Proportional changes in caries patterns from early to late primary dentition

Area of Science:

• Pediatric Dentistry
• Dental Public Health
• Caries Research

Background:

• Traditional tooth-oriented caries measures inadequately represent the full caries experience in primary dentition populations.
• Previous research has established child-based caries patterns and their quantification.
• Understanding caries distribution by etiology is crucial for targeted interventions.

Purpose of the Study:

• To investigate and compare proportional changes in primary dentition caries patterns across two distinct populations.
• To explore the utility of child-centered caries pattern analysis over tooth-specific averages.
• To suggest graphic representations for developing a predictive caries pattern model.

Main Methods:

• Examined children aged 2-5 years in urban pediatric and suburban private dental settings.
• Categorized children as caries-free or by specific etiology-oriented caries patterns (Fissure, Hypoplasia, Facial-Lingual, Molar-Approximal, FL/MA).
• Analyzed caries patterns based on individual child experience rather than tooth-specific indices.

Main Results:

• Over 85% of children aged 2.5 years and younger were either caries-free or presented with Facial-Lingual caries patterns.
• The Facial-Lingual pattern aligns with established descriptions of "nursing caries" in young children.
• Caries pattern trends observed were not discernible using conventional tooth-average measures.

Conclusions:

• Child-based caries pattern analysis offers superior insight into primary dentition caries experience compared to tooth-oriented measures.
• Early identification of specific caries patterns, like "nursing caries," is critical in preschool-aged children.
• Further development of graphic models for caries pattern analysis is recommended for public health applications.
