Abstract

Aim of the study

To determine the solubility of nanohybrid (NH) composite resins when immersed in saliva substitute and distilled water.

Materials and methods

A total of 60 disc-shaped samples (n = 30) were prepared in teflon molds of diameter 10 mm × 2 mm thickness from two NH composite resins. They were light-cured following which the samples were removed and weighed three times using a digital balance. Samples were then immersed in test solutions, i.e., 100 mL of distilled water and saliva substitute each stored for 24 hours and 7, 14, 21, and 28 days in an incubator at 37°C at 100% humidity. At the time intervals mentioned, the samples were removed from the incubator, washed with distilled water, blotted dry, and weighed. Samples were again immersed in fresh test solutions. Difference in preweight and postweight of samples was calculated and data were analyzed using appropriate test by testing normality. A p-value < 0.05 was considered to be significant.

Results

The results were analyzed using one-way analysis of variance (ANOVA). As observed from the baseline weight to the 28th day weight, there was a loss of weight of the samples in all the groups except NH composite resin (Flash) in distilled water.

Conclusion

From the results of the study, it was observed that there was no statistically significant difference in weight, with respect to the solubility of the two NH composite resins and the two solutions tested. Clinical significance of the study is that the NH composite resin that shows lesser solubility can be the choice for an esthetic restorative material in patients for long-term results.
