[Nutrition education in dentistry].
Reduction of the number of sugar containing snacks is the most important nutritional measure to prevent dental caries. Frequent use of acid food and drinks can lead to erosion of the enamel. Snacks containing as little fat and as much complex carbohydrates and rough materials as possible are preferred. In nutrition education, general principles of health education, such as attention for personal and social circumstances, have to be kept in mind. Prolonged use of the nursing bottle containing sugar-rich drinks must be prevented. Attention is needed for young people who frequently use soft drinks, sportsmen and women, people with a special dietary pattern, 'grazing' people and people with an illness or handicap.
