Other water channels were seen ‘reflecting’ downwards from the junction between the adhesive and the resin composite (Fig. Table 3 summarizes the studies which compared the bond strengths between sound dentin and CAD achieved with various adhesive systems. Excessive drying leads to collagen collapse, which will impede penetration of the bonding agent [48]. Ziel bei allen vorgestellten Techniken ist es, möglichst viel Zahnhartsubstanz zu erhalten, auf unnötige endodontische Behandlungen und Stiftinsertionen zu verzichten und somit eine möglichst lange Lebensdauer des Zahnes zu ermöglichen.

Bonding to enamel is still today best accomplished using this etch&rinse approach. Figure 12.1. About Dental Adhesives Created with your patients in mind, 3M dental adhesive options maintain the durability and esthetics of dental restorations while minimizing post-op sensitivity. Admira Fusion . Those systems with slightly higher pH, ie, mild or ultra-mild adhesives, interact with the dentine surface in two ways. Denn die unterschiedlichen Produkte auf dem Markt müssen stets gemäß Packungsanweisung verwendet werden. Der Zahn, aber auch das Zahnfragment, wird entsprechend den Vorgaben des Adhäsivsystems behandelt. As the market leader in dental adhesives, 3M offers superior bond strength, ease of use and versatility for a variety of direct and indirect dental bonding, restoration and sealing applications. auch vorgewärmtes oder schallaktiviertes Komposit) zusammen ausgehärtet. Damit die adhäsive Restauration funktioniert, ist die korrekte Anwendung des Haftvermittlers (Adhäsivs) entscheidend. Alle Themen; Anzeige ... (Etch&Rinse-Systeme). Ich kann diesen Service in jedem Newsletter abbestellen. (C, composite; H, hybrid layer; D, dentine.). These adhesives contain acidic primers, which can be ionized in the presence of water to form hydronium ions (H3O +) [47]; hence, the use of dentine conditioners is not required. Optragate) oder spezielle Wattepads (z.B. Bei der Haftung auf Dentin sind heute die Self-Etching-Systeme gut. Es ist entscheidend, dass die Glasfasern industriell mit der Kompositmatrix benetzt werden, da ansonsten eine Abplatzung des Verblendkomposits riskiert wird. The change with time to a less acidic pH may make t… Manikandan Ekambaram, ... Jukka Pekka Matinlinna, in International Journal of Adhesion and Adhesives, 2015. The resin monomers infiltrate into the dentin tubules to form resin tags. The fact that fluid transudation rapidly occurs across polymerized dentine adhesives implies that there are interconnected porosities or channels within the adhesives. The aim of this study was to investigate the effect of dentin dehydration and composite resin polymerization mode on bond strength of two SEAs. (all-in-one single-step systems) [31,32]. Indeed, it is generally accepted that if an adhesive system has a very low pH [pH <1], its acid reaction with HAP is excessively aggressive, leaving the dentine almost completely demineralised [40,44]. The mechanical bond of the adhesive to the collagen network and to some extent to the inside of the dentin tubules is what makes it possible for the composite resin to mechanically attach itself to the dentin. The hydrophilic group has an affinity for the dentin surface, and the hydrophobic group has an affinity for the resin. Das Fragment muss für das Reattachement rehydriert sein. Confocal images in reflection and fluorescence mode were performed as described by Sauro et al., [174,177], using sodium fluorescein to stain the exposed collagen. Wichtig ist auch hier, dass die Trockenlegung während der Befestigung gewährleistet ist. Dentinal fluid transudation across simplified dentine adhesives has been shown to occur when they were bonded to non-carious, deep, vital human dentine (Chersoni et al., 2004; Tay et al., 2004a), and even from dowel spaces created in vivo in endodontically treated teeth, which, presumably, contain water within the dentinal tubules (Chersoni et al., 2005). FTIR analysis and confocal (CLSM) z-stack single projections and topographical reconstructions. The idea of adhesive bonding to dentin was postulated more than 50 years ago as involving a potential chemical bond between the methacrylate group of resins to the collagen surface of dentin. NeuHenry Schein Dental spendet 1.000 Euro an Asphalt e.V. Apart from water trees, spherical water droplets could also be identified in HEMA-free, one-step self-etch adhesives (Fig. Therefore, incompatibility with self-etch adhesives (SEAs) should be taken into account with their use. 5.6). Dabei ist zu berücksichtigen, dass die Verarbeitung der Fasermaterialien (z.B. 4a und b). The thickness of the HL and the length of resin tags depend on the aggressiveness of the etching agent or the acidic monomer (Eliades et al., 2005; McCabe and Walls, 2008; Nakabayashi and Pashley, 1998). Severe water-treeing in an adhesive, occupying more than half the volume of the adhesive layer (A). So far, in vitro and in vivo research has indicated that etch&rinse adhesives can achieve high-quality adhesion to both enamel and dentine (Fig. 4.2. Bei selbstadhäsiven Befestigungsmaterial kann auf eine Dentinvorbehandlung verzichtet werden. This reaction leads to good long-term stability of the adhesive bond, which has been demonstrated in both in vitro [68,69] and clinical studies [70–72]. Scotchbond Multi-Purpose (3-step E & R), BS of tested adhesives were significantly higher to SD than CAD after etching with H3PO4, Use of MMPs inhibitors prior to application of tested adhesive did not affect BS to CAD, BS (after 1 week) of tested adhesives was significantly higher to SD than CAD, BS of Single Bond 2 to SD and CAD were reduced significantly in both control and 2% CHX pretreatment groups after 6 months of storage, BS of Clearfil SE Bond was significantly higher to SD than CAD, Pretreatment with 0.95 mM HOCl improved BS of Clearfil SE Bond to CAD, Adper Single Bond Plus (2-step E & R), BS of tested adhesives was significantly higher to SD than CAD, Application of grape seed extract and glutaraldehyde significantly improved BS to both SD and CAD, All Bond 2 and Clearfil Liner Bond 2 produced significantly lower BS to CAD than SD, No significant difference in BS between SD and CAD for Scotchbond Multi-Purpose, Scotchbond Multi-Purpose Plus (3-step E & R) primer+Adhesive, Experimental primer (50% HEMA in water)+Scotchbond Multi-Purpose Plus adhesive, Clearfil Liner Bond 2 and Clearfil Liner Bond 2V produced significantly lower BS to CAD than SD. Die minimalinvasive Füllungstechnik wurde erst dank der adhäsiven Befestigung auf der Zahnoberfläche möglich. D. PASHLEY, F. TAY, in Dental Biomaterials, 2008. Scanning electron micrograph of epoxy resin replica of water droplets on the surface of a simplified one-step self-etch adhesive bonded to vital human dentine. Das Fragment ist in der Regel einfacher zu positionieren, wenn die Kanten nicht präpariert oder abgerundet werden. 8.9). 6a und b). Sie können Ihre Auswahl jederzeit unter "Cookie-Einstellungen“ am Seitenende ändern. „Kratztests“ oder ähnliche Methoden sind diesbezüglich nicht zuverlässig! One component nano-reinforced self-etch bond in a bottle delivery system. [31] showed no significant difference in the bond strength of the 2-step self-etch adhesive to CAD following the four caries removal methods (abrasive paper, slow-speed bur, laser and Cariosolv). Since the incorporation of hydrophilic monomer blends in simplified adhesives (two-step etch-and-rinse and one-step self-etch adhesives) dramatically reduced bond longevity, the need of a hydrophobic coating with a not-solvated bonding layer seems to be pivotal to reduce water sorption and stabilize the hybrid layer over time, i.e., etch-and-rinse three steps and self-etch two-step adhesives should be preferred to simplified ones. However, tensile bond strengths of adhesive resins to ground enamel were similar for self-etching primers and phosphoric acid groups [80]. Because of the decreased dimension of the particles in the nanofillers, a wide size distribution and increased filler load is achieved, which decreases polymerization shrinkage [4], and increases mechanical strength and resistance to fracture. Sonoda et al. A hydrophobic self-etch dental adhesive composition including a hydrophobic, surfactant-type acidic monomer. The main factor influencing the pulpal reaction under restorative materials is the presence of bacteria on the cavity walls followed by the remaining dentin thickness [85]. darin, dass es zu weniger postoperativen Hypersensibilitäten kommt. Admira Fusion x-tra. 5.11). 