Abstract

This study was aimed to retrospectively evaluate the clinical findings and treatments of odontomas in the Korean demographic group. The subject of the present study included 75 odontomas in 74 patients who received treatment from Chonbuk National University Dental Hospital between April 2005 and March 2014. The average age of the subjects were 10.3 years old (range 3 - 23 years old). 42 (56.8%) males and 32 (43.2%) females were in the present study. It was found that compound odontomas were about 4 times more common than complex odontomas. Odontomas equally occurred in both maxillary and mandible. The impaction of permanent teeth (73.3%) was the most common complication of odontomas on adjacent teeth. Most odontomas (96.0%) were surgically removed either to induce spontaneous eruption or to guide orthodontically to occlusion. When the impacted tooth could not be naturally or forcefully erupted to occlusion, it was extracted. Early detection and treatment of odontomas would increase the possible preservation of the impacted tooth by eliminating the source of disturbance. Therefore, this study recommends that periodic radiographic examination from birth until the eruption of the permanent third molar to prevent possible hindrance to the teeth eruption.

치아종은 상피성 치성 종양에 속하며 악골내 치성 종양 중에서 가장 흔한 질환으로 보통 유치의 만기 잔존이나 영구치의 매복과 연관되어 나타난다. 본 연구는 2005년 1월부터 2014년 3월까지 전북대학교 치과병원에서 치아종으로 진단을 받은 74명의 환자에서 발견된 치아종 75증례를 분석하였다. 그 결과 남자가 42명(56.8%), 여자 32명(43.2%)으로 남자에서 약 1.3배 정도 높은 발생률을 보였다. 치아종으로 진단받은 환자들의 평균 나이는 10.3세이며, 치아종의 위치는 상악 48%(36개), 하악 52%(39개)로 균등하게 분포되어 있었다. 치아종과 관련된 임상 증상으로는 인접 치아의 매복 76%, 유치의 만기 잔존 52%, 인접 치아들의 전위 또는 회전이 32%로 나타났다. 치아종은 대부분 외과적으로 제거되었으며, 제거 후 자발적으로 맹출한 경우가 17증례, 영구치 맹출을 위해 추가적 치료가 필요했던 경우가 25증례, 매복된 치아의 예후가 불량할 것으로 판단되어 발치를 한 경우가 9증례였다.
