Prevalence and distribution of impacted canines: a retrospective cross-sectional study

Background: This study aimed to determine the distribution and position of impacted canines among patients at the School of Dental Medicine, University of Nevada Las Vegas. Methods: A retrospective keyword search of clinical notes in AxiUm™ identified cases with impacted canines among patients aged ≥12 years seen between 2014 and 2022. Demographic data were analyzed using a Chi-square test against Clark County’s population demographics. Results: A total of 104 patients had impacted canines, with 69.2% being female and 30.8% male. The most affected ethnic groups were mixed (44%), Hispanic (25.96%), Caucasian (18.27%), African American (9.62%) and Asian (1.92%). The most common impaction was tooth #6 (64.42%). Conclusions: Among maxillary canine impactions, Type II accounted for 48.6%. The findings suggest a higher prevalence of impacted canines among females, Hispanic and mixed-ethnicity patients, with maxillary canines most commonly affected.
