This study evaluated the effect of polishing after one day storage in artificial saliva on the marginal gap formation around fillings using conventional glass ionomer (Fuji II) and resin-modified glass ionomer (Fuji II LC). Standardized cylindrical cavities were prepared on the grounded flatg proximal surface of 40 freshly extracted non carious premolars, 20 teeth were restored with Fuji II and other 20 with Fuji II LC following the manufacturer’s instructions. The groups with delayed polishing were restored I day earlier, stored in artificial saliva at 37°C and finished polished on the same day as the groups with immediate polishing. The results showed a gap of 21 to 60 mm for resin modified and conventional glass ionomer respectively, when polished immediately after the setting procedure. In contrast, a marginal gap width of 9 to 19 mm was measured when the specimens were polished after one-day storage. Hygroscopic expansion, bond strength and flexural strength play important roles in reducing the marginal gap in tooth cavities filled with two types of glass ionomer restorative materials.
