Abstract
Neuroblastoma is a common malignant tumor of the sympathetic nervous system in childhood, arises from embryonic neural crest cells. The period of tooth development is matched with peak times of diagnosis and treatment of neuroblastoma. The intensive multimodality treatment including radiotherapy and chemotherapy is used in patients with neuroblastoma has been shown to have late adverse effects and disturbances in dental development like tooth agenesis, microdontia, enamel hypoplasia and short roots. A 8-year old girl had been on medication and radiotherapy for neuroblastoma since she was 15 months old at Department Pediatrics, Chonnam National University Hospital. Oligodontia, microdontia, and short root formation was notable in clinical and radiological examination. Mobility of lower permanent incisor was detected and measured at about degree 2. Resin wire splint using mini-screw implantation on buccal alveolar bone was conducted for maintenance of mandibular incisors and alveolar bone. Excessive mobility has been eliminated and maintained well so far. Further treatment is planned for re-evaluation of mobility, preventing dental caries and regular oral hygiene management. Although we need further evaluation, this treatment could be one of alternative therapy for those who have similar dental anomalies.
다발성 우식증을 주소로 내원한 7세 1개월의 여자아이가 신경모세포종의 다각적 치료에 따른 치근 형성이상으로 인해 하악 영구절치의 중증도 동요도를 보여 mini-screw를 이용한 레진강선고정을 시행하였다. 이를 통해 동요도의 감소 및 교합안정을 이루었으며, 따라서 하악 영구절치의 치근 형성이상으로 인한 동요도 증가 시 선택적 치료법이 될 수 있을 것이라 생각한다.
