An in vitro study on the depth of etched enamel using the acid etch technique at different time durations (15, 60 an 90 secs.)
Each of the five samples of polished newly extracted human premolars were sectioned into 3 equal parts, giving a total of 15 specimen. The 3 parts of each tooth sample were treated or etched at 15, 60 and 90 secs. respectively, using 50% Phosphoric acid. The depth of etched enamel rods were measured...
