Due to the strong correlation between genotoxicity and carcinogenesis, it is necessary to clarify the potential genotoxic effects of titanium dental implant systems. As most dental materials release small amounts of several elements into the oral cavity, proper regulations have to guarantee that the concern from genotoxicity/mutagenicity of dental materials is annulated or at the lowest possible level. Thus, further biocompatibility records are needed in order to evaluate the comprehensive risks of these compounds. In a view of the above-mentioned data, the aim of this in vivo study is to evaluate genotoxic and cytotoxic potential of implants and gingiva formers from two different implant systems in gingival epithelial cells. Exfoliated gingival cells will be taken from 80 participants before and after 90 days of dental implant insertion, and 21 days following gingiva former placement. DNA damage will be analyzed using the micronucleus test. Tested dental implants will be Ankylos and Dentium, with corresponding gingival former.
