Buffering capacity and antibacterial properties among bioactive glass-containing orthodontic adhesives

This study was to evaluate the acid-buffering capacity and antibacterial properties of orthodontic adhesives containing bioactive glasses (BAGs) (45S5, 45S5F, S53P4), Hydroxyapatite, beta-tricalcium phosphate, Canasite. Fillers comprising 15 wt% glasses, HAp, β-TCP, Canasite incorporated with 55 silanated glass were added a mixture UDMA/TEGDMA. Acid-buffering tested by exposing disc-shaped samples each adhesive medium bacteria-produced acids, pH changes recorded at 24 48 h. Antibacterial assessed indirect testing polymerized direct immersing specimens in solutions S. mutans sanguinis. A significant buffering shown 45S5, 45S5F S53P4 BAG adhesives. The not all experimental Therefore, BAGs demonstrated but did show against
