科普:杜牙根嘅步驟
杜牙根系通過清除根管內嘅壞死物質,進行適當嘅消毒、填充根管,以去除根管內容物對根尖周圍組織嘅不良刺激,防止發生根尖周病變或促進根尖周病變癒合嘅一種治療方法。咁,杜牙根嘅步驟系乜?



杜牙根嘅步驟系乜?杜牙根嘅操作比較複雜,器械繁多而精細,治療時間長,一般包括以下四個步驟:



杜牙根嘅步驟1:根管預備:



開髓,徹底清除病變壞死嘅牙髓組織,再測量根管長度,做根管擴大。



杜牙根嘅步驟2:根管沖洗



喺杜牙根中需要反復操作,將根管內有機物嘅細小碎片和切削掉嘅硬組織細小碎末等感染源沖洗乾淨。



杜牙根嘅步驟



杜牙根嘅步驟3:根管消毒



藥物消毒系最常用嘅,用棉撚蘸些小藥液置於根管內,洞口用暫封材料密封。



杜牙根嘅步驟4:根管填充:



呢個系杜牙根中最重要嘅步驟,常用根管充填劑加用牙膠尖充填根管,使根管系統能嚴密封閉。



做完杜牙根之後,一般都系建議做個牙冠嘅,因為杜牙根後嘅牙齒會變得脆弱,容易折斷、劈裂。



以上就系「科普:杜牙根嘅步驟」嘅具體介紹,希望對大家有所幫助。
