Corrosive Effect of Probiotic And Isotonic Drinks on Dental Archwires

Abstract

The aim of this in vitro study was to investigate the effect of probiotic and isotonic drinks on chromium (Cr) and nickel (Ni) release from dental archwires. The conventional stainless steel dental archwires were used in this study, with 0.8 cm diameter, and 5 cm long from each sample. Total samples are 54 pieces dental archwires. The samples then divided into two major groups: (1) the probiotic (T1); and (2) isotonic (T2) drinks. Each major group consist three subgroups, such as: for the T1: (1) T1,1: as a negative control group (samples were immersed in saline solution); (2) T1,2: as a positive control group (samples were 1% lactic acid); (3) T1,3: as a treatment group (samples were immersed in normal saline + probiotic drink); and for the T2: (1) T2,1: as a negative control group (samples were immersed in saline solution); (2) T2,2: as a positive control group (samples were immersed in 1% lactic acid); (3) T2,3: as a treatment group (samples were immersed in normal saline + isotonic drink). After the immersion testing, there was a significance difference in Cr and Ni release from dental archwires between the subgroup of treatments from both probiotic and isotonic drinks (Kruskal-Wallis test followed by Mann-Whitney test; P > 0.05). In conclusion, the present study demonstrated that both probiotic and isotonic drinks induced the releasing of Cr and Ni from dental archwires.
