title: In vitro assessment of the effect of Scotchbond on the marginal leakage of class II composite restorations in primary molars.
abstract: By means of dye penetration, the authors determined the microleakage at the interface of class II composite restorations in thirty-eight extracted or naturally exfoliated primary molars. Scotchbond was used as the bonding agent in half of the prepared cavities' dentin and enamel; the control group (B) used Concise bonding agent in the enamel only. The use of Scotchbond in class II cavities did not prevent marginal leakage under the conditions of this study.
