The world's population is in transition, but there is an inevitable move in all societies towards an aging population. There is an agreement that the ability of the geriatric population to adjust to the "third age" depends on the will of the society and the community to provide services and to support this vulnerable and dependent population. The preponderance of oral health issues and their impact upon general health and quality of life have prompted a variety of geriatric related efforts over the last 20 years. Predoctoral and postdoctoral education and training efforts have been initiated, geriatric research agendas have started to yield important findings, and a few service programs have marginally helped improve dental care access for the geriatric population. Past discoveries have enabled large portions of the world's population to enjoy far better oral health than their forebears a century ago. Although different patterns of dental needs emerge throughout the world, the" silent epidemic" of oral diseases is affecting the most vulnerable parts of the population: the poor children, the elderly and many members of racial and ethnic minority groups. The review of the literature of community aspects of geriatric dentistry in the past twenty five years will be introduced in two articles. The first article summarizes the important issues of demography, oral health condition, changes in attitude towards oral health of the geriatric population, oral health services given in geriatric institutions and mobile dentistry. The issues of law and ethics, development of public and community oral health programs for the geriatric population and plans as well as trends for the future will be discussed in the second article. Setting goals and presenting data are steps in the right direction but are not enough; the success will be measured by the ability to make things happen. The continuing anticipated growth of the geriatric population will, hopefully, be translated into a rising political power and to fruitful and practical health outcomes.
