A dental caries severity index for primary teeth.

Area of Science:

• Pediatric Dentistry
• Dental Public Health
• Cariology

Background:

• Dental caries is a significant public health concern in primary dentition.
• Existing indices like def (decayed, extracted, filled) may not fully capture caries severity.
• A need exists for a more comprehensive measure of caries attack on affected teeth.

Purpose of the Study:

• To describe the criteria for the Caries Severity Index (CSI).
• To evaluate the CSI's effectiveness in assessing caries severity in primary teeth.
• To compare CSI with the defs index across different fluoride exposure levels.

Main Methods:

• Developed a scoring system for caries on each tooth surface (1-3).
• Calculated tooth score as the sum of surface scores.
• Defined CSI as the mean score of all carious teeth in a population.
• Examined three groups of children (5-6.5 years) with varying water fluoride levels.

Main Results:

• CSI scores varied across populations with different fluoride levels (Jerusalem 2.99, Soshanguva 3.10, rural Africa 1.93).
• The defs index also showed variation (Jerusalem 10.19, Soshanguva 5.75, rural Africa 1.99).
• Interexaminer and intraexaminer reproducibility for CSI were found to be good.

Conclusions:

• The Caries Severity Index (CSI) is a reproducible and reliable measure of caries severity.
• CSI provides additional, valuable information compared to traditional def indices.
• CSI can enhance the assessment of dental caries impact in epidemiological studies.
