Evaluation of subcutaneous and alveolar implantation surgical sites in the study of the biological properties of root-end filling endodontic materials
(2010-01-01)
Objective: The aim of this study was to compare two methodologies used in the evaluation of tissue response to root-end filling materials in rats. Material and Methods: Forty rats were divided into 4 groups: in Groups I ...
Radiopacity of restorative materials using digital images
(2006-07-06)
The radiopacity of esthetic restorative materials has been established as an important requirement, improving the radiographic diagnosis. The aim of this study was to evaluate the radiopacity of six restorative materials ...
Micro-computed Tomography Analysis of the Effect of Immersion Time on Volumetric Stability of Different Endodontic Materials
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2020-01-01)
Dental materials should be stable over time. This study investigated volumetric change of the root canal sealers AH Plus, Fill Canal, and Sealapex; and the root-end filling materials Biodentine, IRM, and MTA after different ...
In vitro study of staining agents effects on optical properties of esthetic restorative materials
(2010)
The authors have studied the effect of four staining agents on the optical properties of esthetic restorative materials through translucency tests. Two commercial brands of composite resins were used: Point 4 (Kerr) and ...
Periapical repair after root canal filling with different root canal sealers
(2009-12-01)
The aim of this study was to evaluate periapical repair after root canal filling with different endodontic sealers. Sixty four root canals from dog ́s teeth were filled, divided into 4 groups (n=16). Root canals were ...
Adherence of Streptococcus mutans to uncoated and saliva-coated glass-ceramics and composites
(2008-11-01)
This study sought to investigate the surface roughness and the adherence of Streptococcus mutans (in the presence and absence of saliva) to ceramics and composites. The early dental biofilms formed in situ on the materials ...
Effects of thermocycling on mechanical properties of soft lining materials.
(2009-12-01)
Soft linings are materials used to reduce the tension and forces of mastication, forming all or part of the fitting surface of a denture. This study evaluated the effect of thermocycling on water absorption, solubility, ...
Selecting the most adequate bedding material for broiler production in Brazil
(2012-04-01)
Broiler chicken production is widely dispersed across the globe, and one important issue for growers is the selection of adequate bedding material, as the availability and price of substrates varies among countries and ...
