Study Notes
Physical and Dental Changes in Children Aged Six to Twelve Years
- Children aged six years are typically 3'10" tall and 48 pounds, while twelve-year-olds are around 5' tall and 85 pounds.
- Children experience an average height increase of 5-6% and weight increase of 10% per year.
- By age six, all body proportions are close to those of adults, with the most remarkable proportional change being lengthening of the limbs.
- Boys experience the most significant height changes between ages 6-10, while girls experience the most significant height changes between ages 10-15.
- Blood pressure increases and pulse decreases, while mineralization of the skeleton and muscular tissue increase until age 11 in boys.
- Craniofacial changes include continuous growth in the head and neck, with the jaws growing faster than the cranium.
- Nasal projection and increased mandibular prominence occur, with the nasal cartilage and mandibular condyle continuing to grow.
- Growth modifications can be performed during this age group, with changes in cranial base length ceasing in early adolescence.
- Dentoalveolar growth complements facial growth as permanent teeth erupt and alveolar ridges develop.
- Transverse changes occur with the widening of the anterior arch and eruption of permanent teeth.
- All permanent teeth usually erupt by the end of the twelfth year, with enamel complete by age eight and root closure of several teeth by age 10-11.
- Diastemas between primary incisors provide space for larger permanent incisors, and ectopic eruption of teeth can occur during this period.
