Resumo
The purpose of this study was to evaluate the epidemiological aspects associated with avulsion
of primary teeth. The sample consisted of 92 avulsed teeth of 69 patients seen at the dental urgency
service of the Dental School of the Federal University of Goiás, Brazil, from 1998 to 2005. The data
obtained from the records included children’s gender and age, causes of tooth avulsion, daily and
monthly distribution, type and number of avulsed teeth and the treatment procedures. Frequency
distribution and the chi-square test were calculated. The level of signifi cance was set at 5% for
all analyses. The highest incidence was found among boys (52.17%) aged 4 years (31.88%). The
main etiologic factors were falls (82.61%) and traffi c accidents (5.80%). Most cases occurred
during weekdays (82.61%), from March to June (autumn; n=28; 40.58%) and from September to
December (spring; n=18; 26.09%). Most avulsed teeth were maxillary central incisors (68.48%),
followed by maxillary lateral incisors (22.83%). The most frequent treatments were analysis of
clinical history and clinical exam (64 teeth; 69.57%) and space maintainer (18 teeth; 19.57%). The
epidemiological and clinical aspects of tooth avulsion in this study were similar to those reported
in other studies. There was a high number of avulsed primary teeth in boys aged less than 4 years
and caused by falls.
