\u2022 Polyacrylic acid in the form co-polymer with itaconic acid & malice acid
\u2022 Tartaric acid: increase handling characteristic and increase working time
\u2022 Water: medium of reaction and hydrates the reaction products<\/p>\n<\/div>\n<\/div>\n\n\n\n
Type I 4-5 minutes
Type II 7 minutes<\/p>\n\n\n\n
Compressive strength- 150mpa
Tensile strength- 6.6mpa
Hardness- 49KHN
Solubility: Initial solubility is high due to leaching of intermediate products
Adhesion: It bonds chemically to the tooth structure
Aesthetic: GIC is tooth coloured material, but are inferior to composite. They lack translucency and rough texture.<\/p>\n\n\n\n
\u2022 Inherent adhesion to the tooth surface
\u2022 Good marginal seal
\u2022 Anticariogenic property
\u2022 Biocompatibility
