ABSTRACT
AIMS:
The aim of the present study was to evaluate the microleakage among conventional, resin modified glass ionomer cements (GIC), and compomer cements in primary teeth. MATERIALS ANDMETHODS:
Forty-five over retained non carious primary molars beyond exfoliation time were collected and randomly divided into three groups (n = 15). Group A GC Fuji II; Group B Vitremer; Group C Compoglass F. A standard Class V cavity was prepared on the buccal surface of each tooth with no mechanical retention and restored accordingly. Then all the samples were subjected to thermocycling for 250 cycles at different temperatures and covered with nail varnish. Later, samples were immersed in 0.5% methylene blue dye for 24 h. Teeth were sectioned buccolingually through the center of the restoration and studied under a stereomicroscope for dye penetration. Data obtained were analyzed using Kruskal-Wallis ANOVA and Mann-Whitney U-test.RESULTS:
Samples restored with vitremer showed comparatively higher microleakage than the samples in other groups. However, overall there were no significant difference between the microleakage scores of the samples in all three groups (P > 0.05).CONCLUSION:
It can be concluded that none of the three GICs was free from microleakage. Hence, further research is required to compare microleakage of the newer material.
