Mechanical Properties of High-Viscosity Glass Ionomer Cement and Nanoparticle Glass Carbomer

Table 2

Knoop hardness means and standard deviation of the restorative materials.

Restorative material	Knoop hardness
Glass ionomer cement	24.32 (1.21)^a
Glass carbomer	20.80 (1.61)^b

Different lowercase letters indicate statistical difference between the restorative materials.
