Abstract
Objective: To estimate the incidence of maxillary canine impaction, its location, and mean impaction angle to the occlusal plane. Introduction: The canine teeth are important both aesthetically and functional occlusion. The maxillary canine impaction is genetically linked. Hence, the knowledge of prevalence in the local population is essential. Understanding the location of cuspid impaction is critical to initiate a preventive and therapeutic surgical or orthodontics interventions. Along with other clinical examinations, the impaction angle can also be used to differentiate the impaction location. Material and Methods: A total of 8517 patient's radiographs at the Dental Department of King Abdul Aziz Medical City, Riyadh, were retrospectively evaluated. The age group of the patient included in the study was between 18 and 45 years. The patient's records and radiographs were evaluated to register the impacted maxillary canines, location, and angulation to the occlusal plane. The obtained data were evaluated with SPSS 19 software to analyze the incidence and difference between the genders. Results: Total of 291 patients had the impacted maxillary cuspid. The additional radiograph was available with 44 patient records to further analyze the location of impaction. Among 44 patients, 17(38.64%) were males and 27(61.36%) female subjects. The seven (15.9%) of the cuspids were labially impacted, whereas 37(84.1%) were palatally impacted. The mean impaction angles for labial and palatal impactions were 57.65 and 65.4 degrees, respectively. Conclusions: The majority of canine impaction were palatally placed in comparison to labial impaction. The mean impaction angle of labial impaction is lesser than that of palatal impactions.
