Insights
Giving children under two years old free sugars in foods and drinks significantly increases their risk of early childhood caries by age five. Limiting sugar intake early is crucial for preventing dental problems.
Area of Science:
- Pediatric Dentistry
- Public Health Nutrition
- Epidemiology
Background:
- Early childhood caries (ECC) is a prevalent issue affecting young children's oral health.
- Dietary habits established in early life significantly influence long-term health outcomes, including dental health.
Purpose of the Study:
- To examine the association between early-life exposure to free sugars in foods and beverages and the incidence of early childhood caries (ECC) by age five.
- To provide evidence-based recommendations for caregivers and healthcare professionals regarding sugar consumption in children under two years old.
Main Methods:
- A cohort study involving 208 children, tracking feeding habits and dietary intake from birth to 24 months via questionnaires.
- Dental caries assessment (decayed, missed, filled teeth) using WHO criteria at five years of age.
- Statistical analysis using chi-square tests and relative risk (RR) with 95% confidence intervals to determine associations.
Main Results:
- Twenty-two percent of children developed caries by age five.
- Consumption of fruit juice with meals (RR 2.3), cookies/biscuits at 24 months (RR 2.4), and weekly fast food intake (RR 2.9) significantly increased ECC risk.
- These dietary factors more than doubled the risk for early childhood caries.
Conclusions:
- A clear link exists between early-life free sugar consumption and the prevalence of dental caries at age five.
- Emphasizing current sugar recommendations in primary and dental care is vital.
- Educating caregivers to avoid offering free sugars to children before the age of two is recommended to prevent ECC.
Purpose:
To investigate the impact of giving children younger than 2 years foods and beverages with free sugars on the prevalence of early childhood caries at 5 years.
Materials And Methods:
The study group consisted of 208 children (105 boys and 103 girls) with a complete set of data on nursing, diet and caries from birth to 5 years. We collected feeding habits and dietary data through structured questionnaires at 6, 12, 18 and 24 months and the presence of decayed (d), missed (m) and filled (f) teeth was scored according to the WHO criteria at five years of age. We processed data with chi-square tests and expressed as relative risk (RR) with 95% confidence intervals.
Results:
At the age of 5 years, 22% of the children had caries. Intake of fruit juice with meals (RR 2.3) and cookies or biscuits at 24 months of age (RR 2.4), as well as fast food consumption at least once every week (RR 2.9), more than doubled the risk for early childhood caries (p < 0.05).
Conclusions:
Within the limitations of the present study, we found a relationship between consumption of free sugars early in life and dental caries prevalence at 5 years. It therefore seems important to embrace and emphasise the current sugar recommendations in primary and dental care to educate caregivers to avoid serving free sugars to their children before the age of 2 years.

In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
