| Summary: | <strong>Introduction:</strong> Impaction may be defined as the failure of complete eruption into a normal functional position of one tooth within normal time due to lack of space in the dental arch, caused by obstruction by<br />another tooth or development in an abnormal position. The mandibular third molar is the most frequently impacted tooth. The incidence varies from 9.5% to 68% in different populations.<br /><strong>Methods:</strong> The study was conducted in Department of Oral Surgery, Faculty of Dentistry, University in Sarajevo. Study represents retrospective analysis of panoramic radiographs (orthopantomograms) of patients<br />referred to Department of Oral Surgery from January 2010 to February 2013 with indication for surgical removal of impacted third molars.<br /><strong>Results:</strong> Of the 2000 radiographs, 761 presented with at least one impacted third molar (38%). A total of 1034 impacted mandibular third molars were present (51.7%). The most common age group was third<br />decade (61.2%). Signifi cant statistical difference in incidence of third molar impaction was found between females and males (p<0.05), but there was no statistical difference in incidence in urban and suburban<br />population (p=0.374). Vertical angulation was the most common pattern of impaction (65%). Frequency of third molars erupted into their normal position (class IA) was 42%. Impacted mandibular molars were<br />associated with periodontal pockets in 134 (6.5%) cases and with dentigerous cysts in 5 cases (0.2%).<br /><strong>Conclusion: </strong>The present study provides useful data regarding the clinical status of third molars in population of Bosnia and Herzegovina. |
