Abstract:
Objective :To investigate the cytotoxicity of slightly acidic electrolyzed water (SAEW) on oral keratinocyte monolayers.
Methods:TR146 human keratinocyte monolayers were exposed to SAEW pretreated with bovine serum albumin（BSA）. It was divided into 4 groups, BSA 0 mg/mL (SAEW stock solutsion), BSA 0.5 mg/mL, BSA 1 mg/mL and BSA 2 mg/mL. The relative growth rate (RGR) was measured using a CCK-8 assay at 1 min, 5 min, 15 min, 30 min and 1 h, and the survival rate was measured using a Trypan Blue exclusion assay at 1 h.
Results:The CCK-8 assay showed significantly different OD values in the SAEW and negative control groups at different times and FAC concentrations (P<0.05). With increasing FAC concentrations and observation times, the RGR in the SAEW group decreased, and the SAEW showed moderate to severe cytotoxic effects. The OD values in the BSA (0.5~2 mg/mL)-pretreated SAEW and negative control groups were not significantly different at different times or FAC concentrations (P > 0.05); the RGRs of the BSA-pretreated SAEW group all approached 100%, and no cytotoxic effects were observed in the BSA-pretreated SAEW group. The Trypan Blue exclusion assay showed significantly different survival rates in the SAEW and negative control groups at different FAC concentrations (P < 0.05). As the FAC concentration increased, the survival rate in the SAEW group decreased, and SAEW showed moderate to severe cytotoxic effects. The survival rates in the BSA-pretreated SAEW and negative control groups were not significantly different at different FAC concentrations (P > 0.05); the survival rates in the BSA-pretreated SAEW group all approached 100%, and no cytotoxic effects were observed.
Conclusion:SAEW showed no adverse effects on the viability of dental oral keratinocyte monolayers in vitro in the presence of BSA at concentrations equivalent to that of protein in saliva.
