Antibacterial activity of selected glass ionomer cements

Abstract

Antibacterial activity of glass ionomer cements has attracted the interest of scientists in recent years. Most authors, including us, carried out experiments using the agar diffusion method and demonstrated antibacterial activity of glass ionomer cements. Different antibacterial activity of glass ionomer cements, observed in our study and studies of other authors, depended on the evaluated cement, bacterial strain and period of evaluation.

Casein Phosphopeptide-Amorphous Calcium Phosphate Reduces Streptococcus mutans Biofilm Development on Glass Ionomer Cement and Disrupts Established Biofilms

“…mutans biofilms formed on a glass substratum after 16 h had a significantly higher biovolume than those formed on GIC using the same growth medium with similar flow conditions and shear forces ( Tables 2 and 3 ). This is consistent with recent studies that have indicated that GICs have an inherent inhibitory effect on bacterial growth, possibly due to the release of fluoride or other ions [42]. The incorporation of 3% CPP-ACP into the GIC further significantly inhibited S .…”

Antimicrobial properties of conventional restorative filling materials and advances in antimicrobial properties of composite resins and glass ionomer cements—A literature review

“…The most commonly used method is the agar diffusion test, due to its simplicity and cost-effectiveness [12]. In fact, the use of this method is very common, when it comes to testing of antimicrobial properties of restorative materials [1,11,12,22,23,25,[28][29][30]33,34,44,65,71,74,[76][77][78]84,87,103,104,111,118,122,144,146,152,170]. Measurement of the area of inhibition has been suggested in order to reduce any misinterpretation of results, due to this test's qualitative nature [25].…”

“…Considerable differences exist in the antibacterial properties of different materials and some variation may also be noted between different formulations of related materials. The antimicrobial properties of same materials varied as well when tested against different micro-organisms and strains, as well as after different aging times [18,[31][32][33][34].…”

“…These include amalgams [12,18,31], calcium hydroxide [31,35,36], polycarboxylate cement [31], composite resin [31], zinc oxide eugenol [31,[37][38][39], glass ionomer cement [27,33,34,37,[39][40][41][42][43][44]. xxx.e3…”

An Invitro Comparative Evaluation of Compressive Strength and Antibacterial Activity of Conventional GIC and Hydroxyapatite Reinforced GIC in Different Storage Media

“…Zalewska A conducted a study to evaluate antibacterial activity of different types of GIC {Fuji Triage (GC), Fuji IX (GC), Ketac Molar (3M ESPE) and Ketac Silver (3M ESPE)} against various cariogenic bacteria which includes Streptococcus mutans, Streptococcuss anguis, Streptococcuss alivarius and Lactobacillus casei and concluded that Fuji IX GIC showed potent antibacterial activity against Streptococcussanguis but with overall antibacterial activity Fuji triage showed most potent and Fuji IX showed least activity [20].…”
