摘要

本病例報告為一名十二歲腦性麻痺的男孩，因中心咬頭斷裂導致牙根尚未成熟的下顎第二小臼齒牙髓壞死及根尖周圍炎。我們使用保守性治療，未使用根管挫針作根管內清創，而以次氯酸鈉沖洗搭配氫氧化鈣放置，最後以MTA充填，成功改善臨床症狀，且術後可見牙根持續生成，根尖也有逐漸關閉的情況。

This case report describes a twelve-year old boy with cerebral palsy had his right mandibular second premolar pulp necrotic due to central cusp fracture. The periradicular diagnosis was symptomatic periradicular periodontitis. Instead of intra-canal instrumentation, intra-canal irrigation with sodium hypochlorite, calcium hydroxide medication and filling with MTA were performed. After 6 months, continued development and formation of the root were observed through the periapical radiograph. This case report indicates a more conservative approach may be preferable to traditional Apexification when treating pulp necrotic immature teeth.
