Abstract
The aim of this retrospective study was to investigate the prevalence and pattern of impacted teeth and associated pathologies in the Syrian Coastal population
Digital Panoramic radiographs of 2700 patients aged 25 years and above were examined. The radiographs were collected from radiography centers In the Syrian coastal area. The classification of impaction, caries and root resorption of the adjacent teeth and increase in the pericoronal space were determined.
A total of 584 (21.6%) patients presented with at least one impacted tooth. Among the 755 impacted teeth, mandibular third molars were the most common (62.8%), followed by maxillary third molars (29.9%), maxillary canines (4,5 %),and other teeth(1.45%).
The most common angulation of impaction was the vertical in the mandible and maxilla and the most common level of impaction was level B in the mandible and level C in the maxilla. Pathological conditions associated with impacted third molars were found in 21.1%. Caries was the most commonly seen lesion 9.4% of the distal surfaces of adjacent second molars, root resorbtion 7.6% and increase in the pericoronal space of the dental follicle of more than 3 mm was seen in 6.1% of impacted third molar.
The prevalence of impacted teeth was high, and there was no predilection for impacted third molars between sexes. Caries, root resorption and pericoronal lesions were seen in relation to the impacted teeth.
