Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Summary</title> <sec id="sca21077-sec-0001" sec-type="section"> <p>The aim of the present <italic>in vitro</italic> study was the evaluation of a CPP‐ACP paste on preventing dentin/enamel erosion produced by a soft drink; Atomic Force Microscopy and Scanning Electron Microscopy were used. Eighty extracted human incisors free of caries were selected and divided into four groups (each divided in two subgroups); group 1a: intact dentin; group 1b: dentin + soft drink; group 2a: intact dentin + CCP‐ACP paste; group 2b: dentin + soft drink + CCP‐ACP paste; group 3a: intact enamel; group 3b: enamel + soft drink; group 4a: intact enamel + CCP‐ACP paste; group 4b: enamel + soft drink + CCP‐ACP paste. The CPP‐ACP paste was applied for 3 min at 0, 8, 24, and 36 h. The surface of each dentin/enamel specimen was imaged by AFM (<italic>R</italic><sub>rms</sub> values were registered) and SEM. A statistical significant difference was recorded between groups 1b (dentin + soft drink) and 2b (dentin + soft drink + CCP‐ACP paste) and between groups 3b (enamel + soft drink) and 4b (enamel + soft drink + CCP‐ACP paste), suggesting that treatment of the specimens with the CPP‐ACP paste had a protective effect on enamel demineralization, which was more evident for enamel specimens. Under the limitations of the present <italic>in vitro</italic> study, it can be concluded that the application of a CPP‐ACP paste is effective on preventing dentin/enamel erosion produced by a soft drink.
