Popis: Dental pulp is built by proteins that have various roles in the biological process of pulp, such as structural protein, regulation protein, and catalytic protein. L-arginine, an amino acid and one of the building blocks of proteins, regulates pro-inflammatory and anti-inflammatory activity. Therefore, L-arginine-based culture has potential to promote dental pulp regeneration. This study aimed to investigate the potential of L-arginine-based culture in improving the viability of human dental pulp stem cells (hDPSCs). We evaluated the viability of hDPSCs in culture media supplemented with different concentrations of L-arginine amino acid (250, 300, 350, and 400 μmol/L) and Dulbecco's Modified Eagle Medium plus fetal bovine serum 10% (control) using a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay after 24-h incubation time. Statistical analysis was conducted using a one-way analysis of variance and post hoc least significant difference test. In qualitative analysis, the 4´, 6-diamidino-2-phenylindole staining method was used. The evaluation has shown a significant result when 250, 300, and 350 μmol/L concentration of L-arginine amino acid culture media compared with control, and 400 μmol/L has the best result and was not significantly different with control toward viability of hDPSCs.
