[The cytotoxic effects of composite resin adhesive agents on gingival cell culture using the agar coating method]

Because the luting agent interfaces of restorations can approximate the periodontium, it is critical to determine the biocompatibility of luting agents. In this study, the cytotoxic potential of resin luting agents on cultures of gingival fibroblasts was evaluated for direct microscopic cytotoxicity. For light cured composite resin luting agents, the exposure time was found to be significant. To compare the chemically and light cured resins, fully cured microfill resin's cytotoxicity was equal to the chemically cured resin's cytotoxicity. The least cytotoxic effect was occurred with hybrid type composite resin while the profound effect with unpolymerized microfill resin.
