Abstract (sommario):

Degradation starts at the resin-dentine bonded interfaces within a few months’ of bonding. There are two major causes of degradation of the bonded interfaces over time. The simplified dental adhesives that are routinely used in the contemporary clinical dental practice are extremely hydrophilic and are prone to water sorption, leading to hydrolytic degradation. Dentine matrix-bound metalloproteinases (MMPs) and cysteine cathepsins (CCs) are proteolytic enzymes that have been shown to degrade the uninfiltrated demineralized collagen at the bottom of the hybrid layer. Ethanol-wet bonding (EWB) with hydrophobic adhesive has been proven to improve the longevity of resin-dentine bonds in vitro. Chlorhexidine (CHX) treatment of demineralized dentine before bonding with adhesive resin has been shown to preserve resin-dentine bond durability in vivo and in vitro by inhibition of dentine matrixbound MMPs and CCs. However, it is not known whether simultaneous application of CHX and EWB would have any interactional effect on stability of resin-dentine bonds. 1-Ethyl-3-[3-dimethylaminopropyl] carbodiimide hydrochloride (EDC), both a dentine collagen cross-linker and a MMP inhibitor, has been shown to preserve dentine bond durability in vitro. However, both EDC and CHX are prepared in aqueous solutions using water as a solvent for application. The MMPs are hydrolases and the presence of residual water in the demineralized dentine following EDC and CHX applications will enhance dentine bond degradation. The general aims of this thesis were to investigate the effects of solvents in resindentine bonding, in particular the role of solvents in the enhancement of resin-dentine bond durability. In the earlier part of this thesis, the adjunctive application of 2% CHX with EWB using the simplified dehydration protocol for 60 s was examined as a bonding strategy to preserve dentine bond durability to sound and caries-affected dentine. The adjunctive application of EWB and CHX preserved bond durability of hydrophobic adhesive to both sound and caries-affected dentine after 12 months’ ageing. The same bonding strategy was applied to preserve the bond durability of luting fibre post to radicular dentine. However, the addition of 2% CHX to EWB did not further improve bond durability of hydrophobic adhesive to radicular dentine, when compared to EWB alone. In the later part of this thesis, the role of the solvents (commonly used in commercial dentine adhesives) in the enhancement of dentine bond preservation potential by CHX and EDC were assessed. The incorporation of 2% CHX in ethanol showed greater inhibitory effect on matrix-bound proteases than 2% CHX in water. Conversely, the use of acetone as a solvent for EDC also enhanced its dentine collagen cross-linking potential. The dentine collagen cross-linked by EDC in acetone was more resistant to enzymatic degradation. Within the limitations of this thesis, it could be concluded that solvents play a significant role in the enhancement of dentine bond durability. In general, ethanol and acetone are better than water for the preservation of dentine bond durability.

Abstract (sommario):

