ABSTRACT

Impacted teeth are teeth with a delayed eruption time or that are expected to erupt incompletely. Those teethcan cause a series of potential problems such as root displacement and resorption, periodontal problems in adjacentteeth, referred pain and the formation of cysts and odontogenic tumors. The purpose of this study was toinvestigate characteristics and treatment of child and adolescent patients younger than 15 years of age thatwere diagnosed with an impacted tooth who visited the Chosun University Dental Hospital. The impacted tooth, its etiology, treatment and traction period were surveyed through electric medical records,radiographs in 335 patients. We excluded the impacted third molar, supernumerary and deciduous teeth fromthis study. The most frequently impacted teeth are upper canine, followed by the upper incisor. The most commonetiologies of impaction were an abnormal eruption pathway and localized pathologic lesions. The treatment of animpacted tooth was mostly orthodontic traction. The traction period was relatively short in cases with distinctobstacles, with an impacted upper incisor and if patients were younger. An orthodontic traction is considered to be more unfavorable if the patient gets older. Therefore, an earlydiagnosis and a precise treatment plan through a regular check-ups are mandatory.
