Cone beam computed tomography (CBCT) is widely used for diagnosis and 
treatment planning in dentistry. Before being identified, CBCT scans of those 
impacted teeth can disclose traits. After the third molar, the tooth that is most often 
retained in the maxilla is the upper canine. The predominant adverse and 
detrimental consequence of maxillary canine impaction is the surrounding teeth's 
root resorption (RR), which results in severe damage and may even cause tooth 
loss. The impact of impacted maxillary canines (IMC) on root resorption of 
adjacent teeth was assessed in this narrative review by collecting several articles 
from a variety of sources, including manual cross-reference and textbook searches 
and electronic databases like PubMed, SCOPUS, COCHRANE library, and Science 
Direct. MeSH terms and keywords about root resorption, impacted maxillary 
canines, and cone beam computed tomography were used in the search. Following a 
comprehensive evaluation of the collected articles, fifty-three articles were chosen 
for this review.
