To compare the application of silane in the bond strength of fiberglass posts in different thirds of the cemented root with a self-adhesive system in an study.
Freshly extracted teeth were collected, which had indication of extraction for periodontal or orthodontic reasons. The study evaluated = 42 specimens that were divided into two large groups: I (control, without silane) and II (with silane); the resistance to adhesion in the respective thirds of the root (cervical, middle, and apical) was also evaluated. The prefabricated fiberglass posts were cemented with and without silane according to the manufacturer's instructions and were cemented with a resin-based cementing agent. The adhesion strength test was evaluated by the universal testing machine.
According to the results of this experimental trial, the fiberglass posts that did not receive silane had the highest adhesion strength of 26.5 ± 10.6 MPa, while silane-cemented posts only had 21.7 ± 8.1 MPa. The statistical analysis was performed using the Kruskal-Wallis test and work with a level of significance of < 0.05.
The use of silane as part of the cementing protocol in fiberglass posts does not influence the adhesion strength between the surfaces of the posts and the resin cement because there were statistically significant differences between both adhesion protocols.
This study has a great impact because according to the results, clinical decisions can be made when cementing the fiberglass posts through the application of silane or not.
在一项研究中，比较硅烷在自粘系统中对不同牙根三分之一处粘结的玻璃纤维桩粘结强度的应用情况。
收集因牙周或正畸原因有拔除指征的新鲜拔除牙齿。该研究评估了42个样本，分为两大组：I组（对照组，不使用硅烷）和II组（使用硅烷）；还评估了牙根相应三分之一处（颈部、中部和根尖部）的粘结抗力。预制玻璃纤维桩按照制造商说明分别在有硅烷和无硅烷的情况下，用树脂基粘结剂进行粘结。通过万能试验机评估粘结强度测试。
根据该实验试验结果，未使用硅烷的玻璃纤维桩粘结强度最高，为26.5±10.6MPa，而使用硅烷粘结的桩仅为21.7±8.1MPa。采用Kruskal-Wallis检验进行统计分析，显著性水平为<0.05。
在玻璃纤维桩粘结方案中使用硅烷不会影响桩表面与树脂粘结剂之间的粘结强度，因为两种粘结方案之间存在统计学显著差异。
本研究具有重大影响，因为根据结果，在粘结玻璃纤维桩时是否应用硅烷可做出临床决策。
