Investigation of the Effect of Sealer Use on the Heat Generated at the External Root Surface during Root Canal Obturation Using Warm Vertical Compaction Technique with System B Heat Source
(Elsevier B.V., 2014-04-01)
Introduction: During warm vertical compaction of gutta-percha, root canal sealers with different chemical compositions absorb the heat generated inside the root canal. The aim of this research was to assess physicochemical ...
Simulação numérica da convecção natural em cavidade porosa bi-dispersa aquecida por baixo
(Universidade Tecnológica Federal do ParanáCuritibaBrasilDepartamento Acadêmico de MecânicaEngenharia MecânicaUTFPR, 2013-04-23)
In this work it is investigated the transport phenomenon by heat transfer through natural convection in a bi-disperse square cavity heated from below. The cavity is represented by porous, square, disconnected blocks uniformly ...
