Charles C. Bass

Charles Cassidy Bass (January 29, 1875 – August 25 1975) was an American medical doctor and researcher on tropical medicine who made significant contributions to understanding malaria, hookworm, and other diseases. Later Bass studied the relationship between dental health and general well-being. Bass articulated and promoted the "Bass Technique of Toothbrushing" and developed improved means of flossing teeth, for which some refer to Bass as "The Father of Preventive Dentistry". He subsequently became a university administrator, serving as dean of the Tulane University School of Medicine, from 1922 to 1940.

Contributions to tropical medicine In 1911, Bass discovered an in vitro method of culturing the plasmodium organism responsible for malaria, a breakthrough in finding cures for the disease.

Around the same time, he succeeded in isolating the ova of the uncinaria, or hookworm, by isolating them in pure form from intestinal excreta. Additionally he contributed to the understanding of the vitamin diseases of beriberi and pellagra, being the first to recognize this disease in Louisiana. He simplified methods of diagnosing typhus, and discovered the cause and means of transmission of the poultry disease Ulcerative Enteritis.

Contributions to dentistry and oral health

Beginning in 1914, Bass commenced his investigations on the understanding of Entamoeba gingivalis (Endameba buccalis) in the microbiological flora of the mouth, beginning his interest in oral health. However, it was only upon his 1940 retirement from university administrative posts that he began intensive research on dental health, a period in which he made extensive use of his experience in parasitology and microbiology. Bass focused on the understanding and prevention of the principle diseases of the mouth, particularly caries and periodontoclasia. Bass carried out extensive investigation and experimentation to determine the best means of using toothbrushes and dental floss for effective prevention of the important diseases of the mouth. Bass widely promoted means of improved oral hygiene, purposefully avoiding his own personal profit in the interest of public health.

Bass developed an improved material for dental floss, namely nylon rather than the previous silk. His tenure included a tumultuous interaction with the administration of then Louisiana Governor Huey P. Long over the medical school's service of Charity Hospital (New Orleans). Bass eventually prevailed and established a teaching service at this large inner-city hospital.

Bass served as president of the Southern Medical Association in 1926.

Personal life and early career Bass was born on his family's pecan plantation in Carley, Mississippi, in Marion County, on January 29, 1875.

To further his investigations into hookworm and other aspects of parasitology, Bass enrolled in a one year course of study at the Johns Hopkins University School of Medicine. During his studies there in 1904, he worked with Dr. Charles E. Simon and with Dr. William S. Thayer to develop his investigational skills.

Awards and recognition Bronze doors commemorating Charles C. Bass were dedicated in Tulane University's Rudolph Matas Library in 1981. Among Bass's awards was a gold medal by the National Institute of Social Sciences for his contributions to the welfare of humankind. He was the 1967 recipient of an award from the Society for Preservation of Oral Health.
