Mechanized instrumentation of root canals oscillating systems
(2013-01-01)
Cleaning and shaping are important steps in the root canal treatment. Despite the technological advances in endodontics, K and Hedströen files are still widely used. In an attempt to be more effective in preparing the root ...
Improving minimum quantity lubrication in CBN grinding using compressed air wheel cleaning
(Elsevier B.V. Sa, 2012-12-01)
The application of minimum quantity lubrication (MQL) in grinding has emerged as an alternative for reducing the abundant flow of cutting fluids, thus achieving cleaner production. Although considered an innovative technique ...
Improving minimum quantity lubrication in CBN grinding using compressed air wheel cleaning
(Elsevier Science SaLausanneSuíça, 2012)
Platinum nanoparticles produced by EG/PVP method: The effect of cleaning on the electrooxidation of glycerol
(Elsevier, 2013-05)
Carbon supported Pt nanoparticles (NPs) have been prepared through polyols method using PVP. As observed with a large number of surfactants employed in NPs synthesis, it is very difficult to attain an efficient NPs cleaning, ...
An analytical method for selecting the optimal nozzle external geometry for fluid dynamic gauging
(Elsevier, 2011-08)
Fluid dynamic gauging (FDG) was developed to measure, in situ and in real time, the thickness of a soft deposit layer immersed in a liquid without contacting the surface of the layer. An analysis based on the lubrication ...
Effect of different rotary instrumentation techniques and thermoplastic filling on apical sealing
(Faculdade De Odontologia De Bauru - USP, 2004-03)
The aim of this study was to evaluate apical sealing after root canal treatment using two different rotary instrumentation techniques and two thermoplastic root canal filling techniques. The study was performed in 115 human ...
Influence of Hero Apical instruments on cleaning ovoid-shaped root canals
(Sociedade Brasileira de Pesquisa Odontológica, 2011)
The cleaning capacity of Hero 642 nickel-titanium files, complemented by the Hero Apical instruments in flattened roots, was determined by histological analysis, considering the area of action of the instruments on the ...
Method for determination of root curvature radius using cone-beam computed tomography images
(Fundação Odontológica de Ribeirão Preto, 2008)
This article describes and discusses a method to determine root curvature radius by using cone-beam computed tomography (CBCT). The severity of root canal curvature is essential to select instrument and instrumentation ...
Behavior of hardened steel grinding using MQL under cold air and MQL CBN wheel cleaning
(Springer, 2019-12-01)
Nowadays, environmental concern and the search for environmentally friendly techniques have contributed to industrial development towards sustainability. Production without social and environmental impact is one of the ...
