Abstract

The purpose of this study was to examine the in vitro remineralization of incipient caries lesions on teeth adjacent interproximally to teeth with Class II glass ionomer cement restorations. Sixty four extracted molars were selected and 1 x 5 mm artificial caries lesions were created at the interproximal contact point. One hundred micrometer sections were obtained at the caries sites, and polarized-light photomicrographs were obtained. The sections were covered with varnish, leaving only the external section site exposed, and were placed back into the original tooth. In another sixty-four molars, Class II cavities were prepared. Equal numbers of preparations were filled with Fuji IX GP, Vitremer, Ketac-Molar, or Z 250. These sixty-four teeth were mounted to have interproximal contact with the adjacent teeth containing the artificial caries lesions. Specimens were placed in closed environments of artificial saliva for one month. After thirty days, the same sections were photographed again under polarized light, and areas of the lesions were quantitated. Decrease in the size of caries lesions indicated the glass ionomers had significantly greater remineralization effects on adjacent caries than the nonfluoridated composite resin (ANOVA p < 0.05). There were no significant differences among the three glass ionomers tested.
