Deciduous tooth eruption in Israeli children. A cross-sectional study

Area of Science:

• Pediatric Dentistry
• Human Growth and Development
• Anthropology

Background:

• Deciduous tooth eruption (DTE) is a critical developmental milestone.
• Understanding DTE patterns is essential for assessing child health.
• Variability in DTE can be influenced by various factors.

Purpose of the Study:

• To investigate deciduous tooth eruption patterns in a cohort of Jewish Israeli children.
• To determine if sex influences the number of erupted teeth (NET) at different ages.
• To examine correlations between NET and anthropometric measurements.

Main Methods:

• A cross-sectional study involving 366 Jewish Israeli children (193 boys, 173 girls).
• Data collection on the number of erupted teeth (NET) at various ages.
• Statistical analysis to compare NET between sexes and correlate with birth weight, length, weight, height, and head circumference.

Main Results:

• No statistically significant differences in NET were observed between boys and girls.
• No significant correlation was found between NET and anthropometric measurements at birth (weight, length).
• After controlling for age, NET showed no significant correlation with weight, height, or head circumference.

Conclusions:

• Sex does not appear to be a significant factor in deciduous tooth eruption timing or NET in this population.
• Anthropometric measurements are not reliable predictors of deciduous tooth eruption status in Jewish Israeli children.
• A wide range of normal variability exists in NET for a given age.
