Abstract

Short root anomaly (SRA) is very rare, but can be problematic for physicians because patients with SRA are more vulnerable to root resorption with orthodontic forces. During the mixed dentition period, it may be difficult to diagnose generalized SRA. This article reports the treatment of an orthodontic patient with SRA at the early mixed dentition stage. Despite local tooth loss, a relatively favorable outcome was obtained without excessive root resorption. Ultimately, orthodontic therapy is possible for patients with generalized SRA, but precautions should be taken to avoid complications, such as tooth loss or root resorption.

Short root anomaly (SRA)는 매우 드문 질환으로, 교정력에 의한 치근흡수에 있어서 정상적인 치아보다 더 취약하므로 처치시에 어려움이 있다. 또한, 혼합치열기 시기에 나타나는 전반적인 SRA의 경우는 진단 또한 쉽지 않다. 초기 혼합치열기환아에서 방사선 사진만으로 전반적인 SRA를 예측하기 어렵지만, 가족력이나 관련 전신질환, 또는 구강 내 다른 치아이상(tooth anomaly) 등의 요소가 있는 경우, SRA를 염두에 두어야 한다. 본 증례는 전악에 걸쳐SRA를 보이는 초기 혼합치열기 환아의 교정적 처치를 다루었다. 비록 국소적인 치아 상실이 있었으나 적절한 교정적 배열을 통해 더 이상의 과도한 치근흡수 없이 치료를 마무리 하였으며, 비교적 양호한 치료 결과를 얻었기에 이를 보고하고자 한다. 결론적으로, SRA 환자에서도 교정 치료가 가능하며, SRA가 예측되는 혼합치열기 환아에서 치근 흡수나 치아상실과 같은 합병증이 나타나지 않도록 특히 주의를 기울여야 한다.
