66.關於冷凍乾燥異體移植骨（FDBA）與脫鈣冷凍乾燥異體移植骨（DFDBA）的敘述，下列何者正確？
(A)FDBA被認為具引導骨生成性質（osteoconduction），DFDBA則具誘導骨生成性質（osteoinduction）
(B)經過萃取過程，FDBA可釋放出BMP-2，DFDBA則無
(C)兩者均呈現不透射線性（radiopaque）
(D)使用來自皮質骨（cortical bone）的DFDBA所造成之骨內缺損填滿比例比來自髓質骨（cancellous bone）高

103-2-72. 下列有關同種異體骨移植體（allograft）的敘述何者正確？

(A)Allograft是在donor死亡後24小時內就要取出骨頭進行處理

(B)FDBA（freeze-dried bone allograft）有osteoinduction的效果比DFDBA（decalcified freeze-dried bone allograft）好

(C)FDBA會釋放出BMPs（bone morphogenetic proteins）

(D)臨床研究發現bone fill的效果，cortical DFDBA優於cancellous DFDBA ?

In 1975, Libin et al110 reported three patients with 4 to 10 mm

of bone regeneration in periodontal osseous defects. Subsequent

clinical studies were made with cancellous DFDBA and cortical

DFDBA.144,154 The latter resulted in more desirable results (2.4 mm

versus 1.38 mm of bone fill).

Subsequent clinical studies were made with cancellous DFDBA and

cortical DFDBA.221,230,233 DFDBA resulted in more desirable results
