A questionnaire about the dental treatment for visiting patients at Welfare center for the aged people. Nowadays, 11 percent of the population is over 65 in Japan. According to the Minister of Health and Welfare's Population Projection for Japan, it will grow to 20% at the beginning of the 21st century. Problems concerning old people will become some of Japan's biggest challenges. In that situations, the dental treatments for visiting aged patients will become more important. Then, authors sent out a questionnaire about it on aged people who have no need of anyone's assistance in their home lives. And we examined concrete countermeasures and problems about the dental treatments for visiting patients. The findings were as follows: 1. Even the aged people who have no need of anyone's assistance in their home lives, they hope much carrying out the dental treatments for visiting them. 2. The dental treatments for visiting aged patients have some problems. But it will become one of the most important way to supply their demand for dental treatments, in spite of their latent requirements, a lot of old people give up to undergo dental treatments.
