Abstract

Impacted teeth are teeth with a delayed eruption time or that are expected to erupt incompletely. Those teeth can cause a series of potential problems such as root displacement and resorption, periodontal problems in adjacent teeth, referred pain and the formation of cysts and odontogenic tumors. The purpose of this study was to investigate characteristics and treatment of child and adolescent patients younger than 15 years of age that were 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 from this study. The most frequently impacted teeth are upper canine, followed by the upper incisor. The most common etiologies of impaction were an abnormal eruption pathway and localized pathologic lesions. The treatment of an impacted tooth was mostly orthodontic traction. The traction period was relatively short in cases with distinct obstacles, 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 early diagnosis and a precise treatment plan through a regular check-ups are mandatory.

매복치란 맹출 연령임에도 맹출이 되지 않았거나, 임상적, 방사선학적 관찰을 통해 완전한 맹출이 어려울 것으로 예상되는 치아이다. 매복치는 치근 변위와 흡수, 인접치의 치주적 문제, 재발성 통증, 낭종의 형성과 같은 잠재적인 문제의 원인이 될 수 있으며, 상악 전치부의 경우 심미적인 문제를 야기 할 수 있다. 이 연구는 조선대학교 치과 병원에 내원하여 매복치로 진단 받은 15세 이하의 소아 청소년 환자의 매복치 특성과 치료에 대해 분석해 보기 위해 시행되었다. 매복 제3대구치, 매복 과잉치, 매복 유치를 제외한 335명의 환자를 대상으로 한명의 조사자가 환자의 전자 차트 기록과 파노라마 방사선 사진, 치근단 방사선 사진을 통해 매복치아의 위치, 매목의 원인, 치료방법, 견인치료 기간 등을 조사 하였다. 매복의 빈도는 다음과 같았다 : 상악 견치, 상악 절치, 하악 소구치, 상악 소구치, 하악 견치. 치아 매복의 원인으로는 치배 위치나 맹출 경로 이상(38.04%), 국소적 병소의 존재(35.01%)가 대부분을 차지하였다. 매복치의 치료로는 교정적 견인(46.01%)가 가장 많았다. 국소적 병소 같은 명확한 방해요인이 있는 경우 견인 기간이 상대적으로 짧게 나타났으며, 상악 절치의 경우가 매복 상악 견치보다 짧은 견인기간이 관찰되었다. 본 연구에서, 교정적 견인의 성공률은 96.7%였으며, 5증례가 실패하였다. 3증례는 장치협조도 불량으로 인한 것 이었으며, 2증례는 치아 유착으로 인한 실패였다. 매복치의 견인은 연령이 증가 할수록 불리할 것으로 여겨진다. 따라서, 정기적 검진을 통한 조기의 진단과 적절한 치료계획이 매우 중요하다. 또한, 소아 청소년 환자의 성공적인 교정적 견인 치료를 위해서는 환아의 협조도가 특히 중요할 것으로 생각된다.
