| Objectives This study compared the microhardness of inactive proximal lesions after different remineralizing treatments, and investigated the resistance of treated lesions to a further demineralization challenge. Materials and Methods In this in-vitro study, 30 human molars with inactive proximal lesions were selected and randomly divided into three groups of 10. In group 1, the lesions were treated with a resin infiltrant (Icon). In group 2, the surface was conditioned by an Er: YAG laser before resin infiltration. The specimens in group 3 were remineralized by the bioactive glass. The specimens were kept in artificial saliva for 1 week and then immersed in a demineralization solution for 8 weeks. Microhardness was measured at baseline (T0), after remineralization (T1), and after exposure to the demineralization (T2) solution. Hardness values were compared between the treatment intervals in each group. The alterations in microhardness after the treatment and the demineralization challenge (ΔVHN) were calculated and compared among the groups. Results In all groups, microhardness after demineralization was significantly lower than other intervals, but no significant difference was found between the T0 and T1 values (P> 0.05). The alterations in microhardness between T1 and T0 (ΔVHNT1-T0) and between T2 and T1 (ΔVHNT2-T1) were not significantly different among the groups. Conclusions Pretreatment by Er: YAG laser before resin infiltration was more effective than other treatments in enhancing microhardness and protecting the tooth against the acidic challenge. However, the difference between groups did not reach statistical significance … |
