Summary

Early orthodontic intervention for children with slipped contacts may be beneficial. This study found significant increases in mandibular intercanine width during incisor transition, indicating potential for natural correction of crowding.

Area of Science:

  • Dentistry
  • Orthodontics
  • Pediatric Dentistry

Background:

  • Imperfect primary incisor spacing and mal-aligned permanent incisors often indicate a need for orthodontic treatment.
  • Clinical decisions for early intervention are frequently based on individual judgment due to limited evidence.

Purpose of the Study:

  • To investigate whether slipped contact arrangement warrants orthodontic intervention.
  • To determine the clinical significance of slipped contacts during incisor transition.

Main Methods:

  • Prospective study of 17 children with slipped contact arrangement.
  • Collection of orthodontic records from enrollment through full permanent dentition.
  • Measurement of slippage, space deficiency, and intercanine width changes.

Main Results:

  • Significant increase in mean mandibular intercanine width (2.58 mm, p=0.001) with permanent canine emergence.
  • Average slipped contact measured 3.21 mm; average space deficiency was 3.54 mm.
  • No correlation found between intercanine width and other orthodontic characteristics.

Conclusions:

  • Slipped contacts should be considered in early orthodontic treatment planning for childhood crowding.
  • Transitional correction mechanisms for slipped contacts are explained.
  • Further research is necessary to establish evidence-based parameters for early orthodontic treatment.
