Comparison of bond strength of universal adhesives using different etching modes: A systematic review and meta-analysis

This review aims to evaluate whether the etch-and-rinse or self-etch mode is the better protocol for dentin adhesion by universal adhesives. A total of 15 articles were included in the meta-analysis. Two reviewers performed a literature search up to October 2020 in four databases: PubMed, Web of Science, Embase, and the Cochrane Library. Without considering the difference in aging mode, the analysis of the immediate and long-term bond strength of dentin showed that there was no statistical significance between the etch-and-rinse and self-etch mode of universal adhesive, and the long-term bond strength decreased relative to the immediate. In vitro studies suggest that prior acid etching did not improve bond performance. Whether from the perspective of long-term bonding performance or simplifying operating procedures, the self-etch mode is preferred.

“…It can be deployed either with or without prior acid etching of the tooth substrate (Sofan et al, 2017). In the current work, phosphoric acid was used to etch the tooth substrate (dentin) before adhesive application, since the literature shows that it results in a higher bond strength between material and tooth (Cengiz & Ü nal, 2019). Futurabond U has a clinically favourable in vitro research papers performance record, comparable with other universal adhesive systems (Chen et al, 2015) and is thus excellent for clinical use, like many other similar products.…”

Bonding of resin composite fillings, for example following root-canal treatment, is a challenge because remaining gaps grow and lead to failure. Here, phase-contrast-enhanced micro-computed tomography (PCE-CT) is used to explore methods of non-destructive quantification of the problem, so that countermeasures can be devised. Five human central incisors with damaged crowns were root-filled followed by restoration with a dental post. Thereafter, the crowns were rebuilt with a resin composite that was bonded conventionally to the tooth with a dental adhesive system (Futurabond U). Each sample was imaged by PCE-CT in a synchrotron facility (ID19, European Synchrotron Radiation Facility) with a pixel size of 650 nm. The reconstructed datasets from each sample were segmented and analysed in a semi-automated manner using ImageJ. PCE-CT at sub-micrometre resolution provided images with an impressive increased contrast and detail when compared with laboratory micro-computed tomography. The interface between the dental adhesive and the tooth was often strongly disrupted by the presence of large debonded gaps (on average 34% ± 15% on all surfaces). The thickness of the gaps spanned 2 µm to 16 µm. There was a large variability in the distribution of gaps within the bonding area in each sample, with some regions around the canal exhibiting up to 100% discontinuity. Although only several micrometres thick, the extensive wide gaps may serve as gateways to biofilm leakage, leading to failure of the restorations. They can also act as stress-raising `cracks' that are likely to expand over time in response to cyclic mechanical loading as a consequence of mastication. The observations here show how PCE-CT can be used as a non-destructive quantitative tool for understanding and improving the performance of clinically used bonded dental restorations.

“…An important point is also the infl uence of the application aids [10,12,16,17] and the choice of the aging process [14,18], for example only storage in water for days or months as well as thermocycling [8,10,15,17]. The methods of determining the adhesion [5,15,25,26] may differ even all in choice of the debonding speed [18,19,25]. In the review by Scherrer [5] 147 studies with six different adhesives were summarized.…”

The aim of this randomized in vitro study is to clarify if there are differences between the dentin adhesives as well as their adhesion and fracture behaviour. The study design was based on the ISO standard TS 11405 (2003). For this purpose, ninety extracted, caries-free human molars were embedded in a plastic block, and the dentinal surfaces were dissected free. Teeth were divided into three groups (n = 30) and each treated with a different adhesive system (SYC: Syntac Classic; CSE: Clearfi l SE, CS3: Clearfi l S3). All trial teeth were coated with a cylindrical standardized test specimen (diameter: 3.0 mm, height: 3.0 mm) on buccal surfaces with an ISOconforming application aid. The aging of the samples was achieved by thermocycling (500 cycles). Thereafter, the adhesive forces (MPa) of the various dentin adhesive systems were determined by means of shear bond testing with a universal testing machine from Zwick. The samples were examined under a scanning electron microscope at 20x and 2000x magnifi cation for their fracture modes (adhesive, cohesive, mixed). Furthermore, parametric Weibull regression models were applied to evaluate whether there was a signifi cant association between shear bond strength and the used adhesive system. Weibull analysis was performed using R software (version 2.11.1, R Foundation for Statistical Computing, Vienna, Austria). Differences between groups were tested using Wald tests, and p-values below 0.05 were considered signifi cant. CSE (3.97 MPa), followed by SYC (3.02 MPa), and CS3 (2.16 MPa) had the highest bond strength averages. The result of the statistical evaluation shows statistical differences between the different groups. Mostly mixed fractures were observed. SYC (m = 6.35) was most reliably followed by CSE (m = 4.75). The lowest Weibull module scored CS3 (m = 3.91).Under the limitations of this study, it can be stated that the differences between the groups were signifi cant and the One-Step Self-Etch-system (CS3) showed the lowest values. Additionally one major problem was the acrylic application aid (split mould according to ISO/TS 11405), which may have transferred adverse forces to the specimen and which cannot be recommended for further studies.
