Aim: The present investigation aims to find out the prevalence of ectopic canines among skeletal class I, II, and III malocclusions and to evaluate its variability among different genders and their growth patterns. Material and methods: The study sample included orthopantomograms (OPGs), lateral skull views, and study models of 999 patients collected from departmental archives. Among the selected samples, 258 were males and 738 were females. They were divided into skeletal class I, II, and III malocclusions sagittally and hypodivergent, normodivergent, and hyperdivergent groups according to their angle formed between point A-Nasion – point B (ANB) and angle formed between the Sella-Nasion (SN) plane and Gonion (Go) – Gnathion (Gn) plane (SnGoGn) values respectively. Results: Of the 999 samples, 738 (73.9%) were female and 260 (25.8%) were male patients. When compared to men, females had a higher proportion of ectopic canines. An estimated 62.3% of skeletal class I, 29.1% of skeletal class II, and 8.6% of skeletal class III cases were found to have ectopic canines. An estimated 720 (72.1%) patients were found to have maxillary ectopic canines and out of the available sample, 474 patients have horizontal growth patterns, 335 have average growth patterns and 190 patients have vertical growth patterns. Labial impaction was the commonest (65.4%) followed by palatal (24.8%). Bilateral impaction was comparatively more (51.1%) than unilateral impaction (48.2%). Maxilla was more prevalent (72.1%) as compared to the mandible (16.3%) and for both the arches it was (11.6%). Ectopic canines were identified in a total of 62.3% of cases with skeletal class I, 29.1% of cases with skeletal class II, and 8.6% of cases with skeletal class III. Conclusion: The bilateral ectopic canine was mostly seen in skeletal class I and class III malocclusions, whereas, a unilateral presentation was mostly seen in skeletal class II malocclusions. Clinical significance: Knowing the likelihood of a maxillary canine erupting ectopically will aid clinicians in starting with interceptive therapy since this condition necessitates complex orthodontic mechanics.
