Aim of the study. To analyze dental anomalies
(agenesis, supernumerary teeth, microdontia,
transposition, impaction, taurodontism, dilacerations,
enamel hypoplasia, dens evaginatus and dens
invaginatus) in orthodontic subjects. Material and
method. Pretreatment clinical and radiographic
records of 379 orthodontic subjects were studied.
Results. 22.2% of patients presented at least one dental
anomaly. The prevalence in females was statistically
significant (chi squared test, p<0.05) compared to
males. Conclusions. Congenitally absent teeth and the
presence of impacted teeth were the most frequently
observed abnormalities. Orthodontic planning and
treatment could be improved by bearing in mind the
presence of dental anomalies and the relationships
between them.