3. Viviapad) zu lagern, bevor es gebraucht wird (Gefahr der Evaporation von Lösungsmitteln und all fälliger Phasenseparation des Adhäsivs). bei Zirkondioxidkeramik nicht einfach zu erzielen. Then a bonding agent consisting of an unfilled resin that consists of a hydrophobic monomer such as bisphenyl-A-glycidyl methacrylate (Bis-GMA), triethyleneglycol dimethacrylate (TEGDMA), and urethane dimethacrylate and hydrophilic monomers such as HEMA is applied [19]. "Etch & Rinse 2-step": iBOND ® Total Etch is the light-curing Etch & Rinse (2-step) bonding system. A very thin layer (<2 µm) of demineralised fluorescein-stained dentine collagen could be detected during fluorescence confocal imaging. Weitere Informationen zum Thema Datenschutz. In their mildest forms, they appeared as isolated fractal-like, branched structures that extended from the surface of the bonded dentine into the adhesive layer (Fig. Tachibana et al. On the other, the extent of dentin dehydration has a great role in the quality of adhesion of these resin materials to dentin. Good examples are Ultra-Etch from Ultradent, 3M ESPE Etchant Gel, and Select HV Etch from Bisco. Because of the presence of the smear layer, and also because of smear plugs blocking the dentinal tubules, self-etch adhesives have been claimed to provoke less post-operative sensitivity in patients than the etch-and-rinse approach [61,62]. Conversely, in 1-step self-etch adhesives, the different components are provided in one bottle; hence, they are referred to as “all-in-one” adhesives [52]. AC Applicator type 2. Increased friction between orthodontic wires and bracket surfaces has been attributed to micro/nanoasperities or mechanical interlocking at the micro- or nanolevels [7] (Figure 12.2). This generation used the total-etch technique, ie, etching enamel and dentin [69] to completely remove the smear layer over the dentin tubules [61]. There are two theories for the major shrinkage of the demineralized dentin matrix when it is air-dried. Wenn man ein Zahnfragment erneut am Zahn befestigen will, kommen adhäsive Techniken zur Anwendung, wie sie beim Befestigen von Veneerschalen angewendet werden (in der Regel reichen rein lichthärtende Kompositmaterialien). These three-step total-etch adhesives had hydrophilic low-viscosity resin monomers that were applied as primers after the dentin was etched. C: SEM micrographs taken from a dentine specimen treated with 10-MDP and subsequently rinsed with water/ethanol challenge. Note the presence of residual smear plugs inside the tubules below the dentine surface (Pointers). Aber Achtung: Wenn zusätzlich Dentin exponiert ist, muss darauf geachtet werden, dass bei den selbstätzenden Systemen keine Phosphorsäure auf das Dentin gelangt, da sonst die Haftkraft deutlich abnimmt. Xu, in Material-Tissue Interfacial Phenomena, 2017. OptiBond® All-In-One simplifies the restorative procedure by providing superior adhesion to all surfaces and substrates for both direct and indirect applications - even indirect metal-based restorations when used with NX3 resin cement. 5). One more important research outcome to highlight is that 10-MDP may inhibit secondary caries [45]. In the late 1980s, the third generation of bonding resins was introduced, which either modified or removed the smear layer to allow resin penetration in the subjacent dentin [26,67,68]. Figure 8.9. Gerade bei umfassenden Formveränderungen von Zähnen (z.B. CLEARFIL SE BOND 2 does it. This reaction necessitates the displacement of the phosphate groups in the hydroxyapatite mineral phase by the acid functional group of the bonding agent [65]. HEMA is miscible with water in all proportions and is often utilized as a transitional, polymerizable solvent for other ionic resin monomers that are sparingly soluble in water. Clearfil Protect Bond, Bioactive dental adhesive: Two component self-etch adhesive: Primer: MDP, MDPB, HEMA,Hydrophilic dimethacrylate, Water: Kuraray Medical Inc., Okuyama, Japan: Bond: MDP, Bis-GMA, HEMA,Hydrophobic dimethacrylate,dl-Camphorquinone,N,N-Diethanol-p-toluidine,Silanated colloidal silica, Surface treated sodium fluoride This lowers the dentin permeability and diminishes the sensitivity to fluid from the pulp chamber [78]. Application tips type 45. The degree of interaction with the tooth surface varies with acidity of the self-etch formulation. These penetrate the tooth surface to only a slight extent, typically in the nano-metre range [59]. F. Li, ... H.H.K. Also, many recent studies [56–59] are in total agreement with the conclusions of Tay et al. Occasionally, through-and-through channels that were oriented perpendicular to the hybrid layers could also be observed spanning the entire thickness of the adhesive layer (Tay and Pashley, 2003a; Ito et al., 2005a). The introduction of nanofiller components originally was introduced to enhance some physical properties of the hardened restorative composites. Thus the amount of dentin demineralized by acid conditioning as well as the impregnation of resin into the intertubular dentin (forming the hybrid layer) is probably related to the degree of closure and direction of the dentinal tubules [77]. Wet bonding was introduced, which requires a subjective analysis by the clinician; the clinician must determine if the dentin is too wet or too dry. Background: Self-etching adhesives are believed to prevent postoperative sensitivity when used under posterior resin-based composite restorations. 