Does impaction effect root developments
Research on impacted teeth
· Impacted incisors study by Chaushu
o Impacted teeth: Root length shorter by 3.1mm
o Root volume – normal
o Hooked apex = 40%
o Prevalence of dilaceration increases with age
§ Understanding if the tooth develops against an anatomical structure, the tooth roots develop dilacerated
· Impacted maxillary canine Dekel 2021
o Root length 1.2mm shorted, root volumes normal
o 2-3 x greater dilacerated canines when impacted
Conclusion:
Impaction does effect root development
· Shorter roots and root dilaceration
· Effect incisors more than canines – possibly due to inisors developing against the base of the nose
Can we erupt teeth with impaired root development?
· Intrinsic eruption potential is unaffected by root shape
· Treatment is longer due to greater tooth displacement – average 3.4 months Chaushi 2015
Can we modify root development by early treatment?
· Early treatment can aid development of root development
o Understanding the root develops away eruption
· Can plan orthodontic treatment when apucal 1.3 developed = 7-8 years of age
