From: Evoked and spontaneous pain assessment during tooth pulp injury
Mouse Grimace Scale following pulp exposure. (A) Before injury mice have low or no score for each of the action units, while after injury (B) prominent presence of the action units, as labeled on the example images from the same mouse. (C) We found a significant increase in the Mouse Grimace Score at all post-exposure time points captured, n = 6/treatment, Dental Pulp Injury (blue) and sham (red). Square shapes with black borders and lighter data points indicate females. *Indicates p < 0.0001 within the pulp exposed group before vs. after (Dunnett’s post-hoc).
