Evaluation of the diffusion capacity of calcium hydroxide pastes through the dentinal tubules
(2009-12-08)
This study aimed to evaluate the diffusion capacity of calcium hydroxide pastes with different vehicles through dentinal tubules. The study was conducted on 60 extracted single-rooted human teeth whose crowns had been ...
Crown-down preflaring in the determination of the first apical file
(Sociedade Brasileira de Pesquisa Odontológica, 2010)
In this study, scanning electron microscopy (SEM) was used to evaluate the adaptation of the first apical file after preflaring in mesiobuccal (MB) and mesiolingual (ML) canals of mandibular molars considering the tactile ...
Effect of root canal filling material and level of surgical injury on periodontal healing in dogs
(Munksgaard Int Publ Ltd, 1998-10-01)
Some divergencies in the literature about periodontal healing after surgical injury stimulated the development of this experiment. The root canals of dogs' teeth were negotiated and filled by the lateral condensation ...
Microbial distribution in the root canal system after periapical lesion induction using different methods
(2008-12-01)
The aim of this study was to evaluate the microbial distribution in the root canal system after periapical lesion induction in dogs' teeth using different methods. Fifty-two root canals were assigned to 4 groups (n=13). ...
Factors that favor tridimensional and hermetic obturation of root canal system
(2014-01-01)
Objective: This study aims at demonstrating the possibility and importance of filling different types of accessory canals in different teeth. Methods: The sample comprised 11 cases in which detailed knowledge of the inner ...
Influence of apical enlargement in cleaning and extrusion in canals with mild and moderate curvatures
(2011-07-06)
Optical microscopy and morphometric analysis were used in this study to evaluate, in vitro, the cleaning of the apical region in root canals with mild or moderate curvatures subjected to biomechanical preparation with a ...
