Geriatric dentistry in the next millennium: opportunities for leadership in oral health.

"The twentieth century will be remembered chiefly, not as an age of political conflicts and technical inventions, but as an age in which human society dared to think of the health of the whole human race as a practical objective." Arnold Toynbee, British historian. Individuals throughout the world often view the passage of a new year as a time for re-evaluation of personal and/or professionals goals. The new millennium offers the dental profession a chance to view the future and observe the challenges and opportunities facing it. Professor Toynbee's observation is particularly poignant when one considers the improvements in oral health made in the last 100 years. Caries, once considered a ubiquitous oral disease, has been prevented in some children in developed countries. Research on periodontal disease continues to identify risk factors and the pathobiological mechanisms underlying the disease. Concurrently the population of the world is aging presenting new opportunities for improving oral health. In this paper the data on aging, chronic diseases and oral health is largely from the US but reflects to varying degrees other industrial countries. By integrating these demographic, epidemiologic and biologic data, one can paint a portrait of the future dental patient and their oral health needs. From this portrait, dental professionals can identify leadership opportunities to improve the oral health of an aging world population.
