Cytotoxic and genotoxic potential of the type I photoinitiators BAPO and TPO on human oral keratinocytes and V79 fibroblasts

The initiator is an important component of light-curing dental adhesives and resin composites. Camphorquinone (CQ) is the mostly used photoinitiator for photo-polymerizable dental resinous materials. CQ requires an accelerator, such as a tertiary amine, to promote an efficient polymerization process [1]. However, despite its clinical acceptance and broad application, the CQ/amine system has its limitations. It can impair the esthetic appearance of resin restorations due to its yellow colour. It also may cause adverse interactions with acidic monomers, which may decrease the stability of the dental materials and affect the polymerization reactivity and the adhesion properties [2 –6].