1. [43, 54] and Chaves et al. Descriptive statistics of the included studies. Being part of a large molecule (e.g. Orthodontic treatment may involve removal of some teeth to alleviate dental crowding or to treat some types of malocclusions. Ihr Vorteil liegt v.a. A phosphoric acid etching system may open the tubules and allow more dentinal fluid to wet the dentin surface [78]. Imagine using your two-step self-etch adhesive for core build-ups and even indirect restorations next to direct restorations. However, the exact measurements of these micro/nanoasperities have only been evaluated using AFM. Introduction There are many dental adhesives available on the market. Dazu muss das Teilstück einprobiert werden. A 35% phosphoric acid etch&rinse phase removes the enamel top layer for a few micrometers, and selectively dissolves hydroxyapatite crystals within prismatic and interprismatic enamel.22 This increases microscopic roughness, surface area and surface energy. Bei Adhäsivsystemen und Kompositzementen, welche im Kühlschrank gelagert werden, ist es von Vorteil, diese möglichst rasch ins Behandlungszimmer zu nehmen, da die Konversionsrate (Polymerisationsgrad) bei Raumtemperatur höher ist. Total-etch treatment with 37% phosphoric acid exposing deeper etching of the enamel. After partial removal of the mineral phase from the dentin substrate using an etching agent or an acidic monomer, the adhesive monomers penetrate into the spaces in the demineralized dentin substrate and form a zone after polymerization of the adhesive. Es empfiehlt sich, davon abzusehen, das Adhäsiv über Minuten in einem lichtgeschützten Behälter (z.B. Easy and fast application – one-coat, one-cure technique . The bonding mechanism of the fourth-generation adhesive systems is a three-step total-etch process: (1) condition, (2) prime, and (3) bond. im ästhetischen Bereich: Schmelz immer ätzen, auch bei Haftvermittlern, bei welchen auf die Schmelzätzung verzichtet werden kann. „Self-etch“-Systeme besitzen saure Monomere. Among the studies that have evaluated the bond strength using 2-step etch-and-rinse adhesives, 13 studies showed significantly higher and 2 studies [23,40] showed no difference in the bond strength between sound dentin compared to CAD. Admira Protect. Vorsicht ist einzig nach wie vor bei den Einflaschensystemen gegeben. 3) demonstrated that the mildly acidic resin-bonding promoted by 10-MDP produces more effective and stable bonds to HAP, Further studies [32,40] suggest that 10-MDP produces more effective and stable ionic bonds to HAP compared to those other types of functional monomers (i.e. Einmaliges Auftragen: iBOND Self Etch wird in nur einer Schicht einfach, schnell und sicher appliziert. Zudem können relativ steife Matrizen gut in den Sulcus gelegt werden, um die PBE durchzuführen. 4.3. Im Falle der Kompositfüllung ist die Gestaltung des Kontaktpunktes vereinfacht, da der Keil dank PBE nicht die Matrize eindrückt. However, an additional role of some functional monomers is to promote chemical bonding to the calcium of the HAP present in dental substrates [42,42]. No shaking, no rubbing. The self-etch adhesives can be classified into two subtypes: two-step self-etch adhesives (acidic primer + bonding) and one-step self-etch adhesives (all in one). Oftmals kam es zur einseitigen Dezementierung und das Metallgerüst schimmerte gerne durch die Pfeilerzähne hindurch. AC Activator. Our iBOND adhesives are a trusty team, delivering exactly what you need for perfect bonding: reliable adhesion, whatever the indication and technique "All-in-one" iBOND ® Self Etch – The light-curing, self-etching, All-in-One adhesive. Bei einem Adhäsivsystem mit hohem Fülleranteil wird auf die Lichtpolymerisation vor der Befestigung des Fragmentes verzichtet und das Adhäsiv wird dann zu sammen mit dem Zement oder Flowable (evtl. The progress through each stage of the review is shown in Fig. A: Confocal