Management of a Traumatic Injured Immature Maxillary Incisor by Cvek Pulpotomy : A Case Report
以Cvek斷髓術治療受撞擊而露髓之未成熟恆門齒：病例報告
摘要
牙齒外傷常發生於孩童在遊玩或運動期間。治療受撞擊之發育未成熟且伴隨牙髓暴露的恆齒時，應著重於保留牙髓活性，並促使牙齒及牙根繼續發育完全。Cvek斷髓術是一種以保守性移除牙髓暴露點下兩公厘之牙髓組織，並放置三氧礦化物（MTA）或氫氧化鈣等生物相容性材料的治療方式，可促使牙本質橋（dentinal bridge）生成及牙根持續發育。本病例為一九歲男童之恆門齒受撞擊後牙髓暴露，在兩天後以Cvek斷髓術與三氧礦化物治療。經歷二十八個月追蹤，臨床上無症狀，X光片亦顯示牙根持續發育完全，而且牙齒對電器測髓恢復反應。因此Cvek斷髓術對於外傷引起牙冠折斷牙髓暴露的未成熟恆齒是可行且適當的治療技術。
並列摘要
Cvek pulpotomy is a conservative vital pulp therapy that consists of removing approximately 2 mm inflamed coronal pulp and placing biocompatible material over the underlying pulp tissue. This technique is suitable for treating traumatic injured immature teeth with pulp exposure. This case report presents a 9 year-old boy suffered from complicated crown fracture on tooth #11 two days ago and received Cvek pulpotomy with MTA dressing. Two mm of coronal pulp tissue from the exposure site was surgically removed, followed with normal saline irrigation and 2.5% NaOCl cotton pellets hemostais for 1 minute. Gray MTA was placed over the pulp stump, and GIC was then used for coronal seal. After 28 months follow-up, clinically no symptoms and signs were observed. Periapical x-ray revealed complete root formation, and electric pulp test (EPT) showed positive response.
