Cytotoxicity of a silorane-based dental composite on human gingival fibroblasts

Figure 1 Histogram of cell viability. A: Cell viability of fibroblast cultured directly on unpolished samples (UnP), polished samples (P: finished surface using polishing discs) and control (CTRL); B: Cell viability of fibroblasts in CTRL, polished samples at 1 wk (P 1 w), unpolished samples at 1 wk (UnP 1 w), polished samples at 3 wk (P 3 w), unpolished samples at 3 wk (UnP 3 w); ^aP < 0.05 vs CTRL; ^cP < 0.05 P 1 w vs P 3 w.
