68.有關enamel matrix derivative(Emdogain)的敘述,下列何者錯誤?
(A)Emdogain的主要成分是amelogenins
(B)它是疏水性,所以必須在酸性環境下才可以保持膠狀
(C)Emdogain能釋放生長因子,可促進人類牙周韌帶造纖維細胞癒合的速度
(D)Emdogain與骨移植材混合在骨下缺損治療,牙周附連獲得的效果在3-wall、2-wall和1-wall之間

(A) Enamel Matrix proteins, mainly amelogenin, are secreted by Hertwig’s epithelial root sheath during tooth development and induce acellular cementum formation.(p.974)
(B) 市面上 Emdogain 內含牙釉基質衍生物,其載體為 propylene glycol alginate,每毫升 6% propylene glycol alginate 含 30 毫克牙釉基質衍生物,pH 值 5.5,Emdogain 在低溫及低 pH 值下呈較黏稠狀,當其放置於口腔中溫度上升且被組織液中和後,牙釉基質衍生物便被釋放出來,對鄰近細胞產生作用。
(C) An in vitro wound-healing model demonstrated that the enamel matrix derivative enhanced human periodontal ligament fibroblast cell wound healing. (p975~976)
(D)無顯著差異
