Introduction:The exact location and early detection of impacted maxillary canines plays a very key role in the orthodontic treatment planning. The aim of the present review wasto compare the diagnostic effectiveness and accuracy of CBCT with that of conventional radiography in the localization of impacted maxillary canines.

Method:  Observational  studies published between January 1, 2011, and December 1, 2017, were identified from PubMed–MEDLINE, the Cochrane library, IndMed, Google Scholar and major journals. Modified MINORS checklist was applied to assess the quality of studies.

Result: The preliminary screening consisted of 34 articles, of which 8 articles that met the inclusion and exclusion criteria were selected. All authors agreed that CBCT was more reliable and resulted in higher accuracy in localization of impacted maxillary canine.Out of 8 included studies 6 were moderate to high quality and only 2 studies were of low quality.

Conclusion:The use of CBCT  is  advantageous in treatment planning for impacted canines by providing accurate localization and facilitating understanding of the anatomic relationships between the impacted tooth and the adjacent roots. CBCT overall helped in increasing the confidence level of the clinician regarding the treatment planning.
