The prevalence of traumatic injuries to the primary dentition ranges
from 11%?30%, but the incidence of dilacerated permanent teeth is very low and
disproportionate to high prevalence of trauma. Hence, traumatic injuries to the
primary dentition are unlikely to account for all cases of dilaceration and
especially those of primary teeth themselves. An idiopathic developmental
disturbance to deciduous dentition is proposed as another possible cause in
cases that have no clear evidence of traumatic injury. The prime objective of
the present article is to discuss cases of dilaceration in the deciduous
anterior teeth and review the previous studies on dilacerations of the
deciduous dentition. - See more at:
