Maxillary canine erupts into the oral cavity through a long and tortuous course lateral to piriform fossa and takes the longest term for its development. The prevalence of impacted maxillary canines is 1-3%.If canine impaction is diagnosed early,the possibility of its prevention and treatment options becomes wider.The aim of the present investigation was to study in an orthodontic population if maxillary canine impaction subjects exhibit different prevalence in various skeletal malocclusion in the south Indian population.The lateral cephalogram of these 50 canine impaction cases were collected. The lateral cephalogram were sorted into the various skeletal malocclusion. ClassIII malocclusion defined as an ANB angle <0°, Beta angle of > 35°, Class I malocclusion defined as an ANB angle between 0° and 4°, Beta angle of 27°-35°, Class II malocclusion ANB angle >4°,Beta angle of <27°.Within the limitation of this study it can be concluded that prevalence of canine impaction cases among the various malocclusion were 40% skeletal class I malocclusion, 28% skeletal class II malocclusion 32% skeletal class III cases. No association between Skeletal malocclusion was found, confirming that skeletal malocclusion cannot be used as a diagnostic aid in determining the risk of maxillary canine impaction.
