The frequency was not significantly different between genders. Hypodontia was the most frequent anomaly with the incidence of 7.5%, followed by teeth impaction with the incidence of 6.3%.ConclusionThe distribution and the prevalence of anomalies were similar to those described in the general Croatian population.
