Purpose: The aim of this study was to determine biocompatibility of spongostan, merocell, and ventilation tube using agar diffusion and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide tests in cell culture and to evaluate the results in terms of clinical practices. Materials and Methods: The experimental procedures involved in this study were approved by the Animal Ethics Committee of Cumhuriyet University (B.30.2.CUM.0.01.00-50/4), and the study was conducted following accepted guidelines for the care and use of laboratory animals for research. The present study was supported by Cumhuriyet University Scientific Research Projects (CÜBAP) Project no T-408. L929 mouse fibroblast cell culture was used in the present study. In this study, indirect toxic effects of the leakage products from the materials were tested with the agar overlay test, and also direct toxic effects of leakage materials occurring at different time and leakage products from the materials were tested with the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide test. Results: As a result of evaluating the 21 days' leakage material of the ventilation tube a moderate (+2), 24 and 48 h of leakage material of the merocell low degree and 24-hour leakage material of the spongostan limited cytotoxicity were found. Conclusion: Many biomaterials cytotoxicity study were found in the literature as well as in our study shown by MTT and agar diffusion tests they were not toxic.
