Aim: The current research was to estimate the prevalence of impacted canines among the Egyptian population; the following parameters were included as sex, age, number, position, laterality and associated pathology with impacted Canine.What is the prevalence of impacted Canine among orthodontic clinics in the Egyptian population? Additionally to correlates between peg-shaped lateral teeth and missing the second premolar in different levels of each quadrant. Methodology: Panoramic radiographs were recruited from the orthodontic department clinics in multiple universities in Egypt (Cairo, Ain shams, Alexandria, and Al-Azhar University).Complete orthodontic records, including radiographs, of 3560 patients who sought malocclusion treatment between April 2020 and September 2020 were retrieved for this study; after filtration of these panoramic radiographs,184 radiographs were included in the study that fulfilled the lasted criteria. Results: After filtration of these panoramic radiographs,184 panoramics were included in this study; at least one impacted canine teeth was noted in 5.28% of patients. Most common impacted canine teeth in the maxilla (84.4%) and the mandibular (15.5%). In gender, males (35.1%), while females (64.9%).The comparison revealed an insignificant difference between percentages with the same superscript letters (right & left side maxillary canine- right & left side mandibular Canine).A weak correlation was found between impacted canine and missed wisdom, missed the second premolar, and peg-shaped lateral incisor
