That is, mastication and speech as a primary function, and finally for nutritional requirements, especially in the elderly. This literature review was conducted to evaluate the treatment outcomes of prosthodontic treatment for the elderly with two nutritional hypotheses: 1) prosthodontic intervention improves the diversity of food intake, and 2) prosthodontic intervention improves nutritional status. There is weak evidence that prosthodontic treatment can improve dietary intake; however, it could affect less the nutritional condition in comparatively healthy elderly individuals. The combination of prosthodontic treatment and nutritional guidance demonstrated nutrient intake efficiency. http://pubs.sciepub.com/jfnr/10/1/4/jfnr-10-1-4.pdf prosthodontic treatment oral function elderly nutrition food intake
