MOESM1 of N-acetyl cysteine prevents pain and hypersensitivity of bleaching agents without affecting their aesthetic appeal; evidence from in vitro to animal studies and to human clinical trials

Additional file 1: Figure S1. NAC protects DPSCs and OSCCs from cell death induced by different concentrations of bleaching agents containing hydrogen peroxide. Figure S2. NAC protects DPSCs from growth inhibition after bleaching in rats. Figure S3. NAC protects the gingival cells from undergoing cell death in the presence of bleaching agents in rats.
