Abstract: Maxillary canines are important aesthetically and functionally, but impacted canines are more difficult and time consuming to treat. Permanent maxillary canine impaction has been reported in about 1% to 5% of the population. The objective of this study was to determine the prevalence of impacted maxillary canine in patients visiting to Mayo Hospital Lahore. A total of 500 patients of 15 years and above were examined clinically. Those having maxillary canine impaction were advised Anterior Occlusal View and panoramic radiograph to determine the patterns of impaction by vertical parallaxing technique. Data were processed in SPSS version 16.0. The chi-squared test was used to reveal any differences in the distribution of impacted maxillary canines when stratified by gender and location (left or right). A p-value of less than 0.05 was accepted as statistically significant. Out of 500 patients examined 20(4%) had maxillary canine impaction. The mean age was 19.05±3.15 years. Age was ranged from 15 to 25 years. Female to male ratio was1.85:1. Females had more impaction of maxillary canine than males(p=0.000). Palatal were the most common in males while buccal were in females. Left side was commonly involved in impaction in both genders. Key Words: Impacted maxillary canine, patterns of impaction, vertical parallaxing technique.
