Objectives: The purpose of the analyses was to study development, stability and changes in oral health behaviour; tooth brushing frequency, use of fluoride lozenges and fluoridated tooth paste in children from 1.5 to 5 years of age, and to study associations between oral health behaviour and family characteristics.
Methods: This study was based on data from the Norwegian Mother and Child Cohort Study conducted by the Norwegian Institute of Public Health and data from the Public Dental Services. A total of 771 children were followed from 1.5 to 5 years of age. Questionnaires regarding oral health behaviour in children were completed by the parents three times during preschool age.
Results: More than half of the children (52%) had their teeth brushed twice daily at 1.5 years of age, increasing to 61% at 3 years and 76% at 5 years of age. At 1.5 years of age 37% of the children used fluoride lozenges daily, increasing to 74% at 3 years and 75% at 5 years of age. The majority of the children who had started brushing twice daily and used fluoride lozenges daily at 1.5 year of age continued these behaviours until the age of 5 years. At 1.5 years of age, children who brushed twice daily were more likely to use fluoride lozenges daily than children who brushed less frequently (p = 0.03). Multiple logistic regression showed that the probability of a child having its teeth brushed twice daily continuously during preschool age was higher when both parents were of western origin (OR 4.0, CI 1.3 – 11.9) than when one or both parents were of nonwestern origin. Children with one older sibling brushed more frequently (OR 1.4, CI 1.0 – 1.9) and used fluoride lozenges more often (OR 1.6, CI 1.1 – 2.2) during preschool age than children without older siblings.
Conclusions: Oral health behaviour established in early life was stable during preschool age. The results indicate that tooth brushing frequency and use of fluoride lozenges were not in accordance with the present recommendations based on the scientific literature. The teeth of Norwegian pre-schoolers were brushed less frequently than recommended, and more children than recommended were using fluoride lozenges.
