Figure 1 Illustrates the application of BCD solution on extracted teeth: (a) Preoperative carious tooth, (b) BCD applied, (c) preoperative radiographic image of caries, (d) radiographic image showing radiopaque extension of BCD, (e) radiograph after caries excavation, (f) soft caries removal by spoon excavator, (g) effective caries removal, (h,i) mesio-distal sectioned tooth surface with black arrow indicating no residual BCD and red arrow indicating the noncarious coronal dentin surface; (i) Clean tooth sections (16× magnification) prior to SEM analysis. BCD, bioactive caries detecting dye solution; SEM, scanning electron microscopy.
