Abstract

Computed tomography(CT) has become more widely available in recent years and is recognized as an important diagnostic tool for complex disease and condition of the orofacial structure in adults. In pediatric patients, especially in the mixed dentition period, the number of superimposing dental structures in the jaw bone is much greater than in the permanant dentition period. Therefore, in spite of radiation risk, computed tomography should sometimes be used in pediatric patients in order to obtain a precise and valid diagnosis. This case study presents clinical application of computed tomography on patients visiting department of pediatric dentistry in Seoul National University Dental Hospital. The results obtained through these cases were summarized as follow : 1. Localization of impacted teeth using CT allows for efficient treatment planning leading to reduced postoperative complications. 2. In orthodontic traction of impacted permanent teeth, utilization of CT made exact localization of window site and determination of prognosis possible. 3. Use of CT made possible definite diagnosis of lesions in the jaw that were only suspected on plain film radiographs. 4. Careful selection is necessary when applying CT on children due to increased radiation dose and high cost.

1. CT에 의한 매복치의 위치결정은 적절한 치료계획의 수립을 가능하게 하여 시술시간의 단축과 인접치, 인접구조물의 손상을 줄여 시술후의 부작용을 줄일 수 있었다. 2. 매복된 영구치의 견인시 CR를 활용한 결과 개창부위의 정확한 위치결정과 예후에 대한 예측이 가능하였다. 3. 평면방사선사진의 판독후 악골내 병소가 의심되어 CT를 활용한 결과 병소의 확진이 가능하였다. 4. 소아의 CT촬영은 평면 방사선 촬영에 비해 증가된 방사선 피폭량, 높은 수가 때문에 적절한 증례의 선택이 중요하다.
