ABSTRACT
Objective:
To compare the marginal microleakage of various d ental filling materials.Methods:
45 extracted caries-free teeth were divided into 3 groups with 15 in each. The teeth were cleaned and standard cavity of I and V were prepared and filled with silver amalgm(group 1), GI-1 g lass ion cement(group 2) and glassionomer cement FX(group 3) respectively. The s amples were kept at 37 ℃ for 1-3 months.Dye penetration test was used to obser ve the marginal microleakage.The space between the restorations and tooth struct ure was measured under an electronmicroscope.Results:
Dye penetr ation was observed in all the three groups.The teeth with grade 1, 2 and 3 penet ration in group 1 were 11,4 and 0, in group 2 were 1,4 and 10,in group 3 were 2, 8 and 5(P
