As dental hygiene approaches its 100th anniversary in 2013, it is clear that the profession has evolved far beyond the initial vision of Dr. Alfred Fones. Much of this evolution has been driven by changing oral health needs of the public as well as the way dentists practice, based on innovations in dentistry, to concentrate on more advanced procedures and delegate other duties to the dental hygienist. By and large, these changes have been achieved by dentists, dental hygienists, and other team members working together. We have an opportunity to overcome initial resistance and, based upon evidence of successful outcomes, further extend the reach of the dental team for the benefit of patients, especially the most vulnerable among them.
