Analysis of caries-related factors in infants and toddlers living in Sweden.

The aims of this study were 1) to investigate whether oral hygiene and dietary habits established at 1 year of age are maintained at 2 years of age and 2) to analyze caries-related factors with regard to oral health between the age of 1 and 3 years by using the salutogenic theory-that is, focusing on behavioral factors that do not result in impairment of health. Altogether 289 children were examined at 1, 2, and 3 years of age, and their parents were interviewed about the children's oral hygiene and dietary habits at 1 and 2 years of age. The result shows that caries-related habits, such as oral hygiene and dietary habits, established during infancy are maintained throughout early childhood. The principles of the salutogenic theory were found to be applicable when studying caries-related habits and oral health. Thus, if a dietary risk behavior is established at 1 year of age, the chance of remaining caries-free until 3 years of age is highest if good oral hygiene habits, including the use of fluoride toothpaste, are present at 2 years of age. We therefore conclude that comprehensive knowledge of a child's future dental health can be obtained by using chairside information-that is, interview of the parents and clinical examination of the children.
