摘要
背景:本研究的目的是评估Scotchbond MP和Clearfil SE胶粘剂系统对玻璃纤维桩与根管间推出试验中粘结强度的影响。材料和方法:这项体外研究涉及在12个月内拔出的20颗人类犬牙。为了纳入样品,考虑了顶端完全形成且曲率小于45°的上犬齿。含有钙化根管的牙齿,影像学上可见的双弯曲或以前接受过根管治疗的牙齿被排除在样本之外。选择后,使用超声插入进行表面预防,然后用Gracey刮匙平滑。根管治疗由校准的操作人员按照预先建立的协议进行。接下来,准备根管开始接收Whitepost DC 2号玻璃纤维桩,移除2/3的空间。接下来,柱子被准备好粘合,用70%的酒精清洗,用37%的磷酸处理,然后接受两层硅烷。从那时起,根据胶粘剂系统将元件随机分为两组,使用RelyX ARC水泥:SCB组:Scotchbond MP, CFL组:Clearfil SE。将纤维桩胶结后,准备试件在万能试验机(EMIC)上进行推出试验进行力学试验。采用Tukey检验进行多重比较。采用显著性水平5%进行统计学计算。结果:双因素方差分析表明,所研究的因素之间没有统计学上显著的相互作用,但使用SCB集团胶粘剂系统产生更高的RU值。结论:使用ScotchBond粘接剂后,树脂胶合剂与牙根本质的结合强度更大,不同牙根部位的RU无差异。关键词:玻璃纤维桩;粘结系统;抗拉强度;
Adhesive strength in cementing fiberglass posts using different adhesive systems.
Background: The objective of this work was to evaluate the influence of the Scotchbond MP and Clearfil SE adhesive systems on the bond strength in the push out test between the fiberglass post and the root canal.
Material and methods: This in vitro study involved 20 human canine teeth extracted over a 12-month period. For inclusion in the sample, upper canine teeth with fully formed apices and curvatures less than 45° were considered. Teeth containing a calcified canal, with radiographically visible double curvature or that had undergone previous endodontic treatment were excluded from the sample. After selection, surface prophylaxis was performed using an ultrasound insert, followed by smoothing with a Gracey curette. Endodontic treatments were performed by a calibrated operator, following a pre-established protocol. Next, preparation of the root canal began to receive the Whitepost DC number 2 fiberglass post by removing 2/3 of this space. Next, the posts were prepared to be cemented, they were cleaned with 70% alcohol and conditioned with 37% phosphoric acid before receiving two layers of silane. From that moment on, the elements were randomly divided into two groups, according to the adhesive system, with RelyX ARC cement being used: Group SCB: Scotchbond MP and Group CFL: Clearfil SE. After cementing the fiber posts, the test specimens were prepared for mechanical testing using the push out test on the Universal Testing Machine (EMIC). Multiple comparisons were performed using the Tukey test. Statistical calculations were conducted adopting a significance level of 5%.
Results: The two-factor analysis of variance demonstrated that there was no statistically significant interaction between the factors studied, however the use of the SCB Group adhesive system produced higher RU values.
Conclusions: It was concluded that greater bond strength was obtained between resin cement and root dentin when ScotchBond adhesive was used and there were no differences in RU in the different root portions. Key words:Fiberglass posts, Adhesive systems, Tensile strength, Cementation, Dental prosthesis.
