title: Microleakage along composite restorations in human premolars after treatment with different cleansing agents.
abstract: Cavities prepared on extracted human premolars wereeee treated with different cleansing agents and by different procedures. The cavities were filled with a composite restorative material and microleakage was assessed by recording the penetration of basic fuchsin dye. Only acid agents which removed the smeared layer, producing an etch pattern on the enamel cavity walls, were able to prevent microleakage.
