Abstract
abstract— In the in vitro experiments of the present study Class V Addent XV® fillings were inserted on buccal surfaces of 32 permanent human teeth. Lesions were produced by placing acidified gelatin around the fillings. In the corresponding in vivo experiments, caries was produced around similar fillings in 17 permanent teeth. In both series, sections of the teeth with the fillings in situ were studied by polarized light microscopy and microradiography. All teeth showed “outer lesions”, but the tendency to development of “cavity wall lesions” was negligible. A comparison with lesions produced previously in corresponding experiments with silver amalgam and silicate fillings has been done.
