ABSTRACT: The maxillary permanent canines are the second most common impacted teeth after the third molars. Nevertheless, the degree to which clinicians are aware of the risk of canine impaction in each skeletal pattern may help them prevent these impactions or manage them. The present study determined the skeletal characteristics of the patients with the buccal and palatal impacted permanent canines among Ahvaz populations.In a descriptive epidemiologic study, lateral cephalometric and panoramic radiographs of 110 patients with the permanent impacted canines (bilateral or unilateral) were collected from the Orthodontic Department and orthodontic offices in the city of Ahvaz. Using cephalometric and panoramic images, and by clinical evaluations, buccal and palatal impacted canines were diagnosed. Cephalometric analysis was done to determine the anterior-posterior parameters including the angle of maxilla to the skull base (SNA), the angle of the mandible to the skull base (SNB), SNA angle and SNB angle difference (ANB) and the indices to determine the vertical characteristics including the angle between the Frankfurt plane and mandibular plane (FMA); Anterior lower facial height index and Jaraback index was calculated. According to the data obtained, anterior- posterior and the vertical skeletal patterns were determined for the patients by gender. The frequency of different patterns was calculated and then reported. Among those patients who have buccal canine impactions, females with Cl II skeletal pattern and long-face had the most frequencies, whereas the males with the Cl II skeletal pattern and normal face and also the males with the Cl III skeletal pattern and three vertical patterns had the least prevalence. In patients with the maxillary palatal canine impactions, female population with the Cl I skeletal and short-face pattern had the most frequency and the subjects with Cl III skeletal pattern showed the least prevalence. What could be concluded is that various facial morphologies were observed in both male and female populations of Ahvaz having permanent buccal and palatal impacted maxillary canines.
