Insights
High caries risk and prevalence were found in Lebanese preschoolers, with over 74% having carious lesions and nearly 40% at very high risk. Oral hygiene and parental education significantly impact early childhood caries.
Area of Science:
- Pediatric Dentistry
- Oral Health Epidemiology
- Public Health
Background:
- Early childhood caries (ECC) poses a significant global health challenge.
- Understanding ECC prevalence and risk factors in diverse populations is crucial for targeted interventions.
Purpose of the Study:
- To determine the prevalence of early childhood caries and assess caries risk among Lebanese preschoolers.
- To identify correlations between oral hygiene, dietary habits, parental factors, and caries development.
Main Methods:
- A cross-sectional study involving 99 Lebanese preschoolers (≤4 years old).
- Data collection included parental questionnaires (diet, hygiene, education), clinical oral examinations, and salivary tests (buffer capacity, Streptococcus mutans, Lactobacillus).
- A validated caries risk assessment tool categorized children into low, moderate, high, or very high risk groups.
Main Results:
- 74.7% of children had at least one carious lesion; 22.2% had over 10 lesions.
- High to very high plaque scores (≥ moderate) were observed in 70.7% of subjects.
- 40% of children were classified as very high caries risk (C3), and 15.1% as high risk (C2).
- High levels of Streptococcus mutans and Lactobacillus were prevalent and correlated with caries.
- Factors like regular tooth brushing, systemic fluoride, parental education, and regular dental visits were associated with lower plaque and caries scores.
Conclusions:
- A high prevalence of early childhood caries and a significant proportion of Lebanese preschoolers are at high or very high caries risk.
- Oral hygiene practices, parental education, and access to dental care are critical modifiable factors.
- Further research is warranted to explore these findings in the broader Lebanese preschool population.
Objectives:
This study describes early childhood caries prevalence and caries risk in a group of Lebanese preschoolers.
Method And Materials:
99 healthy children, aged four years or less, were recruited at the Dental medicine faculty, Saint-Joseph university, Beirut, Lebanon. After parental consent, questionnaires investigated children's dietary and oral hygiene habits and parents' education and health behaviors. Oral examinations, with bite-wing radiographs when necessary, determined decayed-filled surfaces and plaque scores. Salivary testing assessed buffer capacity and streptococcus mutans (Sm) and lactobacillus (Lb) presence. The three tests (questionnaire, oral examination, salivary testing) established a caries risk assessment tool, determining subjects' caries risk scores, classified as low (C0), moderate (C1), high (C2) or very high (C3).
Results:
25.3% of subjects were caries-free, 24.2% had 4 carious lesions or less, 28.3%, 5 to 9 lesions and 22.2% over 10 lesions. 11.1% of plaque scores were low to mild, 18.2% moderate, 46.4% high, and 24.3% very high. Salivary buffer capacity was: 29.3% high, 57.6% medium and 13.1% low. High levels of Sm, (66.7%) correlated with plaque presence and proximal caries. High levels of Lb (52.5%) correlated with plaque presence and smooth-surface caries, and correlated significantly with occlusal caries. Regular tooth brushing yielded lower plaque, but not significantly lower caries levels. Systemic fluorides were associated with lower plaque and caries scores. Children of educated parents with regular dental visits and oral hygiene had lower plaque and caries scores. Caries risk distribution was: CO: 16.2%, C1: 29.3%, C2: 15.1% and C3: 39.4%.
Conclusion:
Most subjects had at least one carious lesion (74.7%), and 70.7% showed high to very high plaque scores. Over half the sample presented high or very high caries risk. These findings deserve further investigation of the Lebanese preschoolers' population.

Tooth Anatomy
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.
Assessment of the Mouth
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
