Texte intégralThe present work concerns research and development of a material for bone substitution, enabling implantation through a mini-invasive surgery, limiting post-operative infections and whose resorbability is adapted to bone regeneration kinetics. This study focused on a calcium carbonate and phosphate based cement, whose setting reaction leads to the formation of a nanocrystalline apatite, similar to bone mineral. First, the setting kinetics and the reaction products were characterised using different techniques, especially X-ray diffraction and FTIR and solid-state NMR spectroscopies. A silver salt – Ag3PO4 or AgNO3, chosen for their antibacterial properties – was then introduced in the formulation. Its effect on the setting reaction kinetics was revealed by data processing of FTIR and NMR spectra and an original reaction mechanism which involves silver and nitrates in the formation of apatite was proposed. The addition of a polysaccharide, carboxymethylcellulose (CMC), in the solid phase of the cement showed a clear improvement of the injectability of the paste, preventing the occurrence of filter-pressing phenomenon, often limiting the injectability of mineral cements. The resistance to compressive strength and elastic modulus of the composite cement were also improved together with a decrease in their porosity. Different in vitro studies were carried out in the presence of cells or bacteria and demonstrated the cytocompatibility of different cement compositions and their antibacterial properties starting at a certain silver concentration, respectively. In vivo implantation of selected compositions showed promising results concerning resorbability of a composite CaCO3 - CaP/CMC/Ag cement and the associated bone neoformation

Texte intégralRadiopacity is an important pre-requisite for base and liner materials, once it allows the professional to identify the presence of the material and makes its differentiation from the adjacent tooth structure possible. The aim of this study was to evaluate the radiopacity of liner and base materials and compare to the radiopacity of enamel, dentin and aluminum stepwedge. For this, 16 glass ionomer cements, 8 flowable resin composites and 4 calcium hydroxide cements were analysed. It was prepared three sets of three test specimens with 4 mm in diameter and thicknesses of 1, 2 and 3 mm for each glass ionomer cement and flowable composite and 1 mm for each calcium hydroxide cement. Cross sections were made from crowns of three third molars to obtain specimens of enamel and dentin with thickness of 1, 2 and 3 mm. As a control, a standard aluminum stepwedge with nine steps was used. Radiographs were taken with digital Kodak RVG 5000 (Kodak Company, France) and exposure time of 0.32 seconds. The images were analysed through the program Image Tool ® to obtain the mean grey values. Statistical test ANOVA followed by Tukey test (p 0.05) detected significant differences between the materials of the same category and between the thicknesses. The commercial brands Ionomaster, Maxxion, Bioglass R, Bioglass F, Vidrion R and Vidrion F, presented radiopacity lower than the radiopacity of dentin, insufficient for a correct diagnostic. All flowable resin composites and calcium hydroxide cements studied showed radiopacity superior than dentin. Vitro Fil, Magic Glass, Vitrebond, Riva SC, Riva LC, Fill Magic, Opallis, Surefil, Tetric N, Tetric, Hydro C, Hydcal and Liner showed radiopacity equal to or greater than the enamel for all thicknesses. In general, the increased thickness of the materials studied increases its radiopacity significantly. It was concluded that some materials indicated as base and liner for restorations have and inadequate radiopacity to be detected radiographically.

Texte intégralPolymerization shrinkage leads to a tension into dentin/resin composite interface that can cause marginal discoloration, poor marginal adaptation, secondary caries and post-operative sensitivity. The incremental restorative technique and the use of a resilient liner with a modulus of elasticity similar to dental structures are techniques used to decrease the shrinkage polymerization tension. The aim of this in vitro study was to analyze the effect of glass-ionomer cement as a liner on the adhesive interface dentin/resin of occlusal restorations after thermocycling aging. Occlusal cavities were prepared sixty human extracted molars, divided into six groups: 1 and 4 with no liner; 2 and 5 glass-ionomer cement (Ketac Molar Easymix); and 3 and 6 resin-modified glass-ionomer cement (Vitrebond). Resin composite (Filtek Z250) was placed after application of adhesive system Adper Single Bond 2. Adhesive system was mixed with fluorescent reagent (Rhodamine B) to allow confocal microscopy analysis. After that, the specimens of groups 4, 5, 6 were thermocycled into 2 baths (5ºC 55ºC) of 30s each in 5.000 cycles. After this period, teeth were sectioned in 0,8mm slices. One slice of each tooth was randomly selected for analysis in Confocal Microscopy. The other ones were sectioned in sticks, which were submitted to micro-tensile test. The results of adhesive strength were analyzed by one way ANOVA and t-Student tests. Gap formation were analysed by Fisher test and the gaps size were analyzed by Kruskal-Wallis test (p<0,05). No statistical difference on adhesive resistance was showed between groups. Confocal Microscopy analysis showed gaps with a higher mean sizes for group 4 (12,5µm) and higger percentage of marginal gaps formation for the thermocycled groups (G1 - 30%; G2 - 25%; G4 - 53,33%; G5 70%). Groups 3 (25%) and 6 (30%) showed the lowest percentage of marginal gap formation. The results revealed that gap formation is not related to adhesive strength. It can be concluded, therefore, that the use of a resin-modified-glassionomer cement liner showed less gap formation on dentin/composite adhesive interface after artificial aging compared to conventional glass ionomer cement liner and restorations with no lining.

Texte intégralThe aim of this study was to evaluate the effect of resin-modified-glassionomer linning and incremental technique on the bond strength of the composite restoration interface. Methods: Cavities were made (4.5mm X 3mm X 5mm) in 52 extracted human molars, divided into 4 groups: Group 1 (control) no linning + two horizontal increments (C Factor = 5); Group 2: no linning + four oblique increments (C Factor = 2); Group 3: RMGIC linning (Vitrebond) + two horizontal increments; and Group 4: RMGIC linning (Vitrebond) + four oblique increments. All teeth were restored with Adper Single Bond and Filtek Z250 and stored in deionized water at 37ºC for 24 hours before sectioned into 0.8 mm sticks (bucco-lingually). One slice of each tooth was randomly selected for confocal microscopy for analysis of the interface resin/dentin. The other slices were sectionated in sticks (mesio-distally) for microtensile test in a Universal Testing Machine (EMIC) at 0.5mm/min. The data were analyzed by Two-way ANOVA (5%) and Fishers test for variables of presence of gap. No statistical difference on adhesive strength among groups (G1 14.55 ± 4.228 MPa, G2 17.25 ± 7.31 MPa, G3 12.81 ± 4.97 MPa and G4 13.39 ± 4.115 MPa). No significant statistical difference was observed regarding the presence of gap at the interface dentin/resin among groups (p>0.05). It can be concluded, that resin-modified glass-ionomer cement linning and resin composite techniques showed no effect on the adhesive interface to dentin.
