VALUTAZIONE DELLA CITOTOSSICITA’ DEI MATERIALI DENTALI DA IMPRONTA

THE AIM OF THIS STUDY WAS TO ASSESS THE CYTOTOXICITY OF SOME IMPRESSION MATERIALS AND OF THEIR COMPONENTS (PASTE AND CATALYST). THE FOLLOWING MATERIALS WERE TESTED: ELITE H-D + PUTTY SOFT NORMAL SETTING, ELITE H-D + LIGHT BODY NORMAL SETTING, ELITE H-D+ MAXI TRAY MATERIALS; EXPRESS PUTTY, FIRMER SET, EXPRESS FAST SET, LIGHT BODY, PERMADYNE PENTA L, IMPREGUM PENTA AND AQUASIL FS DECA MONOPHASE.THEI CYTOTOXIC EFFECTS WERE STUDIED BY INDIRECT AND DIRECT TESTING ACCORDING TO ISO 10993-PART 5. DIRECT TESTS WERE PERFORMED BY PLACING IMPRESSION MATERIALS IN THE CENTER OF PETRI DISHES CONTAINIG HUMAN GINGIVAL FIBROBLASTS.
