초록

Short root anomaly는 비정상적으로 짧고 뭉툭한 치근 형태를 가진 드문 질환이다. 대부분 상악 중절치에 대칭적으로 나타나며 영구치에서만 관찰되어 왔다. 이 증례는 9세 여환으로 혼합치열기에 짧은 치근 발달을 주소로 개인병원에서 의뢰되었다. 방사선 사진 및 구강 내 검사에서 법랑질 저형성증과 치내치와 같은 다른 치아이상과 함께 상악 및 하악 전치부와 하악 제 1대구치에서 SRA가 관찰되었다. 5년동안의 장기추적 관찰을 통해 환아의 모든 치아들은 혼합치열기에서 영구치열기로 변화하였고 모든 영구치에서 전반적인 SRA가 관찰되었다. 교정적 진단을 위해 촬영된 측면 두부 방사선 사진에서 치아 이상과 밀접한 관련이 있는 것으로 보고된 전방과 후방 상돌기 사이의 석회화인 sella turcica bridge 또한 관찰되었다. 이러한 여러 요소들을 통하여 치근 흡수나 치아 상실의 예방과 성공적인 관리 위해 SRA를 조기 진단하는 것은 매우 중요하다. 이 증례 보고에서는 다른 치아이상과 sella turcica bridge와 함께 전악에 걸쳐 나타난 전반적인 SRA를 보이는 환아를 장기적으로 관찰하고 의미있는 결과를 나타내고 있기에 이를 보고하는 바이다.

Short root anomaly (SRA) is a rare dental condition with abnormally short and blunt root morphology. It mostly affects maxillary central incisors symmetrically and only has been observed in permanent teeth. A 9-year-old girl was referred from a local dental clinic for short root development in mixed dentition with no symptoms. Radiographic and intraoral examinations revealed SRA on upper and lower incisors and mandibular first molars along with other dental anomalies such as enamel hypoplasia and dens invaginatus. During long - term follow - up for 5 years, her mixed dentition has changed to permanent dentition and generalized SRA was observed in all permanent teeth. Cephalometric radiograph also revealed the calcification between the anterior and posterior clinoid processes described as a sella turcica bridge which was reported associating with dental anomalies. Early diagnosis of SRA is emphasized for successful management and prevention of root resorption and tooth loss. This report aimed to present a rare case of generalized SRA along with other dental anomalies and sella turcica bridging in a female patient through long - term follow - up.
