| Abstract | ||
| Aim of the study: To evaluate the efficacy of Beautifil-II LS giomer restorative material to inhibit enamel demineralization, as compared to conventional resin composite and glass ionomer restorative materials. Materials and methods: Nine premolar teeth were randomly divided into three groups (n=3): group A (Beautifil-II LS), group B (3M Filtek Z-250), and group C (GI FX-Ultra), Nine premolar teeth were restored with each material, subjected to pH-cycling, and analyzed via environmental scanning electron microscope coupled with energy dispersive X-ray (ESEM-EDX) analysis. The calcium to phosphate ratio (Ca/P) of the enamel surface was calculated according to the atom% of elements in EDX analysis in each stage. Results: According to the Ca/P recovery ratio, group A (Beautifil-II LS) showed higher results as compared to other tested restorative materials. Conclusion: Beautifil-II LS might represent a promising restorative material to decrease the incidence of recurrent caries around existing restorations.
