Evaluation of Resins for Stereolithographic 3D-Printed Surgical Guides: The Response of L929 Cells and Human Gingival Fibroblasts

Figure 7

Response of L929 and gingival fibroblasts activity to printed and postcured Clear and Dental SG resin specimens in a direct monolayer culture model. L929 cells ((a), (c), and (e)) and gingival fibroblasts ((b), (d), and (f)) were seeded and cultured on printed and postcured Clear or Dental SG resin specimens. Then cells were subjected to MTT ((a), (b)) and resazurin-based toxicity assays ((c), (d)). Furthermore MTT staining was performed ((e), (f)). Data are given as mean standard deviation and are presented relative to the untreated control (W/O). Four independent experiments were performed. , resin versus W/O; the color of indicates the specific resin.