image showing the presence of residual smear layer both on the dentine surface and inside the dentinal tubules. Im Sinne von kostengünstigen Alternativen oder langzeitprovisorischen Lösungen können heute mittels direkter Kompositklebebrücken Patienten neue Behandlungsmethoden angeboten werden (Abb. Keywords: dental bonding system; adhesion; self-etch adhesive; universal adhesive; bond strength; dentin; scanning electron microscopy; adhesive layer 1. It was found that a minimum of a 300 mW/cm2 output was sufficient to cure composite resin 2–3 mm thick when irradiated for 20–30 s [86]. Exemplary copolymerizable adhesion promoters include dipentaerythritol-pentaacrylate-phosphoric acid ester (PENTA); bis(2-ethylhexyl)hydrogen phosphate; 2 … Material application. Der Erfolg der adhäsiven Restauration ist maßgeblich abhängig von der richtigen Anwendung der Haftvermittler. In the search for fewer application steps and simplification, a two-step etch&rinse approach combines the priming and bonding steps into one; these adhesives are frequently referred to as ‘one-bottle adhesives’ and misleadingly suggest a single application step. 1. By continuing you agree to the use of cookies. [55] concluded that the thickness of the smear layer has no adverse effect on bonding of mild self-etch-adhesives (CMB, Clearfil Mega Bond, Kuraray Noritake Dental Inc., Tokyo, Japan) (pH 2) to dentine. For instance, the use of hydrophilic spacers of monomers in an adhesive system can increase water sorption and solubility, while the use of hydrophobic spacers can decrease these values [38,39]. Die Technik funktioniert in der Praxis durchaus – Grundvoraussetzung ist dabei, dass das erste Kompositinkrement unter suffizienter Trockenlegung erfolgt. Water droplets that traversed the adhesive layer are trapped by the hydrophobic composite above and appear as hemispherical voids along the composite-adhesive interface. 5.7). Futurabond U ist neben allen lichthärtenden Kompositen auch mit chemisch oder dualhärtenden Kompositen kompatibel, und das ohne Hinzumischen eines zusätzlichen Aktivators. Therefore, several mechanisms of adhesion including HL and chemical bond formation can operate simultaneously and synergistically in forming the bonds to dentin. When it comes to adhesive bonding systems, there only 2 families–the self-etch and the total-etch. This kind of severe fractal-like water-treeing was observed from thermomechanical stress of the adhesive interface created by the use of a single-bottle, one-step self-etch adhesive. Entrapment of water droplets that emerged from the adhesive surfaces during the slow polymerizing of chemical-cured resin composites (Carvalho et al., 2004) also accounts for the apparent incompatibility when these composites were coupled to acidic adhesives in the presence of non-amine-type ternary catalysts (Cheong et al., 2003; Suh et al., 2003). Amaris . bauen sie in die Hybridschicht ein. However, Tay et al. 4.5. This primer aids in displacing water, expanding or reexpanding the collagen network, and thus promoting the infiltration of the monomer into the submicrometer- or nanometer-sized spaces within the collagen fiber network [19]. Thus, the resulting hybrid layer, which no longer contains HAP crystals, is prone to degradation processes similar to those occurring when simplified ERA systems are employed [16,32]. TEM photomicrograph of the adhesive–enamel interface produced after an etch&rinse procedure (OptiBond Fl, Kerr). The unfilled resin penetrates into the primed dentin, copolymerizing with the primer to form an intermingled layer of collagen and resin; this collagen–resin structure is commonly called the “hybrid layer” [26]. 5.8. However, the use of such a classification based on adhesive generations is not universally accepted. Deshalb gilt v.a. Themen Themen. No deposits of silver (black dots) can be observed, suggesting that the interface is adequately sealed. The one-bottle or all-in-one adhesives involve application of 1–3 layers a single bottle adhesive that contains acidic-methacrylates, hydrophilic monomers such as HEMA and some cross-linking di-methacrylates such as UDMA, TEGDMA, etc. Wie bei allen anderen zahnmedizinischen Fachgebieten gilt aber auch hier: Es liegt in der Fertigkeit und Indikationsstellung des Zahnarztes, ob die adhäsive Restaurationstechnik funktioniert. Different forms of silver-filled, interconnecting channels have been reported within the adhesive layers of some commercial brands of two-step