Photographs of the left mandibular first molar (36) taken before the demineralization procedure and progression of the demineralization process as monitored by dental radiographs. Tooth 36 from the (a) buccal and (b) mesial surface. Note the aberrant root morphology and a ribbon of hypomineralized enamel extending circularly around the tooth crown and toward the cervical area. (c) Radiograph of tooth 36 taken 14 weeks after demineralization with the mild bone-decalcification solution Osteosoft®. Note incomplete decalcification with unusual mineralized tissue in the area of the pulp chamber (asterisk). (d) The process was successfully completed after additional overnight decalcification with a 1:1 mixture of Osteosoft® and Osteomoll® solution
