Wettability of Dentin Structure after Exposure ... with high radiant power and extended lifetimes which might be particularly useful in dentistry. Therefore, adequate parameters should be chosen to achieve proper therapeutic benefits. MG-63 osteoblast-like cells were cultured on the altered surfaces to study proliferation, and for ultrastructural analysis and immunocytochemical characterization. Fluoride did not modify the contact angles, but increased the roughness of the finished material. Wettability and roughness are dentin substrate conditions that are critical to establishing good adhesion. A contact angle analyzer, Vickers hardness tester, and spectrophotometer were used to characterize the … All acrylics and composite resins produce an exothermic reaction during the polymerization process. Wettability of both sealers is the worst on EDTA-irrigated dentine. Bis-acryl based composite resins generated a significantly lower degree of heat during polymerization, making them the material of choice to potentially minimize thermal injury to the dentin-pulp complex. They gather age-related diseases and become ‘frail’, i.e. HCP and HC cement had similar fibroblast compatibility and significantly higher than the others (p≤ 0.05). Results: The 100 top-cited articles most frequently for the work done with SBS in the field of dentistry, 24 articles are the most common areas of orthodontics, while 17 articles are the areas of prosthetic dentistry and general dentistry. Adjustment of ultrashort pulsed laser parameters can, therefore, significantly alter dentin surface roughness and wettability. Addition Silicones – Addition silicones are the most popular type of elastomeric impression material, especially for crown and bridge impressions.

NLM However, chipping of fused feldspathic veneers on the zirconia cores is prone to limit the use of YSZ in all-ceramic dental restorations. Contact angle increased as surface roughness in metal specimens decreased, but decreased as surface roughness in resin specimens decreased (p<0.0001). Atomic force microscopy was used to measure the surface roughness (Ra). Furthermore, all ablated dentin showed a contact angle of approximately 0 deg, meaning that laser ablation significantly improved wettability. The wettability of the surface plays an important role with respect to protein adsorption, cell attachment, and spreading. The equilibrium and hysteresis angles obtained were used for the comparisons. Without chitosan (HP); 4. One side of the specimens was subjected to standard polishing (pumice and whiting slurry), and the opposite side was polished with special tips. Its advantages derives from implants' characteristics (smaller diameter, variable length, O-ring retention system), which adapts better to the particular edentulous conditions. ... First is wettability. Several parameters are registered using the tablet. Either ceramic materials or resin composites are used for indirect esthetic restoration. Untreated cell culture for method 1 and a ceramic specimen for method 2 served as a positive control, liquid PMMA for both methods was used as a negative control. Objectives: The aim of this in vitro study was to evaluate the wettability of AH Plus and ThermaSeal Plus sealers on intraradicular dentine treated with different irrigating solutions. Wettability correlates with surface tension on ideal surfaces (chemically Based on the contact angle data, the following can be observed: the contact angles obtained by both the finishing and non-finishing groups were influenced by the pH value ( p <0.05). Biocompatibility was tested by evaluating the cytotoxicity using the agar-overlay-test, measuring succinic dehydrogenases activity (MTT-Assay) and detecting adenosine triphosphate (Cell-Titer-Glo-Assay). Samples in groups 1 to 8 were ablated with an ultrashort pulsed laser through a galvanometric scanning system. 4. The first elastic dental impression material was the hydrocolloid, which was introduced to dentistry in 1925. Search for more papers by this author. In this case oxidized silicon pieces were etched with caustic solutions to produce different degrees of nanoroughness.