Introduction: Adhesion has become an important concept in modern restorative dentistry. It offers the ability to bond materials to the tooth without invasive tooth preparation. Numerous in-vitro strength tests have been used to determine the bond strength of adhesive systems. However, because the occlusal forces applied to. a restoration are complex, and made up of a combination of forces, no one test can satisfactorily predict the in-vivo behavior of an adhesive system. The majority of bond strength studies have used monotonic tests to assess the bond strength of materials and between the materials and the tooth. These tests are expedient, but do not simulate the cyclic forces that operate in the mouth. Tests that characterize this type of . stress are called fatigue tests. Fatigue can result in wear and fracture of materials or bonds. .Objectives: To investigate fatigue behavior of modern resin composites and resinbonded joints of both metal to enamel and ceramic to enamel. The main approaches to fatigue assessment, 'Fatigue Limit' and 'Fatigue Life'were compared Materials and Methods: Surface effects of fatigue One hundred and eighty samples of two historical composites1-2 and seven modern composites3 - 9 were subjected to 2000 stress cycles between 0 and 120N or 0 and 400N. Surface damage was measured as the diameter of the fatigue scar and subsurface damage was determined by silver nitrate staining. The hardness of both the surface and subsurface was also determined. Fracture Composite to composite Two hundred and twenty composite disks were fabricated using three materials.7 Ã‚Â• 9 After one day, one week, four weeks, and twelve weeks, fifty-five specimens of each material were removed from' water and divided into three groups of fifteen and one group of ten. Each group of samples was treated with one of three bonding systems10- 12 before adding a sec~nd increment. For each material, ten samples were subjected to Shear test in a Universal Testing Machine13 (CHS= 50 mmlmin). The fatigue limit test using fifteen samples per group were used to determine the fatigue limit using the staircase method (Draughn 1979). Metal or Ceramic to Enamel (via resin) Three hundred and forty-two discs of Ni/Cr-alloy14 were cast and treated by either sandblasting with aluminium oxide, or by sandblasting followed by electrolytic-etching in HCI. The disks were bonded to etched enamel with one of three dental bonding systems.1S - 17 One hundred and seventy-one ceramic disks were fabricated by sintering ceramic powder.18 One surface of each disk was etched with porcelain etching-gel19 for fifteen minutes and sandblasted with 50 J.Im A120 3. The prepared disks were then divided into three groups and were bonded to etched enamel using one of three dental bonding systems.1S - 17 Ten specimens of each group were sUbjected to a shear bond test (CHS 50 mm/min) and seventeen specimens of each group to a staircase fatigue test to determine the fatigue limit of the bonds. The remaining specimens from each group were placed in the custom made fatigue testing machine and allowed to cycle to failure between 0-20 kg, 0-10 kg or 0-5 kg (n=10 per load). The number of cycles at failure was analysed by Weibull statistics to determine the fatigue life Results: The surface studies in composites indicated that both surface and subsurface damage increased with increasing load. In general, small-particle composites experienced less damage than the large particle materials. At 12 kg, the surface damage was inversely proportional to the surface hardness, whereas at 40 kg, it was proportional to the subsurface hardness. At both loads, subsurface damage was directly proportion to subsurface hardness. For the composite to composite bonds, the fatigue limit values were approximately 30% of the shear bond strength values and the values were significantly different (p<0.01) for all nine groups. For metal to enamel bonds, the fatigue limit (after 5000 cycles) varied between 10.7 and 16.8 MPa compared to 21.3 and 48 MPa for the shear strength. The values for all groups was significantly different (p<0.001). There was no significant correlation between the shear bond strength and the fatigue limit values (Pearson Correlation P<0.01). For all groups, the threshold stress at which the samples equid withstand over one million cycles (fatigue Life) was 2.5 MPa. For ceramic to enamel bonds, the fatigue limit (after 5000 cycles) varied between 11.41 and 13.74 MPa compared to 21.3 and 48 MPa for the shear strength. The values for all groups were significantly differ~nt (p<0.001). There was no significa~t correlation between the shear bond strength and the fatigue limit values (Pearson Correlation P<0.001). For all groups, the threshold stress at which the samples could withstand over one million cycles (fatigue Life) was 2.5 MPa. Conclusion: Fatigue damage to the surface and subsurface of composite was related to the hardness of the material. The values of the fatigue limit were significantly lower than the shear bond strength values. There was no correlation between fatigue limit and shear bond strength. The long term safety limit for resin bonded joints to enamel is 2.5 MPa. Neither the shear test, nor the fatigue limit test was an accurate predictor of the long-term fatigue behaviour of resin-bonded restorations. A fatigue limit test using 100,000 cycles may be a useful predictor of the fatigue life which, in these studies, was half of the fatigue limit at 100, 000 cycles but the only reliable test is to test to failure. The data presented in this thesis indicated that the shear bond strength is not pred!ctor of long term failure. lClearfil Posterior, Cavex. Holland. 20cclusin. ICI. UK. 3Concise, 3M.

Abstract (sommario):

Many dental devices combine acrylic (i.e. poly-methyl methacrylate or bisphenol A-glycidyl methacrylate) and metallic parts (i.e. titanium or stainless steel) that are bonded together. These devices often present catastrophic mechanical failures due to weak bonding between their acrylic and metallic components. These devices include dental prostheses, combining metallic frameworks (i.e. titanium) and wrought wires with acrylic resin; and orthodontic appliances, combining acrylic resin with stainless steel wrought wires or composite with stainless steel brackets. The bonding between metals and polymers in dental devices is usually performed by the mechanical interlocking, but its bond strength is still too low for dental applications. The bond strength between them would be high if the chemical bonding, which does not occur spontaneously, uses in addition to the mechanical interlock. The objective of this study was to develop a new method of creating a strong chemical bond between alloys and polymers for dental devices based on diazonium chemistry.The chemical bond between metals (i.e. titanium or stainless steel) and polymers (i.e. poly-methyl methacrylate, PMMA or Bisphenol A-glycidyl methacrylate, Bis-GMA) was achieved in two steps. In the first reaction step (primer), the aryldiazonium salts were chemically reduced to form aryl radicals which spontaneously got grafted onto the metallic surfaces. The second step of the reaction (adhesive) was optimized to achieve covalent binding between the grafted layer and PMMA or Bis-GMA. The chemical composition of the treated surfaces was analyzed with X-ray photoelectron spectroscopy (XPS), and the bonding strengths between alloys and PMMA or Bis-GMA were measured. XPS characterization and contact angle measurement confirmed the presence of a polymer coat on the treated metallic surfaces. Whereas, the mechanical test results showed a significant increase of the tensile bond strength between PMMA and treated titanium or stainless steel wire by 5.2 and 2.5 folds, respectively, compared to the untreated control group (P<0.05). Moreover, the bonding strength between metallic brackets and Bis-GMA composite was increased after the treatment depending on the bracket design by 2 to 3.9 folds compared to untreated brackets. Diazonium chemistry provides an effective way of achieving a strong chemical bond between alloys and PMMA or Bis-GMA. The resulting bonding method can be utilized to further improve the properties of dental devices, reduce debonding of dental prostheses and brackets, provide more leverage in orthodontic cases with complex mechanics, and allow the use of brackets with smaller bases.
De nombreux appareils dentaires sont composés d'acrylique (c'est à dire d'un poly -méthacrylate de méthyle ou de bisphénol A- glycidyle méthacrylate) et de parties métalliques (par exemple en titane ou en acier inoxydable) qui sont collés ensemble. Ces dispositifs présentent souvent des défaillances mécaniques catastrophiques en raison de la faiblesse de la liaison entre les composantes en acrylique et celles en métal. Ces dispositifs comprennent les prothèses dentaires, alliant des cadres métalliques (c'est à dire de titane) et fils forgé avec de la résine acrylique, et les appareils orthodontiques, combinant de la résine acrylique avec des fils forgé en acier inoxydable ou un composite avec des supports en acier inoxydable. La force de liaison entre eux serait élevée si la liaison chimique, ce qui ne se produit pas spontanément, est utiliser en plus du verrouillage mécanique. Dans la première étape de la réaction, les sels d'aryl diazonium sont réduits chimiquement pour former des radicaux aryles qui sont spontanément greffés sur les surfaces métalliques La deuxième étape de la réaction a été optimisée pour réaliser la liaison entre la couche greffée et le PMMA ou le Bis-GMA. La caractérisation XPS et la mesure de l'angle de contact a confirmé la présence d'une couche de polymère sur les surfaces métalliques traitées. Les résultats des essais mécaniques ont montré une augmentation significative de la force d'adhérence à la traction entre le PMMA et le titane traité ou d'un fil en acier inoxydable de 5,2 et 2,5 plis, respectivement, par rapport au groupe témoin non traité (p < 0,05). La chimie de diazonium fournit un moyen efficace d'atteindre une liaison chimique forte entre les alliages et le PMMA ou le Bis-GMA. Le procédé de collage qui en résulte peut être utilisé pour améliorer les propriétés des appareils dentaires, réduire le décollement de prothèses dentaires et des supports, et permettre l'utilisation de supports avec des bases plus petites.

