Interface strength of incremental placement of visible light-cured composites

Reduction of microleakage in class II composite resin restorations using retentive pins

“…Bondent® pins have a round retentive cap to ensure retention of the composite restorative material to the pin and to allow a relatively small length (2-5 mm) and diameter (0-52 mm), with optimum retention to dentine (0-43 mm drill). This is not the case with regular parapulpar threaded pins where longer pins are required for optimal retention (Podshadley, 1989).…”

“…At such sites, the enamel wall is thin, lacks regular prismatic configuration or is entirely missing. Several possible measures have heen proposed to minimize this phenomenon, namely, incremental composite resin insertion and polymerization (Podshadley, Gullett & Binkley 1985), use of dentine adhesives (Liberman era/., 1985), retention grooves in the proximal box (Ben-Amar, Metzger & Gontar, 1985), light curing from the apical direction aided by light-transmitting wedges (Lutz, Krejc & Oldenburg, 1986) and the rebonding technique (Judes etal, 1983). In many instances it is often difficult to apply the above techniques and a practical alternative is.…”

Avaliação da resistência à ruptura por tração entre resina composta e diversos adesivos dentinários

“…Semina: Ciências Biológicas e da Saúde, Londrina, v. 23, p. 67-76, jan./dez. 2002 Por outro lado, inúmeros trabalhos de pesquisa focalizam a resistência à tração de diversas resinas compostas reparadas, entre os quais situam-se autores como Lloyd et al (1971), Carneiro et al (1977), Consani, Stolf e Ruhnke (1977), Chan e Boyer (1983), Podshaley et al (1985), Tjan et al (1988), Gregory, Pounder e Bakus (1990), Gregory et al (1992), Swift, Le Valley e Boyer (1991), Turner e Meiers (1993), Nolasco et al (1996).…”

Marginal Sealing of Curing Contraction Gaps in Class V Composite Resin Restorations

“…W -ax W If a may not exceed the dentinal bond strength (5 MPa) or the interlayer bond strength (20 MPa) (Podshadley et al, 1985), X/w must be very small, as can be seen in Fig. 3, where the polymerization contraction stress is plotted as a function of the ratio X/w for some commercially available composite resins.…”
