Figure 2 Changes in dental pulp sensations secondary to anesthesia with time in photobiomodulation group (G1A 635-nm, G1B 808-nm) in comparison to control (sham laser G2 – A and B). Data are presented as box-whiskers plot (median, lower-upper quartiles [Q1-Q]) of the dental pulp excitability level before and secondary to anesthesia and photobiomodulation (PBM). Horizontal lines indicate the differences between the groups. Statistical significance was defined at a P value <0.05 and presented as *.
