  1. G1: saline + repair, G2: saline + repair, G3: PDRN + repair, G4: PN + repair, G: Group, G1: normal, G2-4: DM, P < 0.05. One-way analysis of variance, followed by Bonferroni post hoc testing or Kruskal–Wallis analysis, followed by Mann–Whitney post hoc testing was used to analyze the values among the groups according to normality. The data of load to failure were presented as mean ± standard deviation Vs mean ± standard deviation (95% confidence intervals) and p values.
