticized gutta-percha mass was studied. The Ultrafil cannula warmed for 15 min exhibited a mean surface temperature o f82.26 °C immediately after withdrawal from the heater. The highest cannula metal applicator surface mean temperature o f34.52 °C was recorded after 8 s. Temperature of
the gutta-percha mass extruded from the cannula was observed to fluctuate. Thus, the highest mean temperature of 53.90 °C at the needle orifice and 45.22 °C at the gutta-percha mass extruded for 3-5 mm, was recorded after 12 and 8 s, respectively.
