Objective: To evaluate the effectiveness of complementary protocols of sanitization in decontamination of infected root canals. Methods: A total of 50 single-rooted maxilary anterior human teeth were selected. The crowns ...
Onset of in vitro rhizogenesis response and peroxidase activity in Zingiber officinale (Zingiberaceae)
(Universidad de Costa Rica, 2001)
Successive media to improve the in vitro rhizogenesis of Nothofagus nervosa (Phil.) Dim. et Mil
(Springer, 2003-11)
In vitro rooting constitutes a difficult step during the micropropagation process of forest species. The successive media culture technique represents one way to overcome this barrier and includes modifying physical (e.g. ...
Structural resistance in immature teeth using root reinforcements in vitro
(Blackwell Munksgaard, 2005-06-01)
The purpose of this study was to evaluate in vitro the efficacy of root reinforcements by light-cured composite resin or zirconium fiber post in simulated immature non-vital teeth. Fifty-six bovine incisors teeth were used ...
Kinetics of zinc uptake and anatomy of roots and leaves of coffee trees as affected by zinc nutrition
(Taylor & Francis Inc, 2005-01-01)
Zinc (Zn) uptake kinetics and root and leaf anatomy were studied in coffee trees grown in nutrient solutions with or without Zn. Leaves and roots were sampled and cuts were made in the medium part of the leaves and in root ...
