陈旧性树脂%微拉伸强度
陳舊性樹脂%微拉伸彊度
진구성수지%미랍신강도
Aged composite Resin%Micro-tensile bond strength
目的：研究不同树脂与陈旧性树脂间的微拉伸强度差异。方法：制备可乐丽菲露 AP-X 树脂样本30例，浸泡于37℃蒸馏水1个月，表面经金刚砂车针研磨后随机分为3组：A 组涂布粘结剂后与可乐丽菲露 AP-X 新鲜树脂粘结；B 组涂布粘结剂后与3M Z250新鲜树脂粘结；C 组涂布粘结剂后与登士柏 TPH 新鲜树脂粘结。制备试件后，在万能材料试验机上测定材料间的微拉伸强度。结果：B 组微拉伸强度最大，C 组次之，A 组最小，3组间有显著性差异。结论：陈旧性树脂缺损的修复可以不要求使用同种树脂，使临床应用简洁化。
目的：研究不同樹脂與陳舊性樹脂間的微拉伸彊度差異。方法：製備可樂麗菲露 AP-X 樹脂樣本30例，浸泡于37℃蒸餾水1箇月，錶麵經金剛砂車針研磨後隨機分為3組：A 組塗佈粘結劑後與可樂麗菲露 AP-X 新鮮樹脂粘結；B 組塗佈粘結劑後與3M Z250新鮮樹脂粘結；C 組塗佈粘結劑後與登士柏 TPH 新鮮樹脂粘結。製備試件後，在萬能材料試驗機上測定材料間的微拉伸彊度。結果：B 組微拉伸彊度最大，C 組次之，A 組最小，3組間有顯著性差異。結論：陳舊性樹脂缺損的脩複可以不要求使用同種樹脂，使臨床應用簡潔化。

Objective:To determine the differences on the micro-tensile bond strength between different fresh and aged composite resin.Methods:Thirty composite resin specimens (Clearfil AP-X)were prepared.After being stored in distilled water at 37 ℃ for one month,composite surface was roughened with diamond bur and divided into three groups randomly,ten specimens in each group.In group A,ten specimens were used as substrate with adhesive to adhere fresh AP-X composite;fresh Z250 composite in group B;fresh TPH composite in group C.Specimens were then tested for the micro-tensile bond strength(μTBS)in a universal testing machine at a crosshead speed of 1 mm /min until failure.Results:μTBS of group B was the highest in the three groups.That of group C was second highest,and that of group A was the lowest.There were significant differences between three groups.Conclusions:In repairing aged composite resin,it is not necessary to use the same resin,which simplifies the clinical operation..
