- PublicationOpen AccessA comparison of the shear bond strength of a resin cement and two orthodontic resin adhesive systems(E.H Angle Education and Research, Inc., 2005-01-01) Vicente, Ascensión; Bravo, Luis Alberto; Romero Maroto, Martín; Ortiz Ruiz, Antonio José; Canteras Jordana, Manuel; Dermatología, Estomatología, Radiología y Medicina FísicaThe object of this study was to compare the shear bond strength and the quantity of adhesive remaining on the tooth after the debonding of brackets bonded with two light-cured orthodontic resin adhesive systems (Transbond XT and Light-Bond) and a dual-cured resin cement (RelyX Unicem). Seventy-five premolars were divided into three groups. In each group, brackets were bonded with one of the adhesives according to the manufacturer's instructions. Shear bond strength was measured using a universal test machine at a crosshead speed of one mm/min, and adhesive remnant was quantified using image analysis equipment. Our results showed that the resin cement produced significantly lower bond strength than the two orthodontic resin adhesive systems. It was also observed that the bond strength produced by Light-Bond was significantly greater than that of Transbond XT. RelyX left significantly less remnant adhesive than Transbond XT and Light-Bond. Between the two orthodontic systems, Light-Bond left significantly less adhesive on the tooth than Transbond XT.
