title: Quality analysis of the root canal filling employing gutta-percha thermoplasticized at a low temperature (Ultrafil system).
abstract: The objective of this study was the investigation of the sealing properties of gutta-percha thermoplasticized at a low temperature by either employing or not N-Rickert cement and vertical condensation. Methylene blue at 0.5% was used to demonstrate the apical leakage. Results demonstrated that minor penetration indexes were attained when cement was not employed and vertical condensation was accomplished.
