Summary

Children with amelogenesis imperfecta (AI) exhibit accelerated dental development and a higher incidence of impacted permanent teeth. Early screening is recommended for orthodontic treatment planning in AI patients.

Area of Science:

  • Dentistry
  • Human Genetics
  • Pediatric Dentistry

Background:

  • Amelogenesis imperfecta (AI) is a group of inherited disorders affecting tooth enamel formation.
  • Understanding dental development in AI is crucial for clinical management and orthodontic planning.

Purpose of the Study:

  • To compare dental development and tooth impaction rates between children with AI and healthy controls.
  • To assess the correlation between AI and dental age acceleration.

Main Methods:

  • Dental age assessment using panoramic radiographs in 23 AI patients (4.2-15.6 years) and 46 controls.
  • Comparison of dental age with chronological age.
  • Evaluation of permanent tooth impaction and associated anomalies.

Main Results:

  • Subjects with AI demonstrated a significant dental age acceleration of approximately 1.13 years (P < 0.001).
  • AI patients showed a six-fold increase in permanent tooth impaction (26.1% vs. 4.3%).
  • Associated anomalies like follicular cysts were more prevalent in AI patients.

Conclusions:

  • AI is associated with accelerated dental development and increased risk of tooth impaction.
  • Early screening and orthodontic evaluation are essential for AI patients.
  • Findings aid in optimizing treatment strategies for individuals with amelogenesis imperfecta.
