The influence of incorporation of hydroxyapatite/collagen nanocomposite into glass ionomer cement on surface roughness, microhardness, and fluoride-ion release potential.

ABSTRACT:

Objective

To investigate the effect of incorporation of 5 and 10 weight% of hydroxyapatite /collagen (HA/Col) nanocomposite with different ratios (50:50) and (70:30) to conventional glass ionomer cement (C-GIC) on surface roughness, microhardness, and fluoride-ion release.

Materials and methods

Seventy-five specimens were prepared using split Teflon mold (5 mm in diameter and 2 mm in thickness) and were randomly assigned to 5 different groups. Group I: control group of C-GIC, Group II: GIC modified with 5% HA/Col (50:50), Group III: GIC modified with 5% HA/Col (70:30), Group IV: GIC modified with 10% HA/Col (50:50), Group V: GIC modified with 10% HA/Col (70:30). The specimens were kept in deionized (DI) water and incubated at 37 °C.The DI water in each container was changed
