Caries experience as predictor for caries incidence

Area of Science:

• Pediatric Dentistry
• Dental Public Health
• Caries Research

Background:

• Early childhood caries prevalence is a significant predictor of future dental health.
• Identifying children at high risk for caries progression is essential for preventive strategies.
• Fluoride mouthrinsing is a common public health intervention for caries prevention.

Purpose of the Study:

• To compare caries increment in children with low versus high caries prevalence at age 8.
• To evaluate the effectiveness of a fortnightly fluoride mouthrinsing program in different risk groups.
• To identify early indicators for high caries risk in children.

Main Methods:

• Longitudinal study comparing caries increment (filled surfaces) from ages 7 to 15.
• Two groups: low prevalence (≤3 filled surfaces) and high prevalence (≥8 filled surfaces) at age 8.
• Participants engaged in a fortnightly 0.2% sodium fluoride (NaF) mouthrinsing program.

Main Results:

• The high prevalence group showed a significantly higher caries increment (17.1 surfaces) compared to the low prevalence group (11.4 surfaces) over 8 years.
• Significantly more fillings were required in the high prevalence group (31.1) than the low prevalence group (15.5).
• High caries prevalence and a high fillings-to-caries increment ratio at ages 7-8 identified children at higher risk.

Conclusions:

• Children with high caries prevalence at age 8 exhibit a greater caries increment, even with regular fluoride prophylaxis.
• Early identification of caries risk factors, including initial prevalence and increment rates, is vital.
• Social class and tooth count were less predictive of caries increment than initial prevalence.
