Buceal cavities were prepared in vivo on 22 contralateral tooth pairs. The cavities and the surrounding enamel were either etched or cleaned, with a surface-active solzition (the control). The cavities were filled with Concise Enamel Bond and composite or left unrestored. The teeth were extracted, imanertiately after treatment. Treated surfaces or the inner surface of the restorations were studied in the scanning electron microscope (SEM). An "in-pair" evaluation of the results of 320 photographs was done. The etched axial wall had a smooth surface with widened and patent denlinal tubule apertures. The corresponding inner resin surfaces were irregular, sporadically showing tags of varying length corresponding to the denlinal tubules and alternating with pits of varying size. Etching for 15 seconds or two minutes gave no apparent difference in appearance of enamel, denlin, and inner surface of the restoration.