The wettability of impression material affects the number or volume of air bubbles generated during the pouring of gypsum casts. Author information: (1)Oral Surgery and Implant Dentistry Department, School of Dentistry, University of Granada, Campus de Cartuja S/N, ... and subsequent tissue behavior. Roughness changed the contact angles, especially those of Ariston (α < 0.05). Complete cement (HCP) with nHA, zinc oxide-magnesium, and chitosan; 2. cement without nHA (CP); 3. Effect of disinfection and sterilization on the tensile strength, surface roughness, and wettability of elastomers. Samples in groups 9 and 10 were prepared with grinding instruments. Additionally, the influence of nanoroughness, and the subsequent effect of hysteresis on cell behavior, was also analyzed. J Biomed Mater Res A. The research has shown that the process of sandblasting and HF acid-etching influences the change on physicochemical properties of zirconia surface, its topography and wettability. The first elastic dental impression material was the hydrocolloid, which was introduced to dentistry in 1925. Wetting is the ability of a liquid to maintain contact with a solid surface, resulting from intermolecular interactions when the two are brought together. Results: All CAD/CAM-machinable materials tested with the agar-overlay were found to be non-toxic, whereas the established provisional materials ranked from non-toxic to mild-toxic. This study was supported by the Forschungsgemeinschaft Dental e.V. composite materials, orthodontic adhesives and appliances, prosthodontic resins and impression materials, have all been involved. Following ablation and preparation, the samples were examined for contact angle with an optical contact angle measuring instrument. PUBMED, Web of Science Core Collection, Google Scholar were the scientific databases used to establish the usage frequency of the indices OHIP, GOHAI, OIDP, DIDL, OHQoL-UK in researches on elderlies. The purpose of this study was to investigate on human dentin the relationships between, on the one hand, the wettability of five adhesive compounds, characterized by different solubility parameters delta, and on the other, the thickness of the resin impregnated dentin layer (RIL) and the shear bond strength (SBS). The study consisted of the wettability angle measurement, Atomic Force Microscopy (AFM), X-ray Diffraction (XRD) and Scanning Electron Microscopy (SEM). Thirty human extracted teeth were sectioned into crowns and roots along the cementum–enamel junction, and then the crowns were cut longitudinally into sheets about 1.5 mm thick.

The established materials for provisional restorations showed slightly lower levels of cell-viability but no significant cytotoxicity. The samples were randomly divided into ten groups (n = 3/group). The appropriate connection of the porcelain with abutment can be achieved by modifying the outer surface of the ceramics. Such recognition should bring about more realistic teaching in the dental schools and more rational procedures in dental practice.The occlusion for complete dentures should be balanced “at and near” centric jaw relation for protection of the ridges when there is no interposed food. The surface roughness of samples from each group was then measured using a three-dimensional profile measurement laser microscope, and wettability was evaluated by measuring the contact angle of a drop of water on the prepared dentin surface using an optical contact angle measuring device. In order to evaluate thermography in exploring the oral mucosa of denture wearers and dentate subjects, a pilot study was conducted where two mobile denture situations and a dentate one were analyzed using infrared thermography. In general, tooth-colored materials require incremental thicknesses to ensure adequate color and sufficient mechanical properties. The aim of this study is to evaluate a novel, objective, observer-independent and assistance-independent tablet device-based method which could be helpful in the upper limb function diagnostics designed for telemedicine technology and frailty assessment. The adherence of Streptococcus sanguis ATCC 10556, S. sanguis ATCC 10557, S. mutans Ingbritt, and S. mutans OMZ 176 to the surfaces of composite resins, amalgam alloys, and a Au-Ag-Pd alloy was measured. The wettability results (means and standard deviations) and statistical comparisons are summarized in Table 2. This study was done to determine the effect of various commercial disinfectant solutions on the wettability of elastomeric impression materials. Novel non-thermal plasma (NTP) technology has the potential to address this issue. Methods: Samples for 5 materials were prepared and stored dry or wet in deionized water pH 6.8. 2018 Jun;5(3):159-166. doi: 10.1093/rb/rby009. For deep dentin, collagen removal did not influence the average roughness, but it resulted in a significantly greater degree of wettability. The results showed that both laser fluence and PO had an effect on dentin surface roughness. FRCs vary according to the type of fiber fillers and orientation of fibers, the latter being responsible. Significance The slightly neutral medium is necessary to decrease the inflammatory response and also to accelerate the deposition of apatite in a similar way as observed for bones. Abstract Statement of problem Extended contact of impression materials with chemical disinfectant could remove surfactant, significantly altering the contact angle and wettability characteristics of an impression material.
