Orthodontic forces on deciduous teeth can cause significant root resorption, differing from natural processes. Monitoring these teeth with X-rays is recommended to prevent fractures.

Area of Science:

  • Dentistry
  • Orthodontics
  • Pediatric Dentistry

Background:

  • Root resorption is a known complication of orthodontic treatment.
  • The effects of orthodontic forces on deciduous (baby) teeth root resorption have not been previously investigated.

Purpose of the Study:

  • To investigate the relationship between orthodontic forces and root resorption in deciduous molars.
  • To compare root resorption in orthodontically treated deciduous teeth versus untreated controls.

Main Methods:

  • Histological and histomorphometric analysis of 24 extracted deciduous molars (19 treated, 5 control).
  • Evaluation of the location, extent, and volume of root resorption.

Main Results:

  • Root resorption in treated teeth occurred in different locations compared to physiological resorption.

  • The extent and volume of root resorption were significantly greater in deciduous molars subjected to orthodontic forces.

    • Conclusions:

    • Orthodontic treatment can induce significant root resorption in deciduous teeth.
    • Radiographic monitoring of deciduous teeth under orthodontic forces is advisable to mitigate risks like root fracture.
