- Abstract -

Aim and objectives. The aim of this study was to investigate the prevalence of hypodontia in permanent dentition, among patients who were treated in our Department of Pedodontics-Orthodontics of University of Medicine and Pharmacy in Timisoara.

Material and methods. In order to analyze the prevalence of hypodontia, we examined orthodontic files of 1350 patients, which included orthopantomograms, study models and anamnestic data. Patients with cleft lip/palate or having tooth loss due to dental caries, periodontal disease, traumas, and congenitally missing third molars were excluded from this study.
Results. The prevalence of hypodontia was 6.47% excluding third molars.The most frequently missing teeth were the maxillary lateral incisors, followed by the mandibular and maxillary second premolars.

Conclusions. Prevalence of hypodontia found in this sample of orthodontically treated patients was within the wide range reported in the literature for a normal population.

Key words: Hypodontia, congenitally missing teeth, prevalence
