中文摘要 | 外傷常造成牙齒結構的損傷,相對其他牙齒傷害,水平牙根斷裂的發生率較低,但常因伴 隨牙周組織的破壞,造成治療上的困難。一位八歲六個月大的女孩,就診前三天前跌倒,右上正 中門齒嚴重脫位,有三級的搖動度,牙齒已在診所接受根管緊急治療,根尖X光片顯示牙根中間 有水平斷裂。首先將牙齒復位並做固定,接著對牙根冠部進行根管治療,放置氫氧化鈣;十一個 月後,牙根斷裂處有硬組織形成,於是使用MTA做根管充填,並以複合樹脂復形。兩年兩個月 的追蹤,右上正中門齒動搖度正常,且並沒有症狀。此案例顯示,水平牙根斷裂合併嚴重牙齒脫 位,經過適當處置,牙齒得以保存與癒合。 |
英文摘要 | Dental trauma often leads to tooth structure being damage. When compared to the other types of dental trauma, horizontal root fracture has a lower incidence; however they may be accompanied with periodontal destruction and poorer prognosis. This report presents an eight and half year-old girl who suffers from dental trauma. Upon physical examination, her right central maxillary incisor was noted with severe luxation and grade III mobility. The tooth had received emergency endodontic treatment in local dental clinic. Periapical X-ray film illustrated a horizontal fracture line at the middle third aspect of the root. After examination, tooth was repositioned and splinted with composite resin. The tooth was then root canal treated with Ca(OH)2 as intracanal medicament in the coronal part of root. At the 11-month recall, hard tissue formation was noted at the fracture site. The root canal was filled with MTA. At the 2-year-2-month recall, patient remained symptom free when performing normal function. |
