An In Vitro Assessment of Microleakage under Stainless Steel Bracket Bonded with Three Different Light-Cures Orthodontic Adhesives After Thermocycling and Water Storage
Author(s): Omaima Lateef Salman* and Reem Atta Rafeeq
Background: This in vitro study was conducted to assess the microleakage under stainless steel brackets bonded with three different adhesive systems at both adhesive interfaces occlusally and gingivally after thermocycling and two-month water storage duration. Materials and methods: A total of 48 sound human upper premolar teeth were selected and arbitrarily allocated into 3 equal groups on the basis of the adhesive system used as; T, S and G groups of 16 teeth each, group T, Transbond XT adhesive; group S, Transbond XT self-etching primer; group G, resin-modified glass ionomer adhesive (GC Fuji ORTHO LC). All specimens in groups T, S and G were framed in different colored coded acrylic blocks; pink, yellow and green, respectively. After bonding and 500 thermocycles, half of specimens of each subgroup (n=8), tested after thermocycling and 24.. Read More»
