Nutrition and Dental Health in Toddlers

Early life, including the toddler period, represents a critical phase for physical growth and tissue development, including hard dental tissues such as enamel and dentin. Adequate nutrition is essential to ensure proper mineralization, structural strength, and resistance to dental caries. Although the study referenced in this article focused on children aged 6–7 years, its findings provide insights into how nutritional status may relate to dental health and its implications for younger children.

A study conducted by an FKG UGM student, Ellysa Ardiani, under the supervision of Dr. rer. nat. dr. BJ. Istiti Kandarina and drg. Lisdrianto Hanindriyo, MPH., Ph.D., found no significant association between nutritional status and the incidence of caries in permanent mandibular first molars among children aged 6–7 years (p = 0.84). However, the study noted that cariogenic dietary patterns were associated with caries, although the association became non-significant after adjustment.

This suggests that while nutritional status may not be directly associated in this case, nutrition remains an important factor in caries risk contexts.

Relationship Between Nutrition and Dental Health in Toddlers

Biological Mechanisms

1. Mineralization and Enamel/Dentin Growth
   • Calcium, phosphorus, vitamin D, and trace elements (such as fluoride and magnesium) are essential for the formation and maintenance of dental mineral structures. Deficiencies can make enamel more susceptible to demineralization.
2. Immunity and Resistance to Infection
   • Malnutrition can weaken the immune system, allowing cariogenic bacteria to proliferate more easily.
3. Saliva Changes and Buffering Capacity
   • Poor nutrition or inadequate hydration can affect saliva production and buffering capacity, both of which are crucial for acid neutralization and remineralization.
4. Carbohydrate and Sugar Intake (Cariogenic Diet)
   • High intake of sugars or fermentable carbohydrates plays a major role in caries development, even when overall nutritional status may not be directly associated, as observed in the UGM study.

Findings from the UGM Study

• The study involved 38 children aged 6–7 years living in orphanages, assessing nutritional status using BMI-for-age and clinically examining caries in permanent mandibular first molars. ETD UGM
• Results showed no significant association between nutritional status and caries incidence (p = 0.84; OR = 0.85; 95% CI = 0.14–4.94). ETD UGM
• Cariogenic dietary intake was initially associated with caries incidence (p = 0.036; OR = 5.72), but the association became non-significant after adjustment for confounding variables (p = 0.86; OR = 0.88). ETD UGM
• The authors concluded that “poor nutritional status does not increase the incidence of caries in permanent mandibular first molars among children aged 6–7 years.” ETD UGM

Implications for Toddlers

Although the study did not directly involve toddlers, the following principles apply:

• Early stages of tooth formation and mineralization occur at a very young age; poor nutrition during toddlerhood can weaken primary teeth and affect the transition to permanent teeth.
• Toddlers are more vulnerable to sugary foods and drinks, increasing the risk of early childhood caries.
• Proper nutritional interventions can support dental and periodontal tissue development, creating healthier conditions before permanent teeth erupt.

Intervention Strategies

1. Balanced Nutrition from an Early Age
   • Ensure adequate intake of calcium, phosphorus, vitamin D, protein, and micronutrients
   • while limiting added sugars.
2. Parent and Caregiver Education
   • Educate caregivers on healthy dietary patterns, oral hygiene practices
   • the use of fluoride toothpaste when recommended.
3. Regular Dental Check-Ups
   • Early screening for caries and preventive measures such as topical fluoride and sealants.
   • Pendekatan preventif seperti fluoride (topikal) dan sealant pada gigi molar ketika tumbuh.
4. Integrated Nutrition and Oral Health Programs
   • Incorporate oral health education into nutrition programs at early childhood institutions, PAUD, and orphanages.
   • Monitoring status gizi dan status gigi secara berkala.
5. Further Research
   • Longitudinal studies in toddlers to evaluate long-term effects of nutritional status on caries development.
   • Penilaian kombinasi faktor (gizi, kebersihan mulut, asupan gula) agar dapat identifikasi determinan dominan.

***

In conclusion, although the UGM study found no significant association between nutritional status and caries incidence among children aged 6–7 years, nutrition remains critical for toddler dental health due to its role in mineralization, immunity, and caries risk modulation. Early-life interventions combining nutrition, education, sugar intake control, and preventive dental care are essential to maintain oral health from an early age.
