GUSMAO, João Milton Rocha; PITHON, Matheus Melo; SANTOS, Rogerio Lacerda dos  and  ROMANOS, Maria Teresa Villele. In vitro evaluation of cytotoxicity of different brands of artificial teeth. Arq. Odontol. [online]. 2012, vol.48, n.3, pp. 120-124. ISSN 1516-0939.

Aim: The present study aimed to evaluate the cytotoxicity of different brands of stock acrylic teeth against fibroblast cells. Materials and Methods: For this experiment, the cell lineage used was the L929 from the American Type Culture Collection (ATCC, Rockville, MD, USA). The brands of stock teeth tested included: Artplus, Biolux, Biotone, Pop Dent, Vipi Dent, Orthosit Ivoclar, Biocler, and Trilux. Each group was placed in contact with the fibroblast cells for the periods of 24, 48, 72, and 168 hours. Control cells, as well as negative and positive controls, were used to compare the extremes. Results: The results showed cytotoxicity for all the groups tested in the time periods of 24, 48, and 72 hours during the experiment, which occurred in the Orthosit Ivoclar and Trilux groups even after the experiment had been conducted for 168 hours. Conclusion: The researched acrylic teeth developed cytotoxicity against the cells in vitro during the time periods of 24, 48, and 72 hours, while Ivoclar Vivodent and Trilux brands of teeth developed cytotoxicity against the tested cells during the time period of 168 hours.
