Modelling gingival re-epithelialization. (a) Representative sigmoidal curve obtained from the enumeration of epithelial cells infiltrating into the scratched area over time. Modified Gompertz function for sigmoidal curve fitting consisting of three parameters: the inflection point (λ, in minutes), the repair rate (μm, in cells minute−1) and the maximum number of cells (A, in cells). (b) Spearman Rank Correlation coefficient to assess the relation between the A parameter and the relative scratch closure. All values were normalized against the non-treated control.
