Objective: this study aimed to evaluate the location and prevalence of maxillary canines included as well as the presence of root reabsorption on the adjacent teeth. Materials and method: 372 panoramic radiographs were examined from patients ranged from 13 up to 50 years old, performed among 2008 to 2013 in two dental schools. The radiographs were analysed by a single examiner, with the assistance of a magnifying and viewing box with a diameter of 90 mm and 2.5 times magnification. The data were statistically analysed by chi-square test (α = 5%). Results: It was found a total of 13 radiographs with the presence of upper canines included resulting in a prevalence of 3.5%. Age was a factor that statistically influenced the presence of canines included (p = 0.040), being more prevalent in patients of 13-30 years than in patients of 31-50 years old. The retention of canines was more prevalent in females, but without statistical significance (p = 0.163). The reabsorption of adjacent teeth occurred in 15.4% of cases. Conclusion: The prevalence of canine included was dependent of the age, which influenced the presence of canines included, and the mesiobuccal-angled position was predominant in all cases.
