Comparative Evaluation Of Surface Roughness Of Two Commercially Available Glass Ionomer Cement Before And After Immersion In Fizzy Drinks - An In Vitro Study

Introduction: Glass ionomer cement is a restorative material used in dentistry. It is used for its good biocompatibility and fluoride releasing properties. The aim of the study is to assess the surface roughness of two different brands of glass ionomer cement before and after immersion in fizzy drinks. Materials and Methods: Two different brands of GIC collected (D-tech and Pyrax). Samples were prepared with the help of moulds. Around 6 samples were prepared in their own group. The prepared samples were trimmed to 2.5 mm using a polishing kit. Ra, Rq, Rz were calculated for pre and post immersion using a stylus profilometer- Mitutoyo SJ310, 2μm tip/60 degree angle. The immersion medium used is coca cola, 7 up and distilled water). Results: On analysing the findings, Ra, Rq and Rz value of both types of GIC used got reduced after immersion in Coca cola, 7 up and distilled water. Ra and Rq values of all the six samples for each group before immersion remain constant and Ra and Rq values of all the six samples of each group after immersion also remain constant. But the Rz values of both the brands of GIC showed variations. Independent sample t test was done. P value is 0.097, considered to be statistically significant. Conclusion: Our present study concludes that surface roughness of GIC decreases after immersion in fizzy drinks.
