“…Since SEAs have etching capabilities themselves, unlike 3-step ER system, the use of an etchant with milder acidity to PA might be adequate. Some in vitro studies demonstrated that an alternative etchant applied prior to a universal adhesive improved the enamel bonding performance (111)(112)(113)(114). Moreover, unlike PA, this etchant had no bad effect on the dentin bonding performance (115).…”

Optimal strategies for the application of an adhesive differ between enamel and dentin because of the differences in their composition. The development of adhesive systems has mainly focused on the bonding of dentin, rather than on the enamel, by etching with phosphoric acid (PA). Dental adhesive technologies continue to rapidly advance, and various adhesive systems have been developed since the study of Buonocore in 1955. He introduced the enamel acid-etch technique. Then, the etch-and-rinse (ER) system was developed, and subsequently, the self-etch (SE) system. Universal adhesives are a new generation of one-bottle SE adhesives that can be applied with either ER mode or SE mode, or a combined system involving selective enamel etching mode. Since the combination of PA etching and the SE system differs from conventional ER systems, the enamel bonding strategy should be carefully considered. This concise review of the literature on reliable enamel bonding strategies should prove helpful to clinicians to choose an appropriate adhesive system to achieve optimal clinical outcomes.

“…Wong et al 23) showed that although the organic acid etching agent had the weak enamel etching effects, this agent can modify enamel surface with less demineralization than the phosphoric acid etching agent, thus minimizing the unfavorable effects for bonding to tooth substrates. Yao et al 24) reported that there were no significant differences in a micro-tensile bond strength between the organic acid etching and the phosphoric acid etching agents. Therefore, the organic acid etching agent was used instead of the phosphoric acid etching agent in this study.…”

The purpose of this study was to determine whether a system using a resin coating material (PRG Barrier Coat) with anticariogenic ability can effectively bond orthodontic brackets to human teeth. Resin-modified glass-ionomer cement system (Fuji Ortho LC, group 1) and resin composite cement systems (BeautyOrtho Bond) combined with a self-etching primer (group 2), with the resin coating material (group 3), and with the resin coating material after an organic acid etching agent (group 4) were used for bracket bonding. The mean shear bond strength (SBS) was significantly higher in group 1 than in groups 2, 3 and 4. Groups 2 and 4 exhibited a significantly higher mean SBS than group 3. The resin composite cement system combined with the resin coating material after the organic acid etching agent can serve as an alternative for orthodontic bracket bonding.

“…The mid-coronal dentin surface was split into two equal parts by cutting a groove of 0.3-mm width and 2.5-mm depth using a slow-speed diamond saw (Micracut 151, Metkon, Bursa, Turkey). A standard bur-cut smear layer was produced, as detailed before 29 (the preparation steps are detailed in the Supporting Information). The tooth specimens were then sectioned parallel to the dentin surface to obtain two dentin disk halves with a 2-mm thickness.…”

Apart from producing high bond strength to tooth enamel and dentin, a dental adhesive with bio-therapeutic potential is clinically desirable, aiming to further improve tooth-restoration longevity. In this laboratory study, an experimental two-step universal adhesive, being referred to as Exp_2UA, applicable in both etch-and-rinse (E&R) and self-etch (SE) mode and combining a primer, containing 10-methacryloyloxydecyldihydrogen phosphate (10-MDP) as functional monomer with chemical binding potential to hydroxyapatite, with a bioglass-containing hydrophobic adhesive resin, was multifactorially investigated. In addition to primary property assessment, including measurement of bond strength, water sorption, solubility and polymerization efficiency, the resultant adhesivedentin interface was characterized by TEM, the filler composition analyzed by EDS and the adhesive's bioactive potential estimated by measuring long-term ion release and assessing its anti-enzymatic and anti-bacterial potential. Four representative commercial adhesives served as reference/controls. Application in both E&R and SE mode resulted in durable bonding performance to dentin, as evidenced by favorable 1-year aged bond-strength data and a tight interfacial ultra-structure that, as examined by TEM, remained ultra-morphologically unaltered upon 1-year water-storage aging. TEM revealed a 20-µm thick hydrophobic adhesive layer with a homogeneous bioglass filler distribution. Adequate polymerization conversion resulted in extremely low water sorption and solubility. In-situ zymography revealed reduced endogenous proteolytic activity, while Streptococcus mutans biofilm formation was inhibited. In conclusion, the three/two-step E&R/SE Exp_2UA combines high bonding potential and bond-degradation resistance with long-term ion release rendering the adhesive anti-enzymatic and anti-bacterial potential.
