A comparative evaluation of resin- and varnish-based surface protective agents on glass ionomer cement - a spectrophotometric analysis.

ABSTRACT: Objectives: To evaluate and compare the effectiveness of resin- and varnish-based surface protective agents on Glass Ionomer Cement (GIC). The different surface protective agents used were: Vaseline^®, GC Fuji VARNISH™ (varnish), G-Coat Plus™ (resin) and EQUIA^® Coat (resin). Method: Thirty-six identical specimens of GIC were made. Six specimens were used in preparation of standard solution and remaining thirty were divided into five groups with six specimens in each group. Each test specimen was coated with one of the surface protecting agent except for the control group. The specimens were immersed separately into 1 ml of 0.05% methylene blue solution for 24 h and then rinsed with deionised water and further immersed into tubes containing 1 ml of 65% nit
