Dental age and skeletal age show only moderate associations in children. One maturity measure cannot reliably predict the other, highlighting the need for distinct assessments in orthodontic evaluations.

Area of Science:

  • Orthodontics and Dental Development
  • Pediatric Health and Growth

Background:

  • Accurate assessment of developmental maturity is crucial in orthodontics.
  • Understanding the relationship between dental and skeletal maturity aids treatment planning.

Purpose of the Study:

  • To analyze the association between dental maturity and skeletal maturity in untreated children.
  • To determine if dental age can be used to infer skeletal age, or vice versa.

Main Methods:

  • Utilized data from 694 untreated children in a private orthodontic practice.
  • Assessed dental age using Bolton Standards and skeletal age via the Greulich-Pyle atlas.
  • Performed regression analyses to quantify the association between dental and skeletal ages.

Main Results:

Related Experiment Videos

  • Significant variability observed, with differences between dental and skeletal ages up to 36 months.
  • Fewer than 40% of children exhibited a difference of less than 6 months.
  • Regression analyses indicated only moderate associations between the two maturity measures.

Conclusions:

  • Dental age and skeletal age are only moderately associated in children.
  • Inference of one maturity measure from the other is unreliable.
  • Both dental and skeletal assessments are necessary for comprehensive developmental evaluation in orthodontics.
