Evaluation of Cytotoxicity of different Universal Bonds using the Xcelligence System

Abstract

Objectives: The purpose of this study was to explore the cytotoxic effects of five different universal bonding agents on mouse fibroblast cell lines (L929).Materials and Methods: Five different widely used universal adhesive systems were chosen that have different contents, pH levels, and polymerization methods. A real-time cell analyzer (RT-CES, xCELLigence; Roche Applied Science, Germany, and ACEA Biosciences, USA) was used for cytotoxic evaluation of light-cured polymerized G-Premio Bond (GC Europe, Belgium), Prime&Bond Universal (Dentsply Sirona, USA), Universal Bond Quick (Kuraray, USA), Single Bond Universal (3M ESPE, USA) and self-cured polymerized Tokuyama Universal Bond (Tokuyama, USA) experimental groups. L929 were cultured in Dulbecco’s modified Eagle’s medium and supplemented with 10% fetal bovine serum and 1 % antibiotics. The assay was performed E-plate-16 and monitored every 15 min for 72 h. Statistical analysis was performed using ANOVA and Tukey’s posthoc tests.Results: All tested universal adhesive systems showed a statistically significant difference in cytotoxicity values in different periods (p<0.05). Among the groups compared, G-Premio Bond showed the least cytotoxic effect; and Tokuyama Universal Bond showed the most cytotoxic effect. Different times of all universal adhesive systems significantly increased the count of viable cells compared to the control group (p<0.05).Conclusions: In dentistry, universal adhesive systems can be observed cytotoxic effects to live cells. The evaluation of cytotoxicity with xCELLigence device is a reliable method and should be supported by new studies on this subject.
