Polarized light micrographs of morphological examples of the 4 groups of control and experimental teeth. a) Negative control N: Homogeneous surface zone, demineralized body of the lesion with no laminations; arrow with asterisk = surface zone, double arrow = body of the lesion. b) Positive control P: Homogeneous surface zone, smaller body of the lesion, detectable translucent zone; arrow with asterisk = surface zone, double arrow = body of the lesion. c) Experimental group D1: homogeneous surface zone, small band of the body of the lesion, detectable translucent zone arrow with asterisk = surface zone, double arrow = body of the lesion. d) Experimental group D2: Homogeneous surface zone, disappearing body of the lesion with laminations, broad translucent zone; dotted line with outlined arrow = laminated body of the lesion, arrow = laminations; double outlines arrow = translucent zone.
