Which Factors Influence the Shear Bond Strength of Sealant Materials?

Purpose:
This study investigated the influence of several methodological details on the shear bond strength (SBS) testing of pit and fissure sealants. The following variables were considered: type of enamel surfaces, prismatic vs aprismatic enamel, etching time, and aging and shearing procedures.

Materials and Methods:
The surfaces of 180 healthy human third molars were divided into 4 different sections (mesial, distal, buccal, and oral). After tooth separation, the specimens were randomly allocated to the following groups: 1) enamel preparation: prismatic vs aprismatic; 2) etching: 30 s vs 60 s; 3) aging: 1 day or 3 months vs 5000 thermocycles; 4) shearing: notched-edge method (ISO 29022:2013) vs knife-edge method. After following each protocol, SBS was determined using a universal testing machine, followed by failure mode analysis. Data were analysed using Mann-Whitney U-tests and regression analyses.

Results:
In the aprismatic enamel group, the longer etching time resulted in slightly, not statistically significantly higher SBS. When aging sealants on aprismatic enamel with different procedures, significantly lower SBS was found for 5000 thermocycles. In the case of aprismatic enamel etched for 60 s and sheared with the notched-edge blade, there was no significant difference between the aging procedures. Failure mode analysis showed adhesive failures to be predominant. Simple linear regression revealed that all of the included factors significantly influenced SBS. In a multiple linear regression model, the variables “aprismatic enamel” and “distal surface” were associated with a higher SBS; “5000 thermocycles” reduced SBS significamtly.

Conclusion:
Enamel grinding, aging method, and type of enamel surface significantly influenced the SBS.

Keywords:

哪些因素影响密封材料的剪切结合强度？
目的：
本研究探讨了几种方法细节对窝沟封闭剂剪切强度（SBS）测试的影响。考虑以下变量：牙釉质表面型、棱柱VS aprismatic搪瓷，刻蚀时间，老化和剪切过程。
材料与方法：
将180例健康人第三磨牙的表面分为4部分（近中、远侧、颊侧和口腔）。拔牙后分离，标本随机分为以下几组：1）漆的制备：棱柱VS aprismatic；2）蚀刻：30比60；3）时效：1天或3个月与5000个热循环；4）剪切：缺口边缘的方法（ISO 29022:2013）VS刀口法。在每个协议之后，SBS使用通用测试机进行测试，然后进行故障模式分析。数据分析采用Mann-Whitney U检验和回归分析。
结果:
在aprismatic搪瓷组、更长的蚀刻时间导致轻微，无统计学显着较高的SBS。当老化密封胶在aprismatic搪瓷不同程序，降低SBS被发现的5000个热循环。在aprismatic搪瓷蚀刻60秒和剪切的切口边缘叶片的情况下，老化程序之间无显著性差异。失效模式分析表明胶粘剂失效占主导地位。简单线性回归分析表明，各因素对SBS影响显著。多元线性回归模型中，变量“aprismatic搪瓷”和“远中面”与更高的SBS相关；“5000个热循环，降低SBS significamtly”。
结论：
釉质的研磨、老化方法和釉质表面类型对SBS有显著的影响。

哪些因素影响密封材料的剪切粘结强度?

目的:
本研究考察了几种方法的影响，分析了坑和裂缝密封胶的剪切粘结强度(SBS)试验。考虑了以下的因素:牙釉质表面的类型、棱镜和杏牙釉质、蚀刻时间、老化和剪切过程。

材料与方法:
180个健康的人类第三臼齿的表面被分成4个不同的部分(mesial,distal,buccal和口服)。在牙齿分离后，这些标本被随机分配给以下的组:1)珐琅剂:prismatic和杏色;2)蚀刻:30 s vs 60 s;3)老化:1天或3个月vs 5000热循环;4)剪切:边缘法(ISO 29022:2013)vs刀锋法。在遵循每个协议之后，SBS使用一个通用的测试机器来确定，然后是失败模式分析。使用mann - whitney u - test和回归分析来分析数据。

结果:
在杏牙釉质组中，较长时间的蚀刻时间导致轻微的，没有统计学上明显较高的SBS。当用不同的方法处理杏牙釉质上的老化密封剂时，发现有5000个热循环的SBS明显较低。在杏牙釉质浸蚀60 s的情况下，用锯齿刃剪断，老化过程没有明显的区别。失效模式分析表明，胶粘剂失败占主导地位。简单线性回归揭示了所有包含的因素对SBS产生了显著的影响。在多元线性回归模型中，变量“杏牙釉质”和“远端表面”与较高的SBS相关联;“5000热循环”显著减少了SBS。

结论:
牙釉质磨削、老化方法和釉面类型对SBS有重要影响。

材料和方法：
将180只健康人体第三磨牙的表面分为4个不同部分（近端，远端，颊部和口部）。牙齿分离后，将样品随机分配到以下组：1）釉质制剂：棱柱体与无棱镜; 2）蚀刻：30秒vs 60秒; 3）老化：1天或3个月vs 5000个热循环; 4）剪切：切边法（ISO 29022：2013）与刀刃法。在遵循每个协议之后，使用通用测试机确定SBS，然后进行故障模式分析。使用Mann-Whitney U检验和回归分析分析数据。
