Abstract
Background: External apical root resorption (EARR) is an
iatrogenic sequence of orthodontic treatment. The prevalence of
EARR is dissimilar among racial groups. There is an increase in
orthodontic treatment demand among the Sudanese population with
no information about the prevalence of EARR.
Design: This is a clinical, retrospective study.
Setting: The study was done among patients attending the
orthodontic clinic at the University of Khartoum, Faculty of
Dentistry as well as one private clinic in Khartoum.
Objectives: To evaluate the prevalence of EARR in a Sudanese
sample as well as factors related to root resorption before (T1) and
after (T2) orthodontic treatment.
Methods: Fifty one patients (41 females and 10 males), mean age
21.6±6.9 years, who have been treated using pre-adjusted edgewise
appliances for at least one year.
The prevalence of EARR, and the relationship between EARR at T1
and T2 with regard to sex, age, extraction and treatment duration was
investigated.
vi
Results: The overall prevalence of EARR at T2 was 14% of that,
mild EARR was 43%, whereas moderate and severe EARR were
10% and 2% respectively. No statistically significant relationship
was found between EARR and sex, age or treatment duration at P>
0.05. A statistically significant correlation was found between EARR
and extraction of at least two permanent teeth at T2 (P<0.04).
Conclusion: There was a high prevalence of EARR in the studied
sample; only the extraction pattern seems to correlate with EARR in
this sample of Sudanese patients.
