Figure 1: Technique used to build resin specimens for micro-shear testing in GECA and GECAT group. (a) Glass ionomer cement was inserted into acrylic artificial cavities; (b) grinding the glass ionomer cement surface with cylindrical diamond point; (c) acid etching with 37% phosphoric acid in all glass ionomer cement surface; (d) starch tube stabilized in position with a gingival barrier; (e) adhesive application within each starch tube followed by insertion of the high-flow resin composite; (f) starch tubes softened by the moisture were easily removed with a manual instrument
