| Summary: | Objectives: To investigate the effect of acidic solution on surface roughness and microleakage of tooth-colored restorative
materials.
Materials and Methods: A 160 box-shaped cavities were prepared on the buccal surfaces of 160 human molars, and assigned
to four groups: Group A restored with Ketac™ Molar Easymix, Group B with Fuji II™ LC, Group C with Ketac™N100, and
Group D with Filtek™ Z250, and subdivided into study and control groups (n = 20). Study groups were immersed in lemon
juice (pH = 2.79) for 24 h, whilst controlgroups in deionized distilled water. All samples were immersed in 2% methylene blue
dye, sectioned into two equal halves for surface roughness, and microleakage tests. Data were analyzed using Mann–Whitney
and Kruskal–Wallis tests at P < 0.05.
Results: There was a significant difference in surface roughness of Ketac™ Molar, Fuji II™LC, and Ketac™N100. No significant
difference was found in microleakage of Ketac™ Molar and Fuji II™LC; however, there were significant differences in the
gingival margin of Ketac™N100, and the occlusal margin of Filtek™Z250.
Conclusions: All glass ionomer cements were eroded after exposure to the acidic drink. Filtek™ Z250 and Ketac™ Molar
Easymix showed more microleakage. All materials showed more microleakage at the gingival margins. |
