Prevalence of impacted teeth and associated pathologies based on panoramic radiographs in Kosovar population

Tooth impaction is a frequent dental condition, often reported in the scientific literature. An impacted tooth is a tooth that fails to erupt into the dental arch within the expected time. There is considerable variation in the prevalence and distribution of impacted teeth in different regions of the maxilla and the mandible, also, the prevalence varies in different reports around the world. There are certain pathologies associated with tooth impaction. This research aimed to determine the prevalence of impacted teeth and associated pathologies, to determine commonly found impacted teeth and, also, to assess the pattern of impacted third molars and factors such as age, sex, angulation, type and depth of impaction in a Kosovar population. For this research, 5550 panoramic radiographs were analysed, which were randomly selected from the 15000 PANs obtained at the University Dentistry Clinical Center of Kosovo between 2011 and 2015. PANs were retrieved as digitalized images from the UDCCK database, exported to JPEG and subsequently analyzed with Corel Draw. During analysis, 'Magnify', 'Ruler' and 'Angulation' tools were used. The results of this study showed that the prevalence of impacted teeth in a total number of 5550 PAN samples was 17.6%, with no sex predilection, in the Kosovo population. They also showed no predisposition to maxilla or mandible, with highest frequency of impacted teeth in the groups from 18–30 years of age. In a total number of impacted teeth, third molars had the highest prevalence of 73.7%, with no sex and jaw predisposition. The mesio angular position was the most frequent one in almost all of the records (33.8%) and class C showed the highest frequency for depth of impaction (62.3%).Second most often impacted teeth in a Kosovar population were impacted canines with the prevalence of 21.0%, followed by premolars with the prevalence of 3.7%, incisors with the prevalence of 1.4% and impacted first and second molars with the prevalence of only 0.2%. The highest prevalence rates of pathologies were reported for root resorption of adjacent tooth (25.2 %), while increased coronal radiolucency had the lowest prevalence of pathologies of 1.1% and occurred only in impacted third molars.
