Microhardness and Fluoride Release of Glass Ionomer Cement Modified with a Novel Al Complex to Enhance Its Antimicrobial Activity.

Objectives: To synthesize and characterize a novel Al complex with 2-(2-hydroxyphenyl)-1H-benzimidazole (HL) to be added to a restorative glass ionomer cement (GIC) to enhance its antimicrobial activities and to evaluate the Vickers microhardness (HV) and fluoride release (FR) of the modified GIC.

Materials And Methods: Al complex was synthesized by the addition of 1 mmol (0.210 g) of HL to 1 mmol (0.
