“…Another possible explanation for the strong bond strength of the EDTA-treated resin-dentin bond in this study is that a Single Bond which contains polyalkenoic acid was used as the adhesive. The carboxylic group of polyalkenoic acid and the hydroxyapatite on the dentin surface or incompletely dissolved hydroxyapatite in the exposed collagen fibrils could form an ionic bond, which may have contributed to strong resin-dentin bond interface 21) . Considering that the demineralization effect of EDTA depends on the concentration and application time, the application of 0.1M EDTA for 60 seconds appears to be suitable for use clinically in terms of the immediate high bond strength and durable bonding.…”

The effect of the ethylenediaminetetraacetic acid (EDTA) treatment on the hybrid layer durability of total-etch dentin adhesives was investigated. A flat dentin surface was exposed and treated with 37% phosphoric acid or 0.1M EDTA. Dentin adhesive was applied and a 4 mm thick composite resin was built-up. Twenty 0.9×0.9 mm 2 resin-dentin beams were fabricated in each experimental group. Artificial aging with 10% NaClO was performed in half of the experimental groups for 1 hour. A micro-tensile bond strength (µTBS) test was performed and the bonded interface was analyzed with transmission electron microscopy (TEM). The 37% phosphoric acid-treated group showed a lower µTBS after artificial aging, whereas the 0.1M EDTA-treated group did not. TEM analysis revealed collagen fibrils dissolved in the 37% phosphoric acid-treated group but not in the 0.1M EDTA-treated group. Undissolved minerals were observed in the 0.1M EDTA-treated group. In conclusion, a dentin treatment with 0.1M EDTA is effective in improving the hybrid layer durability.

“…Ion exchange takes place between the glass ionomer cement and the oral fluids as well as between the glass ionomer cement and the tooth tissue 6) , leading to formation of ionic bonds between the synthesized polyalkenoic acid and the surface calcium ions of exposed hydroxyapatite 7,8) . On this premise, the unique properties of selfadhesiveness between glass ionomer cements and human hard tissues such as bones and teeth can be attributed to the presence of ionic bonding 7,8) . In general, the water-mediated ion exchange in glass ionomer cements begins during initial hardening and continues thereafter at a slower rate.…”

The purpose of this study was to analyze the ions released from a surface pre-reacted glass ionomer (S-PRG) filler in distilled water or lactic acid solution. S-PRG filler was mixed with either solution at 1000:1, 100:1, 10:1, and 1:1 ratios by weight. By means of inductively coupled plasma atomic emission spectroscopy and a fluoride electrode, elements released from S-PRG filler were identified to be Al, B, Na, Si, Sr, and F. To investigate the effect of solution pH on ion release, the pH values of the solutions before mixing and after 24 hours' mixing with S-PRG were measured. After 24 hours' mixing, the pH values of solutions at all ratios became more neutral or weakly alkaline regardless of their initial pH levels before mixing. In conclusion, results showed that S-PRG filler released several types of ions, and that ion release was influenced by the mixing ratio of the solution rather than the initial pH of the solution.

“…More recently, selective enamel etching with phosphoric acid has been highly recommended to improve the performance of the mild self-etch adhesives Erickson et al, 2009;van Meerbeek et al, 2011). However, the use of selective enamel etching or phosphoric acid etching for GICs/RMGICs has not been adequately explored, probably because these materials can adhere to the tooth hard tissue surfaces by chemical mechanisms (Wilson and Kent, 1972;Yoshida et al, 2000;Fukuda et al, 2003).…”

Abstract:Objective: This study deals with the effect of phosphoric acid etching and conditioning on enamel micro-tensile bond strengths (μTBSs) of conventional and resin-modified glass ionomer cements (GICs/RMGICs). Methods: Forty-eight bovine incisors were prepared into rectangular blocks. Highly-polished labial enamel surfaces were either acid-etched, conditioned with liquids of cements, or not further treated (control). Subsequently, two matching pre-treated enamel surfaces were cemented together with one of four cements [two GICs: Fuji I (GC), Ketac Cem Easymix (3M ESPE); two RMGICs: Fuji Plus (GC), RelyX Luting (3M ESPE)] in preparation for μTBS tests. Pre-treated enamel surfaces and cement-enamel interfaces were analyzed by scanning electron microscopy (SEM). Results: Phosphoric acid etching significantly increased the enamel μTBS of GICs/RMGICs. Conditioning with the liquids of the cements produced significantly weaker or equivalent enamel μTBS compared to the control. Regardless of etching, RMGICs yielded stronger enamel μTBS than GICs. A visible hybrid layer was found at certain enamelcement interfaces of the etched enamels. Conclusions: Phosphoric acid etching significantly increased the enamel μTBSs of GICs/RMGICs. Phosphoric acid etching should be recommended to etch the enamel margins before the cementation of the prostheses such as inlays and onlays, using GICs/RMGICs to improve the bond strengths. RMGICs provided stronger enamel bond strength than GICs and conditioning did not increase enamel bond strength.
