This article reviews the life story and contributions of Sumter Smith Arnim
(1904-1990), a noted author, lecturer, teacher, and researcher in
preventive dentistry. Following in the footsteps of Levi Spear Parmly, MD,
DDS (1790-1859), and Charles C. Bass, MD (1875-1975), Arnim developed and
popularized a wide range of preventive concepts and practices, especially
dental plaque control via mechanical means. Today, these innovative ideas
and techniques continue to have an impact on oral health research, the
practice of dentistry, and the teaching of oral hygiene to dental patients.
This article traces both the development of these oral health concepts and
Arnim's study of dental plaque ("microcosm"), which he characterized by
means of phase-contrast microscopy and cinemicrography.
