A novel staging system for caries severity in the primary dentition

Area of Science:

• Pediatric Dentistry
• Dental Public Health
• Clinical Epidemiology

Background:

• Dental caries in primary dentition (CIPD) is highly prevalent in U.S. children, with significant health disparities.
• Existing metrics like ECC and dmft do not adequately assess the clinical morbidity associated with CIPD.
• Morbidity includes pain, speech delay, and restorative trauma, impacting a child's quality of life.

Purpose of the Study:

• To introduce a novel construct, "CIPD Levels," for staging caries severity in children aged 0-5.
• To correlate age-specific dmft scores with current and predicted child morbidity.
• To provide a metric for assessing individual and group disease burden.

Main Methods:

• A matrix was developed assigning CIPD Levels 0-4 based on dmft scores (0-7) and age.
• CIPD Level-4 represents the highest severity, associated with adverse outcomes.
• The matrix was validated using data from a high-risk pediatric population.

Main Results:

• 82.8% of children with cavitated caries before 24 months reached CIPD Level-4 by 36 months.
• Conversely, 71.4% of children with a dmft score of 0 at 24 months did not reach CIPD Level-4 by 36 months.
• These findings demonstrate the metric's ability to differentiate risk and progression.

Conclusions:

• The developed "CIPD Levels" metric effectively quantifies caries disease burden in high-risk children.
• This staging system offers a more clinically relevant assessment of morbidity than traditional metrics.
• The metric shows promise for improved clinical decision-making and public health surveillance.
