Objective: To determine the incidence of impacted maxillary canine in Ramadi city and evaluate the existing relation between impaction of upper canine and anomalies of maxillary lateral incisors. Materials and methods: Forty five patients with impacted maxillary canines the data take from the patients include sex, age, the status of missing permanent maxillary canines, side, number of impacted maxillary canines, anomalies in lateral incisor, and molar classification in addition of that take panoramic radiographic for each patient have impacted canine and examined the angulation, depth of the impactions and the present of the external apical root resorption in neighboring lateral incisor. Results: The frequency of impacted canines in our study was 4.6%, a male to female ratio of 1:2. Right canine impaction 51.1%, left side impaction 37.7% and bilateral impaction 11.11% cases. 39% of cases are buccally impacted and 61% of cases are palataly impacted. The impacted maxillary canine have a significant correlation p<0.05 with anomalies in lateral incisor or external apical root resorption. The patients have class I the higher percentage of impacted maxillary canine follow by class II division 2 then class II division 1 and the last one is class III patients. Conclusion: The frequency of impacted canines in our study was 4.6%, higher than most other studies, it was found that unilateral impaction is much more common than bilateral impaction. There was a clear association between impacted canine and a missing or anomalous lateral incisor on the affected side. Impaction canine occurred most frequently in patients with a Class I malocclusion and less in class III malocclusion.
