Aims and Objectives: To evaluate the tensile bond strength (TBS) of G-Bond (GB, self-etching adhesive) to dentin following the application of CPP-ACP (Tooth Mousse/TM), with and widiout prior etching.
Materials and Method: Freshly extracted forty five permanent molars were collected for the study. All the teeth were ground and polished to expose the flat dentinal surface. The teeth were embedded in the resin in separate molds and were divided into three equal groups of fifteen samples each Group 1: Samples treated with Tooth Mousse for 60 min daily for 7 days and then restored with GB and composite (Filtek Z350, 3M ESPE). Group 2: Samples treated with Tooth Mousse and etched with phosphoric acid prior to restoration with GB and composite. Group3: Samples restored with GB and composite. A split brass mold was placed over the predesigned location and with help of the plasma coated instrument, composite resin was placed. Tensile loading was done using Universal Testing Machine.
Conclusion: TBS of GB was not significantly reduced after CPP-ACP application, but after prior etching the CPP-ACP specimens, the bond strength of GB was significantly reduced.
