【摘要】：目的:比較3種自酸蝕粘結(jié)劑與3種樹脂對牙齒V類洞的微滲漏的影響。方法:在45顆新鮮拔除的第三磨牙的頰舌側(cè)頸部制備箱狀(3mm×2mm×2mm)V類洞。按隨機數(shù)字法分為9組,每組有5顆牙齒,10個洞。有如下組合:A+D組(Easy one+Z350)、A+E組(Easy one+AP-X)、A+F組(Easy one+TPH)、B+D組(S3+Z350)、B+E組(S3+AP-X)、B+F組(S3+TPH)、C+D組(XV+Z350)、C+E組(XV+AP-X)、C+F組(XV+TPH)。按各粘結(jié)劑與復(fù)合樹脂說明書方法,對每組洞進行相應(yīng)的粘結(jié)劑和樹脂充填。將牙放在37℃恒溫水浴箱24h后,室溫下浸泡于1%的亞甲基藍24h,然后用金剛砂片將牙齒頰舌向切開為兩半,在體式顯微鏡下觀察微漏程度。結(jié)果:粘結(jié)劑S3bond與不同樹脂配伍使用時,其微滲漏存在顯著性差異(P0.05);粘結(jié)劑Easy one、Xeno V與不同樹脂配伍使用時,其微滲漏不存在顯著性差異;樹脂Z350、可樂麗菲露AP-X與不同粘結(jié)劑配伍使用時,其結(jié)果存在顯著性差異(P0.05);樹脂TPH與不同粘結(jié)劑使用時,其結(jié)果不存在顯著性差異。結(jié)論:微滲漏的發(fā)生是粘結(jié)劑與樹脂共同作用的結(jié)果。在臨床用粘結(jié)劑與復(fù)合樹脂修復(fù)V類洞時,應(yīng)考慮其配伍性。
[Abstract]:Aim: to compare the effects of three self-etching binders and three resins on the microleakage of V-cavity in teeth. Methods: box-shaped cavities of 3 mm 脳 2mm 脳 2mm)V were prepared in the buccal and lingual neck of 45 freshly extracted third molars. They were divided into 9 groups according to random number method. Each group had 5 teeth and 10 holes. There were the following combinations: easy one Z350, Ae, easy one AP-XN A F, easy one TPHU, B D, S3Z350, B, E, S3AP-X, B, B, S3AP-X, B, F, S3TPHU, C, D, XV, AP-X, C, E, AP-XO, C, E, AP-XO. Each hole is filled with adhesive and resin according to the description of binder and composite resin. The teeth were immersed in 1% methylene blue at room temperature for 24 h after 24 hours in 37 鈩，
