Biological Studies of the Fungi of the Human Mouth (Classic Reprint)
(Excerpt from Biological Studies of the Fungi of the Human...)
Excerpt from Biological Studies of the Fungi of the Human Mouth I always keep on hand sections of potato and egg, also tubes of gelatine, agar-agar, and blood serum, and when in my practice particularly good material, or anything uncommon presents itself, a portion of it is at once transferred to these different culture media, so that it is pretty sure to develop in one of them, at least. For example, I have several times met with a fungus in the human mouth which produces a yellowish coloring matter, and which absolutely refuses to grow on anything which I have tried, except potato. Bv use of the methods described I have isolated twenty-two dif ferent fungi from the secretions or deposits of the human mouth, and have endeavored to determine, as far as possible, their separate peculiarities of growth, physiological action, etc. It will, however, at once suggest itself to every one, that a thorough study of twenty two different fungi involves an enormous amount of labor, and might constitute almost a life task for one experimenter. The task is, moreover, rendered still more difficult by reason of the fact that many of these fungi show differences of action when cultivated in different media, rendering the number of experiments necessary to come to a definite conclusion doubly great. I shall, therefore, not attempt to present an exhaustive treatment of the subject, but rather an introduction, heping, at the same time, to establish some points which may be of use in bringing about a clearer understanding of the factors involved in the production of dental caries.

Education
Miller's education began in the county public school; but in 1865 his parents removed to Newark, Ohio, where he graduated from the high school in 1871. In the same year, he entered the University of Michigan at Ann Arbor and received the degree of A. B. in 1875. He then took special courses in chemistry, mathematics, and physics at the University of Edinburgh, and in 1876 entered upon further study along these lines at the University of Berlin. Overwork resulted in a nervous breakdown in 1877, but during his convalescence, he mingled in the social life of the American colony in Berlin and collaborated in some chemical researches with F. P. Abbot, a pioneer American dentist in Germany. Miller decided to adopt dentistry as his profession. He served a few months as a student assistant to Abbot, then, late in 1877, entered the Pennsylvania College of Dental Surgery, which became the Dental Department of the University of Pennsylvania in 1878 and graduated Miller with the degree of D. D. S. in 1879. In 1887, he graduated with the degree of M. D. from the medical school of the University of Berlin with the predicate magna cum laude.
Career
Miller began the practice of dentistry with the father of his wife, at the same time continuing his studies at the University of Berlin. From the beginning of his professional career to the time of his death, Miller was especially interested in bacteriology and chemistry as related to dental and oral diseases. The first of his many articles on micro-organisms in the etiology of dental caries appeared in German in 1881 and in English in 1882. In 1884, he was appointed a professor of operative dentistry in the newly organized Dental Institute of the University of Berlin.
In his laboratory experiments, Miller produced caries in extracted human teeth by means of bacteria from the mouth and demonstrated that tooth tissue is destroyed by fermentative acids formed by these micro-organisms. This is now generally accepted as the basic truth of the "chemicoparasitic theory"; but neither Miller nor his followers claimed that this theory could explain all the phenomena of dental caries. Miller's researches and writings also relate to various other subjects, such as the use of antiseptics in dentistry, diseased teeth and oral tissues as foci of infection, and the etiology of dental erosion and abrasion. His practice was confined to Berlin; but such was his loyalty to his native land that he declined to become a naturalized citizen of Germany. In 1907, he accepted the position of dean of the Dental College of the University of Michigan, his alma mater. Efforts were made to have him remain in Berlin, a wealthy merchant even offering to build, equip, and support a research laboratory for him in that city; but he severed his connection with the University there and brought his family to the United States, expecting to begin his duties at Ann Arbor in October 1907. In the summer of that year, however, while on a visit with his family to relatives in Alexandria, Ohio, near the place of his birth, he was stricken with appendicitis and died after an operation at the City Hospital of Newark, Ohio. He was survived by his wife and their three children, one son and two daughters.
Achievements
-
In 1894, Miller was made a professor extraordinary on the medical faculty of the same university, an honor rarely conferred upon a foreigner and never before upon a dentist, and about the same time, he became a state examiner for dentistry in Berlin. His elevation to these coveted positions at first aroused much opposition from German dentists, some of whom repeatedly petitioned the minister of education to give the offices to Germans; but this opposition was soon overcome, and Miller was recognized everywhere as one of the leading dental authorities and bacteriologists of his day. As a practitioner of dentistry, he stood second to none in Berlin, the Empress Augusta and other members of the imperial family being included among his many distinguished patients, while in 1906 the Emperor in a personal letter appointed him a privy medical counselor. He served as president of the National Dental Association of Germany, the Association of Dental Faculties of that nation, the American Dental Society of Europe, and the Federation Dentaire Internationale. He was also an honorary member of some forty dental societies in America and abroad. Miller published more than a hundred articles in professional journals. The majority were in German, while some were in English, but many of the former were translated into English. In America, most of his contributions to dentistry appeared in the Dental Cosmos and the Independent Practitioner. He also published two extensive works in book form, the more notable of which is Die Mikro-organismen der Mundhuhle (1889 and 1892), translated into English as The Micro-organisms of the Human Mouth (1890). This was followed by his Lehrbuch der Conservirenden Zahnheilkunde (1896 and 1898). In 1915, a life-size bronze statue of him was unveiled on the campus of the Ohio State University at Columbus.
