Dataset for: Bond strength of injectable composites under different enamel treatments and bonding strategies

Raw microshear bond strength data from an in vitro study evaluating three injectable resin composites (Beautifil Injectable X SL, Estelite Flow Quick, and G-aenial Universal Flo) and one conventional composite (Filtek Supreme XT) bonded to enamel under two surface conditions (intact enamel vs. enamel grinding with a diamond bur) and two bonding strategies, etch-and-rinse vs. self-etch mode, with the same universal adhesive (Scotchbond Universal). The dataset comprises 160 individual specimens in a full factorial design (4 × 2 × 2), with 10 specimens per group. Bond strength values are reported in megapascals (MPa) for each specimen. The file contains the complete raw dataset. A README with the variable dictionary, group definitions and testing conditions is included.
