Insights

A new caries risk assessment model effectively screens preschool children for early childhood caries (ECC) in rural China. This accessible online platform aids community-level dental health management.

Area of Science:

  • Public Health
  • Pediatric Dentistry
  • Health Informatics

Background:

  • Early childhood caries (ECC) poses a significant global health challenge, requiring effective early screening methods.
  • Underdeveloped regions, particularly in Northwest China, face unique barriers to managing ECC in preschool populations.

Purpose of the Study:

  • To develop and validate a caries risk assessment (CRA) platform tailored for community preschool children in underdeveloped areas of Northwest China.
  • To establish an accessible tool for early detection and management of ECC.

Main Methods:

  • Data collection included clinical examinations and questionnaires from 3-5-year-old children across six regions in Gansu Province.
  • Least Absolute Shrinkage and Selection Operator (LASSO) regression identified key predictive variables, followed by multivariate logistic regression for model construction.
  • Model performance was evaluated using receiver operating characteristic (ROC) curves, calibration, and clinical decision/impact analyses.

Main Results:

  • The validated CRA model incorporates age, residence, infant feeding patterns, toothache history, and dental visit history.
  • The model demonstrated excellent discriminatory performance with an Area Under the ROC Curve (AUC) of 0.804 and good predictive accuracy.
  • An online prediction platform was developed for public accessibility and practical application.

Conclusions:

  • The developed CRA model provides a novel public platform for screening and managing deciduous caries in community settings.
  • This tool is particularly valuable for addressing ECC in underdeveloped regions of Northwest China.
  • The platform facilitates community-level dental health management and early intervention for ECC.
