Nutritional and Oral Hygiene Knowledge versus Reported Behavior of Children and Adolescents-A Cross-Sectional Interview-Based Study.

Despite the fact that healthy, sugar-reduced nutrition has been propagated by the media and in schools for years, dental caries in children remains a major health problem worldwide, caused primarily by an unhealthy diet. The objective of this study is to compare statements on nutrition and hygienic knowledge with those on children's actual dietary and hygienic behavior. A random sample of 554 children and adolescents aged 3-19 years was enrolled.
