The German pioneer in electro-acupuncture, Dr. Voll, established a relation between dental problems and the state of organs and body parts. This Small Chart gives a concise summary of his research. On one side the organs, nerves, glands, joints and bones corresponding to each tooth are presented in a large circular table. The back explains the theory and applications of Voll's work, and illustrates the correspondence between the teeth and the spinal column.
