Abstract

Objective: To compare the weight change of two commercially available variants of each; conventional GIC, RMGIC & resin composite when stored at 100% humidity at mouth temperature (37˚C).

Materials and Methods:The samples of Fiji IX, Chemfil Rock, and Fuji plus were allowed to set for 15 minutes. Light cured Fuji II LC were polymerised for 20 seconds, kept in an incubator for 60 minutes and for storage in deionized H2O at temperature of 37°C as per instructions of the company. Weight changes were for all the sample were carried out using an analytical balance
at two intervals; Pre and post immersion of samples in the said medium. The weight changes were recorded at 24 hours, 4 days, 1 week, 2 weeks, 3 weeks, and 4 weeks. Surface water was blotted post immersion for every sample and weighed. For all samples the average and standard deviation evaluated & t test stats to see any important differences.

Results:At 24 hours, on an average the maximum wt% change was noted for self-cure Fuji Plus (3.350 ± 0.0034%) this weight change was significantly higher when p value was considered significant at 0.05. At 4 weeks the average wt% change remained highest for self-cured rein modified glass ionomer (4.250 ± 0.0049%).

Conclusion:RMGIC had maximum variation in weight when stored at 37˚C in deionized water as compared to conventional GIC and dental composite materials.
