Microleakage of three generically different fluoride-releasing liner/bases.
Three generically different fluoride-releasing materials that function as a liner or base were assessed for their microleakage performance on enamel and dentine. Group 1 (light-cured liner/base) showed much more leakage, but less bulk absorption of tracer, than Group 2 (traditional glass ionomer) or Group 3 (light-cured glass ionomer). The response of the three materials to tracer penetration was consistent with what is known about their chemistry. The Group 2 and 3 materials are probably the materials of choice at the caries-vulnerable margins, which are not easily visible for inspection.
