Aim: To determine the association of impacted maxillary canines with other developmental dental anomalies and compare them with a control population and to compare palatally and labially impacted canine associated anomalies. Methods and Materials: Ninety non-syndromic orthodontic patients from a south Indian population, with either labial or palatal impactions of one or both maxillary canine teeth, were selected for the study group. A group of 250 patients who had normally erupted maxillary canines were selected as controls. Clinical findings and panoramic radiographs were used to identify dental anomalies. Results: Prevalence of premolar rotation was found to be 80% in the study group followed by canine rotation (20%), taurodontism (26.6%), infraocclusion of premolars (25.5%), impacted mandibular canine (11.1%), and peg lateral (7.7%). Forty-nine (54.4%) palatally impacted, 37 (41.1%) labially impacted, and 4 (4.4%) centrally impacted canines were also observed. Of the 250 subjects in the control group 78.8% presented with premolar rotation. Maxillary canine transmigration, infraocclusion of premolars, anomalies of maxillary lateral incisors, and taurodontism showed significant associations with palatally impacted canines (P<0.05). Conclusion: The present study illustrates a significant association of anomalous maxillary lateral, anomalous mandibular canine, taurodontism, infra occlusion of premolar, over retained deciduous molar, and maxillary