etch-and-rinse and one-step self-etch adhesives (Tay and Pashley, 2003b). The exposed collagen could be degraded by bacterial proteases, compromising the integrity of the dentin–adhesive bond and, ultimately, the restoration [81,83]. These fluid droplets could be seen when impressions of the adhesive-coated dentine were taken using a relatively hydrophobic polyvinylsiloxane material and subsequently replicated with epoxy resin (Fig. The elastic modulus of wet demineralized dentinal matrix may be about 7 MPa [74], which is more than 1000 times lower than that of mineralized dentin [48]. Eine gute Adhäsion ist v.a. The primer can consist of a hydrophilic monomer such as HEMA. Nevertheless, 48 articles did not meet the inclusion criteria of this review and were excluded. The search using the electronic databases with the specified key words retrieved a total of 242 articles. ERAs require complete removal of smear layer and complete demineralisation of superficial dentine by 32-40% phosphoric acid etching (Fig. Examples include: ExciTE F, OptiBond Solo Plus, Prime & Bond NT and iBond Total Etch. Scotchbond™ Universal Adhesive offers one simple adhesive application technique for both direct and indirect indications and bonds to all surfaces including enamel, dentine, glass ceramic, zirconia, noble and non-precious alloys, and composites – without additional primer. For this purpose, nanotechnology has been introduced to study different orthodontic wires and bracket slots to evaluate nanomechanical properties and topographic pattern of these materials in order to understand factors affecting friction between orthodontic wires and brackets. The formation of the hybrid layer produces increased adhesive bond strengths to dentin [71]. The fourth generation of bonding agents appeared in the early 1990s [26]. Ter-butanol is a solvent with a similar vapor pressure to ethanol, but with a better capability for chemical reaction with monomers. Another frequently used name for this category of adhesives is ‘total-etch’ adhesives; this is, however, less appropriate because self-, Recent advances in posterior resin composite restorations, Applications of Nanocomposite Materials in Dentistry, Mechanical stability of resin–dentine bonds, As marketed simplified etch-and-rinse and self-, Nanotechnology and Nanoparticles in Contemporary Dental Adhesives, Since the incorporation of hydrophilic monomer blends in simplified adhesives (two-step etch-and-rinse and one-step self-, Understanding the chemistry and improving the durability of dental resin–dentin bonded interface, Eliades et al., 2005; McCabe and Walls, 2008; Nakabayashi and Pashley, 1998, Materials for the Direct Restoration of Teeth, , and increases mechanical strength and resistance to fracture. This rapid water movement differs from the relatively slower diffusional processes across bulk resin. Dies kann mit speziellen blutstillenden Pasten erfolgen oder auch unter Verwendung des Lasers. Amaris Gingiva. Dies umfasst auch Ihre Einwilligung nach Art. Therefore, a selective etch- ing technique has been proposed to incorporate the advantages of the total-etch system on enamel with the self-etch system on dentin 80. Water has to be present to allow the acid to ionize and thus be capable of carrying out its etching function [56]. According to the ‘water flux’ theory of water-tree formation (Tay et al., 2005a, 2005b), water trees are morphologic manifestations of water movement from the underlying dentine substrate into a partially polymerized adhesive resin matrix, in which the polymer chains are not sufficiently cross-linked to resist their displacement by the bulk free water. Also, self-etch adhesives are classified according to the acidity into four types: ultra-mild (pH > 2.5), mild (pH 2–2.5), intermediate (pH 1–2), and strong (pH < 1). Kommt es zu einem etwaigen Misserfolg, kann die Restauration einfach repariert werden. As marketed simplified etch-and-rinse and self-etch adhesives lack non-solvented resin coatings (Brackett et al., 2005; Van Landuyt et al., 2006), they behave as permeable membranes (Tay et al., 2004c, 2004d) that permit rapid through-and-through water movement (Fig. Indeed, there is good evidence that mild self-etch systems give the best results, both in vitro and clinically, of all bonding agents, with one study demonstrating excellent clinical performance for one brand of material (Clearfil SE Bond, CSE, Kuraray, Japan) for up to 8 years with only minor leakage [62].
