Conference Paper Description

A total 70 samples Disks shape were designed to testes. Gingival fibroblasts of human (Manassas, VA, USA) and MTT assay were applied to measurement of toxic substances or biocompatibility test after washing in (10 and 30min) with (Isopropyl alcohol and Ethyl alcohol). Non washing as a control group in (distilled water). The purpose of the study evaluation the effect of two different types of the alcohols on surface deformation, hardness, and cell viability, of 3D-printed dental resin materials that use to denture base. The mean and standard deviation of shore D hardness were recorded for 10min (CTR, IPA, ETOH) (82.59±2.04,79.21±2.39,76.16±2.37), for 30min (82.59±2.04,76.16±2.57,75.99±2.28). The cell viability highest mean recorded in30min (81.24%,79.05%) with (IPA, ETOH). and (CTR)lowest mean (20.67%). In this study appear significant effect the washing solutions and time on biocompatibility as well as no significant effect on surface texture and hardness of 3d resin materials.
