This study found that boys

Area of Science:

  • Pediatric Dentistry
  • Human Growth and Development

Background:

  • Understanding the timing of primary tooth eruption is crucial for monitoring child development.
  • Variations in eruption patterns can indicate underlying developmental or health issues.

Purpose of the Study:

  • To determine the precise eruption time and sequence of primary teeth in Korean children.
  • To identify any sex-based differences in primary tooth eruption patterns.

Main Methods:

  • A random sample of 1070 Korean children aged 4–36 months was examined.
  • Median values were utilized to analyze the eruption chronology of deciduous teeth.
  • Data was collected on both male and female participants.

Main Results:

  • Primary teeth eruption occurred earlier in boys compared to girls.
  • Mandibular central incisors and second molars erupted prior to their maxillary counterparts.
  • Maxillary lateral incisors, canines, and first molars erupted before their mandibular counterparts.

Conclusions:

  • The study provides normative data on primary tooth eruption for Korean children.
  • Sex influences the timing of primary tooth eruption, with boys exhibiting earlier eruption.
  • Specific eruption sequences were identified, differing between maxillary and mandibular teeth for certain tooth types.

Teeth

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
