Abstract:
Objective To characterize the epidemiological,radiographic and clinical features of transmigrated mandibular canines by cone-beam CT(CBCT),in order to provide assistance for treatment planning.Methods Patients treated at our institution diagnosed with mandibular canines transmigration were retrospectively screened using CBCT images from June 2012 to December 2018.Clinical and radiographic parameters including location,classification,neighbouring structures,and associated anomalies were evaluated.Re-sults Eighty-two patients with 85 transmigrated mandibular canines were enrolled,establishing a prevalence of 0.11％(82/75 021).Among these cases,79 patients had unilateral transmigration of mandibular canines;the other 3 had bilateral transmigrations.Thirty-nine cases were male and 43 were female,with age ranging from 10 to 58.According to the Mupparapu classification,type Ⅰ(42,49.41％)was the most prevalent followed by type Ⅱ(19,22.35％)and type Ⅲ(15,17.65％).Fifty-three(62.35％)crowns were located labially,and often associated with odontoma,cyst and supernumerary tooth.Seventy transmigrated canines were surgically re-moved while 2 cases were tried to orthodontically aligned,failed and finally extracted.Ten cases received routine monitoring.Conclu-sion The transmigration of mandibular canines is rarely occurring abnormality with certain clinical imaging features which can assist in clinical diagnosis and treatment planning.
