An innovative individual-level caries severity and progression indicator among children

Area of Science:

• Dental Public Health
• Pediatric Dentistry
• Epidemiology

Background:

• Dental caries remains a significant public health issue, particularly in young children.
• Traditional measures like decayed, missing, and filled surfaces (DMFS/dmfs) provide surface-level data.
• There is a need for individual-level indicators to better communicate caries severity and impact.

Purpose of the Study:

• To propose a novel individual-level indicator for caries severity using the International Caries Detection and Assessment System (ICDAS).
• To validate this indicator by comparing it with the conventional DMFS/dmfs index.
• To assess its utility in tracking caries progression over time.

Main Methods:

• A representative sample of 749 children under 6 years in Detroit was assessed twice (2002-2003 and 2004-2005).
• Children were categorized into six caries severity groups based on maximum ICDAS scores.
• The individual-level indicator was compared with the surface-level dmfs + DMFS measure, and caries progression was analyzed.

Main Results:

• A statistically significant linear relationship was found between the proposed individual-level indicator and the traditional DMFS/dmfs measure (P < 0.001).
• The indicator demonstrated the ability to track caries progression at both individual and tooth surface levels.

Conclusions:

• An individual-level caries progression indicator, derived from ICDAS, is feasible and valuable.
• This indicator offers a simple method to communicate the severity and impact of dental caries to policymakers and the public.
• It enhances the conventional presentation of DMFS/dmfs data, providing a more comprehensive view of the disease.
