Aim of the Study: To observe the surface roughness and micro-hardness of different selected glass ionomer restorative materials. Materials and Methods: 30 discs of three different glass ionomer materials were packed according to their manufacturer instructions then tested for surface roughness and micro-hardness. Each material was divided into two subgroups which are, coated and non-coated discs. Results: Between the three different glass ionomer materials, Equia Fil Plus showed superior micro-hardness above the other glass ionomer materials. For surface roughness in general, the non-coated material showed lower mean surface roughness compared to the coated material. Conclusion: In this research project, we concluded that Equia fil Plus holds the highest micro-hardness results followed by Ketac Fil Plus, then SDI glass ionomer. The surface roughness testing showed that, in the subgroup of the coated materials, the SDI glass ionomer holds the lowest mean surface roughness value followed by Ketac Fil Plus then Equia Fil Plus. In the non-coated subgroup, Ketac Fil Plus showed the least value than the SDI then Equia Fil Plus.
