【摘要】:目的比較3種市售的一步法自酸蝕粘接劑的吸水性及溶解性,為臨床操作提供指導(dǎo)。方法選擇3種一步法自酸蝕粘接劑Adper Easy Bond(AEO)、Optibond All-in-one(OP)和Beauti Bond(BB),各制備50個(gè)圓盤試件(直徑為8.0mm,厚度為1.0mm),浸泡于去離子水中,并分組于不同浸泡時(shí)間段(1天、7天、30天、90天、180天),通過浸水前后質(zhì)量變化測定其吸水值與溶解值。結(jié)果在每個(gè)浸泡期,OP的吸水值、溶解值均為最高,AEO吸水值居中、溶解值最低,BB吸水值最低而溶解值居中,不同品牌粘接劑組間比較,差異均有統(tǒng)計(jì)學(xué)意義(P0.05);3種粘接劑的溶解值均隨時(shí)間延長顯著增加,不同浸泡時(shí)間組內(nèi)比較,差異均有統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論 3種市售的一步法自酸蝕粘接劑固化后的吸水性和溶解性明顯不同,可能與其組成有關(guān)。
[Abstract]:Objective to compare the water absorption and solubility of 3 kinds of commercially available one-step self etch adhesives, to provide guidance for the clinical operation. Methods 3 kinds of one-step self etching adhesive Adper Easy Bond (AEO), Optibond All-in-one (OP) and Beauti Bond (BB), the preparation of the specimen (50 the diameter is 8.0mm, thickness 1.0mm), soaked in distilled water, and grouped in different soaking time period (1 days, 7 days, 30 days, 90 days, 180 days), by changing the mass before and after immersion determine the water absorption value and solubility value. Results in each soaking period, the water absorption of OP value, solution the values were the highest, AEO absorption value is intermediate, dissolution was the lowest, BB absorption value is the lowest and the solution center, compare different brands of adhesive between groups, the differences were statistically significant (P0.05); 3 kinds of adhesive were dissolved with time increased significantly, compared with different soaking time in the group, there were statistically significant differences (P0.05 conclusion). The water absorbability and solubility of the one step method for the 3 marketed self etching adhesives are obviously different, which may be related to their composition.

【正文快照】: 一步法自酸蝕粘接劑由于其臨床操作簡便,技術(shù)敏感性較低,因此在臨床上的應(yīng)用日益廣泛,然而,對于粘接的耐久性問題卻受到一定的質(zhì)疑。其中水吸收被認(rèn)為是導(dǎo)致粘接界面降解的主要因素之一[1-2]。與傳統(tǒng)的多步驟酸蝕-沖洗類粘接系統(tǒng)相比,一步法自酸蝕粘接劑因含有酸性單體、親水,
