Abstract

Background/purpose

The dental adhesive market is constantly evolving to meet the demands of dentists and patients, but new products and upgrades should be rigorously evaluated before being used in clinical practice. This study investigated the physicomechanical properties and dentin bonding efficacy of a newly upgraded universal adhesive compared to its predecessor.

Materials and methods

Twenty-four molars were divided into four groups (n = 6/group) based on adhesive (new vs. predecessor) and application mode [self-etch (SE) vs. etch-and-rinse (ER)] for evaluating their dentin microtensile bond strength (μTBS), failure pattern, and bonding interface. Additional thirty-six molars’ crowns were perpendicularly sectioned to obtain flat mid-coronal dentin discs. The opposing dentin surfaces of each disc received contrasting treatments (new/predecessor adhesive applied in SE/ER mode), resulting in six interventions. The bonded discs (n = 6/intervention) were used to assess the adhesives’ survival probability employing a double-sided μTBS test. The other physicomechanical properties examined were adhesives’ oxygen inhibition layer (OIL), viscosity, hardness, elastic modulus, degree of conversion (DC), and in-situ DC.

Results

Both adhesive versions showed similar μTBS (P > 0.05), failure pattern (P > 0.05), and survival probability (P > 0.008). ER mode promoted resin tag formation and exhibited a slender adhesive layer for both adhesives. The newer adhesive version showed a thinner adhesive layer in general with narrower OIL (P < 0.001), less viscosity (P < 0.001), higher hardness (P < 0.05), elastic modulus (P < 0.05), DC (P < 0.001), and in-situ DC (P < 0.001).

Conclusion

While the newly updated adhesive had superior physicomechanical properties with more fluidity, its dentin bonding efficacy and survival probability were comparable to its predecessor.

评估最近推出的通用粘合剂与其前身相比所取得的进步

背景/目的牙科粘合剂市场在不断发展以满足牙医和患者的需求，但新产品和升级产品在用于临床实践之前应进行严格的评估。材料和方法根据粘合剂（新产品与旧产品）和应用模式[自酸蚀（SE）与蚀洗（ER）]将二十四颗磨牙分为四组（n = 6/组），评估其牙本质微拉伸粘接强度（μTBS）、失效模式和粘接界面。对另外 36 颗磨牙的牙冠进行垂直切片，以获得平坦的中冠牙本质圆盘。每个牙盘的相对牙本质表面都接受了对比处理（以 SE/ER 模式使用新的/前代粘接剂），共进行了六次干预。粘接后的牙盘（n = 6/干预）通过双面 μTBS 测试来评估粘合剂的存活概率。其他物理机械性能包括粘合剂的阻氧层（OIL）、粘度、硬度、弹性模量、转换度（DC）和原位 DC。结果两种粘合剂的μTBS（P >0.05）、失效模式（P >0.05）和存活概率（P >0.008）相似。ER模式促进了树脂标签的形成，两种粘合剂的粘合层都很薄。新版粘合剂的粘合层总体较薄，OIL 较窄（P <；0.001），粘度较低（P <；0.001），硬度较高（P <；0.05），弹性模量较小（P <；0.05），DC 较小（P <；0.结论虽然新更新的粘合剂具有更优越的物理机械性能和更高的流动性，但其牙本质粘接效果和存活概率与其前代产品相当。

期刊介绍： he Journal of Dental Sciences (JDS), published quarterly, is the official and open access publication of the Association for Dental Sciences of the Republic of China (ADS-ROC). The precedent journal of the JDS is the Chinese Dental Journal (CDJ) which had already been covered by MEDLINE in 1988. As the CDJ continued to prove its importance in the region, the ADS-ROC decided to move to the international community by publishing an English journal. Hence, the birth of the JDS in 2006. The JDS is indexed in the SCI Expanded since 2008. It is also indexed in Scopus, and EMCare, ScienceDirect, SIIC Data Bases. The topics covered by the JDS include all fields of basic and clinical dentistry. Some manuscripts focusing on the study of certain endemic diseases such as dental caries and periodontal diseases in particular regions of any country as well as oral pre-cancers, oral cancers, and oral submucous fibrosis related to betel nut chewing habit are also considered for publication. Besides, the JDS also publishes articles about the efficacy of a new treatment modality on oral verrucous hyperplasia or early oral squamous cell carcinoma.
