Background:
Understanding the timing and variation of pubertal development is crucial for clinical orthodontics.
Longitudinal data on growth spurts, dental, skeletal, and pubertal maturation in children are essential.
Previous studies may lack representativeness or detailed longitudinal tracking.
Purpose of the Study:
To investigate the pubertal growth spurt and associated dental, skeletal, and pubertal development in Swedish children.
To assess the utility of various maturation indicators for clinical orthodontics.
To analyze sex differences and individual variations in developmental timing.
Main Methods:
Prospective longitudinal study of 212 randomly selected Swedish children from birth to adulthood.
Utilized maturation level indicators suitable for clinical orthodontics.
Statistical analysis accounted for low dropout rates and missing examinations.
Main Results:
A 2-year sex difference was observed in the timing of the pubertal growth spurt for standing height, with individual variations of approximately 6 years.
Dental development was more advanced in boys, while skeletal development showed sex differences at different stages of the growth spurt.
Dental emergence stages (DES) were not effective indicators of the pubertal growth spurt.
Conclusions:
The peak and end of the pubertal growth spurt can be assessed using skeletal and pubertal development indicators, but not dental emergence.
Skeletal maturation of the hand and wrist, along with menarche and voice change, are useful indicators for assessing the pubertal growth spurt.
Results are representative of Swedish children due to study design and low attrition.
