WebThe etch and sealant tag patterns were observed using SEM on all tooth surfaces after the 4 etch times. No differences in etch or tag patterns existed in the subgroups. Similar etch depths were seen on enamel surfaces after etching for 15, 30, and 60 sec (~10 t~m), but a greater increase in depth was observed after the 120-sec etching (50 ~m).
