Figure 3

Box-and-whisker plots (100%) presenting infiltrated areas (in % of total enamel lesion extent) of Group 1. Boxes represent the interquartile range (IQR); the lines inside represent the median, while whiskers denote the maximum and minimum values. Subgroups correspond to bicuspids (n = 9) and molars (n = 10), and percentage of infiltrated areas differed significantly (*P = 0.034) between both tooth types. (Due to the missing infiltration capacity of the flowable composite resin, results of Group 2 are not depicted).
