The effect of temperature on self-etching adhesive penetration.
(2006-10-01)
The purpose of this study was to investigate the penetration of an aggressive self-etching adhesive system at refrigerated and room temperatures into ground and unground enamel surfaces. Thirty extracted human teeth were ...
Unrestricted linear dimensional changes of two hard chairside reline resins and one heat-curing acrylic resin
(1996-12-01)
The selection and use of hard chairside reline resins must be made with regard to dimensional stability, which will influence the accuracy of fit of the denture base. This study compared the dimensional change of two hard ...
In vitro evaluation of surface roughness of 4 resin composites after the toothbrushing process and methods to recover superficial smoothness.
(2007-05-01)
OBJECTIVE: This study evaluated the efficiency of repolishing, sealing with surface sealant, and the joining of both in decreasing the surface roughness of resin-based composites after a toothbrushing process. METHOD AND ...
Toothbrushing with vegetable oil: a clinical and laboratorial analysis.
(2004-04-01)
The dentifrices currently available in the marketplace contain many anticariogenic substances, fluoride and abrasives aimed to better clean the dental surface, remove dental plaque, improve salivary flow and its buffer ...

Reducing the Experiments Required to Assess the Performance of Metaheuristic Algorithms
(Revista Computación y Sistemas; Vol. 14 No.1, 2010-09-30)
Abstract. When assessing experimentally the performance of metaheuristic algorithms on a set of hard instances of an NP-complete problem, the required time to carry out the experimentation can be very large. A means to ...
Comparative analysis of human and bovine teeth: Radiographic density
(2008-12-01)
Since bovine teeth have been used as substitutes for human teeth in in vitro dental studies, the aim of this study was to compare the radiographic density of bovine teeth with that of human teeth to evaluate their usability ...