Abstract (sommario):

The demand for posterior aesthetic restorations has dramatically increased in recent years. Several new materials have been developed with improved aesthetic, adhesive and mechanical properties. However, microleakage elimination, especially if the margins are on dentine or cementum, and attainment of optimum mechanical properties for posterior use, are still questionable. The aim of this study was to investigate microleakage and surface microhardness of a nanofilled, a nanohybrid and an ormocer based nano-ceramic composite restorative material.

Magister Scientiae - MSc
Amalgam bonding agents have been shown to enhance retention of amalgam restorations by mechanical means. However, recent studies showed that the use o glass ionomer cements and resin cements as lining and bonding materials to amalgam restorations will increase the retentive strength of the amalgam restorations, hence reducing the micro leakage and secondary caries. The purpose of this study was to compare the relative retentive strength of conventional amalgam restorations and bonded amalgam restorations using resin adhesive, glass ionomer cements and resin cements.

Abstract (sommario):

Over 200 million dental restorations are performed each year in America. A dental restoration require a strong bonding of restoration to tooth structure and relies on the dental adhesive to create this mechanical and chemical bonding. Dental adhesion or bonding is the process of forming an adhesive joint between the composite and tooth substrate: dentin or enamel. Clinical problems such as microleakage at the restoration tooth interface, influx of fluids, or bacteria growth at the cavity wall can be prevented with adhesives that obtain a more intimate bonding. Longevity of the restoration can be enhanced by the adhesive that creates the tight bonding to reduce problems such as postoperative sensitivity, marginal staining, and recurrent caries. The goal of this research project is to investigate the influence of active scrubbing application as compared to passive non-scrubbing application of the etchant component in 4th generation etch-and-rinse adhesive systems. Shear bond stresses have been measured and compared between application techniques. Verification of resin infiltration depth with each etchant application has been examined with scanning electron microscopy by mounting the etched and bonded enamel surface of the tooth in epoxy and slicing the tooth longitudinally producing a transverse, depth-wise view. Results from this study have clarified the role of resin tag formation as well as tooth morphology during an active acid etchant application for dental restoration.

PURPOSE: To evaluate the effect of aqueous solutions of chlorhexidine digluconate (CHX) in different concentrations on bond strength to eroded dentin up to 6 months, using normal dentin as a control. METHODS: Exposed flat dentin of extracted third molars was only ground with 600-grit SiC paper/1 minute (normal dentin - N), or subsequently eroded by a regular-cola soft-drink (eroded dentin - E). N and E were acid-etched, washed, dried and rehydrated with 1.5 μL, respectively, of distillated water (control - NC / EC); of 0.004% CHX (N0.004% / E0.004%); or of 2% CHX (N2% / E2%). Adper Single Bond 2 was applied in all specimens and resin composite buildups were constructed with Filtek Z350. Specimens were sectioned in beams, which were tested (μTBS) immediately or after 6 months of aging. RESULTS: Microtensile bond strength to eroded dentin was always significantly lower than that to normal dentin. Application of tested CHX solutions did not exert a significant effect immediately; however, after aging, the 2% CHX prevented abrupt bond strength loss both to eroded and normal dentin.
