Objectives To evaluate the effect of the addition of epigallocatechin-3-gallate EGCG on the antibacterial and physical properties of glass ionomer cement GIC. Methods A conventional GIC, Fuji IX, was used as a control. EGCG was incorporated into GIC at 0.1 ww and used as the experimental group. Chlorhexidine CHX was added into GIC at 1 ww as a positive control.

The hydration of cement generates heat due to the exothermic nature of the hydration process. Poor heat dissipation in mass concrete results in a temperature gradient between the inner core and the outer surface of the element. High temperature gradients generate tensile stresses that may exceed the tensile strength of concrete thus leading to thermal cracking.
