Illustration of the scoring system (a) macroscopic view; score 0: no infiltration. “A” represents the enamel wall, “B” the pulpal wall, and “C” the cement wall. (b) microscopic view; score 1: infiltration (here: enamel infiltration) inferior to the half of the wall length. (c) microscopic view; score 2: infiltration (here: cement infiltration) superior to the half of the wall length, without penetrating the pulpal wall. (d) microscopic view; score 3: infiltration (here: cement infiltration) with pulpal infiltration.
