Teaching undergraduate geriatric dentistry in five South America countries.

Students' first contact with an older person usually occurs during clinical activities. The participants mentioned insufficient hours for GD modules in the curricula and exclusively theoretical modules that do not allow students to learn typical specificities of older people. In the context of this study, the undergraduate GD teaching-learning process presented some weaknesses regarding educational methods, professor training and the interaction between older people and students. Diversification of learning scenarios and GD professor training are highly recommended.
