Abstract

Odontoma represents 22% of all odontogenic tumors, which is characterized by slow growth pattern. Most of the odontomas usually develop during dental follicle proliferation. The growth of odontoma is limited and lesion is generally asymptomatic. It is frequently diagnosed during assessments for delayed eruption of permanent tooth and is usually founded in the second decade of life. Odontoma is usually diagnosed through radiographic views and is difficult to diagnose at the early developmental stage of odontoma. But an uncalcified developing odontoma can disturb the eruption of the tooth, so it is important to perform periodic radiographic examinations. Treatments are surgical removal and observation of odontoma followed by surgical opening or orthodontic traction of impacted tooth according to the tooth development and the location of impacted tooth. In this case, we found the radiopaque calcified odontoma in the radiographic view meanwhile follow up of the impacted tooth showing idiopathic eruption disturbance. This suggests that a developing odontoma is the cause of eruption disturbace.

치아종은 느린 성장을 나타내는 양성종양으로 치성종양의 약 22%를 차지한다. 대부분 치아발생 과정 중 치배증식기에 시작되며, 성장이 제한적이고 특별한 임상 증상을 나타내지 않기 때문에 환자가 자각할 수 없는 경우가 많다. 치아 맹출 장애를 주소로 이를 확인하는 과정 중에 흔히 진단되며, 10대에 가장 많이 발견된다. 치아종은 주로 방사선 사진을 통해 진단되는데, 발생 초기 및 초기 석회화 단계에서는 방사선 사진에서 확인하기 힘든 경우가 많다. 그러나 석회화되지 않은 치아종도 치아의 맹출을 방해할 수 있으므로 정기적인 방사선 사진 촬영을 통한 확인이 필요하다. 치아종에 의해 맹출 장애가 발생한 경우 매복치의 발육정도와 매복위치에 따라 치아종을 제거한 후 자발적 맹출을 기대해 보거나 매복치의 외과적 노출, 교정적인 견인 등의 방법을 고려할 수 있다. 본 증례는 특별한 원인 없이 맹출 장애를 보여 정기검사 또는 매복치의 맹출 유도를 위한 치료도중, 치아종이 석회화된 후에 방사선사진 상에 관찰되어, 맹출 장애 원인이 발육중인 치아종에 의해 야기되었음을 확인하여 이에 보고하는 바이다.
