Lower incisor crowding initially decreases with tooth eruption but later increases. Early measurements of lower incisor space are unreliable for predicting final crowding in permanent dentition.

Area of Science:

  • Dentistry
  • Orthodontics
  • Human Growth and Development

Background:

  • Assessing lower incisor alignment changes is crucial for predicting and managing dental crowding.
  • Understanding developmental changes in the mandibular arch informs orthodontic interventions.

Purpose of the Study:

  • To track lower incisor alignment changes from eruption through permanent dentition.
  • To evaluate the predictability of early developmental stages for later incisor crowding.

Main Methods:

  • Longitudinal study of 48 subjects from the Belfast growth study.
  • Measurement of lower incisor space condition at four distinct developmental stages.
  • Statistical analysis of changes and correlations between developmental stages.

Main Results:

  • A statistically significant decrease in lower incisor crowding (-0.9 mm) occurred between initial incisor eruption and canine eruption.
  • A significant increase in crowding (0.4 mm) was observed between second molar eruption and 3 years post-eruption.
  • Correlations existed between space conditions at different stages, but were deemed unreliable predictors.

Conclusions:

  • Lower incisor crowding exhibits dynamic changes during dental development.
  • Predicting mature lower incisor crowding based on early developmental stages is unreliable.
  • Further research may be needed to identify reliable predictors for orthodontic treatment planning.
