Introduction: Cone beam computed tomography (CBCT) provides precise information on the patient’s anatomy, one of its most frequent indications being the evaluation of impacted and/or retained teeth. Maxillary canines are the most commonly retained/impacted teeth after third molars, making it essential to use tools that facilitate diagnosis, prognosis, and treatment planning. Objective: to present a protocol to characterize retained/impacted canines using TCHC. Materials and Methods: 188 CBCT examinations belonging to patients of both sexes aged 12-73 years were evaluated. Characteristics of depth, angulation, presentation, root state, degree of inclusion, relationship with adjacent structures and associated pathologies were identified. Results: Most of the patients (64.4%, n=121) were female. 147 canines (63.1%) were found to be impacted with deep retention. The retention angulation was classified mostly by mesioangular canines, representing 48.1% of the sample (n=112 ); Evaluating the presentation results, those located towards the palatal/lingual side predominated (45.9%, n=107). Regarding the root state, 183 canines (78.5%) presented complete rhizogenesis. The predominant degree of inclusion was subgingival in 174 canines (74.7%). When evaluating the alterations that these retained teeth caused in adjacent structures, it was found that 65.2% (n=152) of the sample did not generate any damage. Conclusions: the presented protocol allowed us to systematically assess and through specific parameters, the relationship of the retained/impacted canines with the adjacent dental units and anatomical structures of interest, which makes it possible to formulate a more appropriate diagnosis and therapy for the patient.
