Evaluation of a computer program for caries risk assessment in schoolchildren

Area of Science:

• Dentistry
• Public Health
• Preventive Medicine

Background:

• Dental caries remains a significant public health concern, particularly among children.
• Accurate caries risk assessment is crucial for effective preventive strategies.
• Existing methods for caries risk evaluation have limitations in predicting future disease progression.

Purpose of the Study:

• To assess caries risk in schoolchildren using the Cariogram software.
• To evaluate the predictive accuracy of the Cariogram by comparing its risk assessments with actual caries development over two years.
• To identify the most significant factors associated with caries increment in a pediatric population.

Main Methods:

• A 2-year prospective study involving 446 schoolchildren aged 10-11 years.
• Baseline data collection included general health, diet, oral hygiene, fluoride use, and saliva analyses (mutans streptococci, lactobacilli, buffer capacity, secretion rate).
• Dental caries status (DMFT, DMFS) was recorded, Cariogram scores were entered for risk assessment, and children were re-examined for caries after two years.

Main Results:

• The Cariogram demonstrated a strong correlation between predicted risk and actual caries incidence.
• Children predicted to be at high risk by the Cariogram had a significantly higher likelihood of developing new caries.
• The Cariogram was the most powerful predictor of caries increment, outperforming individual factors like lactobacillus count, mutans streptococci, diet, and past caries experience (DMFS).

Conclusions:

• The Cariogram is a valuable and accurate tool for assessing caries risk in schoolchildren.
• Its comprehensive approach, integrating multiple factors, provides superior predictive power compared to single-factor models.
• Further research is needed to optimize the integration of the Cariogram into daily dental practice for enhanced caries prevention.
