Key Takeaway
Note that the collaborative management model shows statistically significant improvements in oral health metrics for preschool children.

This prospective single-arm pre-post intervention study evaluated a "family-school-hospital" collaborative oral health management model in 421 preschool children in Chengdu, China. The model included population screening, personalized guidance, diagnostic pathways, and health behavior tools. Follow-up assessments were conducted at 1, 3, and 6 months.

Significant improvements were observed across multiple secondary outcomes. The number of teeth restored, the number of children participating in fluoride application or pit and fissure sealing, and the number of children using fluoride toothpaste all showed statistically significant increases. Additionally, the plaque index showed a statistically significant decrease. Oral health-related quality of life scores and parental knowledge and attitude also showed statistically significant improvements.

Safety data were not reported, though there was a 11.4% loss to follow-up. The study is limited by its single-arm design and the lack of randomized controlled trials with longer follow-up periods to confirm long-term preventive efficacy. This model provides a reference framework for preschool oral health management, but results should be interpreted as associations rather than proven causal effects.

How this fits prior evidence

How this fits prior evidence: This finding extends the understanding of management strategies for early childhood caries, which is recognized as a developmental ecological disorder influenced by maternal and environmental factors. While prior evidence confirms that topical fluoride significantly reduces dental caries incidence in children and adolescents, this study evaluates a multi-faceted collaborative model. The results complement existing evidence that both SMART and ART are viable options for caries control in primary teeth by providing a framework for integrated community-based management.

Early childhood caries, or cavities, can start a lifetime of dental issues for young children. To tackle this, researchers in China tested a collaborative oral health management model. This approach combined efforts from families, schools, and hospitals to provide personalized guidance and better tools for managing children's dental health.

The study followed 421 preschool children. The results showed that this team-based approach led to a significant increase in the number of teeth restored and a decrease in plaque levels. It also led to more children participating in fluoride treatments and using fluoride toothpaste. Beyond just the physical results, the program improved the quality of life scores related to oral health and improved the knowledge and attitudes of the children's parents.

While these results are promising, it is important to note that this was a single-arm study, meaning there was no separate group to compare the results against. Because of this design, the study shows an association rather than a direct cause. More randomized controlled trials with longer follow-up periods are needed to confirm how well this method prevents cavities over time.

What this means for you:
A team-based approach involving families and schools can improve dental health and parent knowledge in preschoolers.

Common questions

How does this program help children with cavities?

The program uses a collaborative model involving families, schools, and hospitals. It provides personalized guidance and tools to help children. The study of 421 children showed that this approach led to a significant increase in the number of teeth restored and a decrease in plaque levels.

Does this program help parents understand dental health better?

Yes, the study found that the collaborative management model led to a significant improvement in parental knowledge and attitude regarding oral health. This helps parents better support their children's dental care.

Is this a proven long-term prevention method?

The study shows a positive association between the program and better oral health. However, because it was a single-arm study, more randomized controlled trials with longer follow-up periods are needed to confirm the long-term preventive effects.

Early childhood caries (ECC) remains a global public health challenge, yet preschool children lack autonomy in health management and depend heavily on family and school environments. Population-based oral health management models have proven effective in other fields but are rarely implemented in Chinese preschool settings. This study aimed to establish and evaluate a “family-school-hospital” collaborative oral health management model for preschool children in Chengdu, China. The oral health management model for preschool children was established through population screening, baseline surveys, personalized oral health guidance, provision of diagnostic and treatment pathways, and the use of health behavior formation tools. The preliminary effects of promoting active health behavior formation were observed through oral health follow-up examinations and oral health-related questionnaire surveys conducted at 1-, 3-, and 6-month follow-ups. After establishing the oral health management model for preschool children, a total of 421 children completed the six-month follow-up, with a loss to follow-up rate of 11.4%. The increase in the number of teeth restored, the decrease in plaque index, the increase in the number of children participating in fluoride application or pit and fissure sealing, the improvement in the number of children using fluoride toothpaste, the improvement in oral health-related quality of life scores, and the improvement in parental knowledge and attitude were all statistically significant. This collaborative model was associated with improved parental knowledge and attitudes, enhanced children's oral hygiene and restorative care, and better oral health-related quality of life. It offers a reference framework for preschool oral health management. Future randomized controlled trials with longer follow-up are warranted to confirm its preventive efficacy.
