Using the self-etch adhesives in anterior restoration
(2012-05-01)
With the arrival of self-etch adhesives systems, there has been a rise in interest among clinicians, making it imperative for health professionals to have knowledge of the properties, characteristics, the association as ...
Aplicação da técnica de condicionamento total ou de primers autocondicionantes em dentes decíduos após abrasão a ar
(2005-07-01)
Since the use of air abrasion has grown in pediatric dentistry, the aim of this study was to evaluate, by means of shear bond strength testing, the need to use the total etching technique or self-etching primers on dentin ...
Length of resin tags in pit-and-fissure sealants: all-in-one self-etching adhesive vs phosphoric acid etching.
(2008-04-01)
PURPOSE: To investigate the penetration (tags) of adhesive materials into enamel etched with phosphoric acid or treated with a self-etching adhesive, before application of a pit-and-fissure sealant. MATERIALS AND METHODS: ...
Effect of hydrofluoric acid etching duration on the roughness and flexural strength of a lithium disilicate-based glass ceramic
(2011-05-13)
The aim of this study was to examine the effect of different acid etching times on the surface roughness and flexural strength of a lithium disilicate-based glass ceramic. Ceramic bar-shaped specimens (16 mm x 2 mm x 2 mm) ...
Tensile bond strength of self-etching versus total-etching adhesive systems under different dentinal substrate conditions
(2007-01-01)
The use of acid etchants to produce surface demineralization and collagen network exposure, allowing adhesive monomers interdiffusion and consequently the formation of a hybrid layer, has been considered the most efficient ...
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 ...
Composite pontics for orthodontic patients with extraction spaces.
(2010-06-01)
Esthetic orthodontic appliances continue to appeal to more patients, which results in objections to extraction spaces that remain for several months during orthodontic therapy. This has led orthodontists to design temporary ...
Influence of concentration, time and method of application of citric acid and sodium citrate in root conditioning.
(2012-05-01)
The aim of this study was to establish the parameters of concentration, time and mode of application of citric acid and sodium citrate in relation to root conditioning. A total of 495 samples were obtained and equally ...
Shear bond strength of orthodontic brackets bonded using halogen light and light-emitting diode at different debond times
(2010-01-01)
The aim of this in vitro study was to compare the photoactivation effects of QTH (Quartz-Tungsten-Halogen) and LED (Light-Emitting Diode) on the SBS (Shear Bond Strength) of orthodontic brackets at different debond times. ...
Anterior restorations in bleached teeth: Difficulty establishing the color after bleaching
(2012-12-01)
It is becoming more common for patients to look for cosmetic procedures in dental offices. The search for lost or desired esthetics by patients is increasingly frequent and the professional must be able to meet this demand. ...
