A True "Uomo Universale" from the 1800s - Dr. George Watt.

A hot bed of organized dental leadership and visionary thinking in the mid-to-late 1800s came from Ohio, as many presidents of the American Dental Association were from that state. They were quite influential in leading this organization into the 20th century. One of the most dynamic and well-rounded individuals was Dr. George Watt…this paper will highlight his life as viewed by one of his peers.

Historical perspectives on advertising and the meme that personal oral hygiene prevents dental caries.

The consensus of a leading scientific panel in 1930 was that oral hygiene products could not prevent dental caries. Their view was that dental caries prevention required the proper mineralisation of teeth and that vitamin D could achieve this goal. Over a hundred subsequent controlled trials, conducted over seven decades, largely confirmed that this scientific panel had made the right decisions. They had, in 1930, when it comes to dental caries, correctly endorsed vitamin D products as dental caries prophylactics and oral hygiene products as cosmetics. And yet, despite this consistent scientific evidence for close to a century, an opposing conventional wisdom emerged which thrives to this day: oral hygiene habits (without fluoride) protect the teeth from dental caries, and vitamin D plays no role in dental caries prevention. This historical analysis explores whether persistent advertising can deeply engrain memes on dental caries prevention which conflict with controlled trial results. The question is raised whether professional organisations, with a dependence on advertising revenues, can become complicit in amplifying advertised health claims which are inconsistent with the principles of evidence-based medicine.

The beginnings of professional dental institutions in 19th century America.

As we celebrate the 150th anniversary of the founding of the American Dental Association, it is important to understand that the birth of this organization had a gestation period of 30 years. Six events which took place between 1839 and 1845, and their subsequent sequelae, established American dentistry on a definite institutional foundation.

Dental hygienists' contributions to improving the nation's oral health through school-based initiatives from 1970 through 1999: a historical review.

PURPOSE: The purpose of this literature review is to document the contributions dental hygienists have made over the past 3 decades to improve the nation's oral health. This historical review encompasses selected literature that acknowledged dental Hygienists' direct involvement in U.S. school-based or school-linked oral health programs from 1970-1999. METHODS: Five researchers independently searched MEDLINE, PubMed, and other electronic databases to identify relevant literature for the years 1970-1999. The search aimed to locate articles authored by or that documented dental Hygienists' involvement as "service provider" in U.S. school-based oral health programs. For the purpose of this review, service provider was defined as educator, administrator, clinician, examiner, or any other unspecified service performed by a dental hygienist. RESULTS: Fifty-seven articles were retrieved, of which 36 (63%) directly linked dental hygienists to U.S. school-based activities. Twenty-seven articles specifically identified dental hygienists as service providers. Dental hygienists were listed as either primary or contributing author on 19 of these articles. CONCLUSION: The decade of the 1970s revealed very little literature documenting dental Hygienists' involvement in U.S. school-based oral health programs. The 1970s, however, were instrumental in laying the foundation for service in the years that followed. As public health initiatives expanded in the 1980s, dental hygienists were identified in the largest number of papers as key personnel in the areas of education, management, service provider, and author. The decade of the 1990s yielded less literature than the 1980s, yet recognized dental Hygienists' involvement in all aspects of oral health care delivery, program development and management, and authorship. The authors of this review theorize that dental hygienists were engaged in more school-based programs than reported and were involved in the authorship process more frequently than documented. Due to lack of credentials, or the omission of the words "dental hygienist," "RDH," or "LDH," in favor of "health care provider," "auxiliary," or "trained health care educator," it is unknown what portion of contributions made by dental hygienists remain undocumented.
