Abstract

Doping of calcium phosphate glasses from the ternary system SiO₂-CaO-P²O₅, with transition metals ions makes them to acquire additional properties, of a prophylactic nature (anti-inflammatory, healing, antimicrobial). This paper presents the microbiological study performed of three glass compositions synthesized by sol-gel method, one doped with silver, the other doped with copper II, compared to a control sample, with the same compositional matrix, but not doped, in order to highlight their antimicrobial character and the determination of the minimum bactericidal dose of each type of glass on two strains of bacteria with high pathogenic potential.
