INCIDENCE OFMANDIBULAR CANINE IMPACTION AND TRANSMIGRATION: A RETROSPECTIVE STUDY

26194

Objective: In human dentition, maxillary and mandibular canines are important from an esthetic as well as a functional point of view when they are present in their normal position. Although the maxillary permanent canine is frequently misplaced, failure of eruption of the mandibular canine is an unusual event. The aim of this study was to determine the incidence of impacted mandibular canines and transmigrated mandibular canines and associated pathologies. Material andMethod: Panoramic radiographs and clinical records of 7753 patients (4573 females and 3180 males) who referred to our Oral and Maxillofacial Surgery Department from January 2000 to December 2009 were evaluated. Position, location, side and classification of impacted canines, any associated pathologies due to impaction and age of patients were evaluated. Results: Fiftynine impacted mandibular canines in 54 patients (29 females and 25 males) and 14 transmigrated canines in 13 patients (8 female and 5 male) were found on 7753 radiographs. It was determined that 2 of 59 canines associated with odontoma and one of these canines was associated with cyst formation. According to clinical records, 30 impacted mandibular canines were extracted due to odontoma, cyst formation, pain, patients’ demand or prophylactic reasons. The remaining 29 mandibular canines were followed up. It was found that the number of persisted primary mandibular canines was 21. Conclusion: In this study, the incidence of impacted mandibular canines was 0.70 %. The study indicates that the impacted mandibular canines were most frequently in vertical position, then in mesioangular position. The incidence of transmigrated canines was found 0.17 % in this study.
