This study performs a clinical, radiological and statistical evaluation of permanent teeth impaction on a sample of young patients from the North-eastern region of Romania. 67 orthodontic patients (29 boys and 38 girls), aged 6-37 years, were selected randomly during 1991-2010. Data from orthodontic records were evaluated according to social parameters, oral status, etiological causes, clinical features and treatment options. Statistical evaluation was done with the SPSS 20.0 package. The cuspid impaction was most frequent in girls (68.40%) and in boys was the central incisor impaction (55.20%). The most common was the single tooth impaction in upper arch (85.10%) and the severe impaction (76.10%). We found statistically correlations between the direction and localization of impaction and types of impacted teeth (p=0.002). 4.14:1 ratio was established between the conservative and the radical treatment. The risk factors (OR=1-5) and predictors for the extraction of impacted teeth (HL test, p=0.000) were identified.
