Novel non-thermal plasma (NTP) technology has the potential to address this issue. However, in practice a dynamic phenomenon of … The high polarity obtained on Y-TZP and Ti surfaces after NTP applications appear promising to enhance resin bonding. Some of the results are very relevant and have a major impact on human life and have already been adapted [2]. Reactions to metals used in extra-oral appliances in orthodontics seem to be relatively frequent, but few reactions have been reported following the use of other alloy systems. Nowadays aesthetic plays a very important role in prosthetic restorations. Lopes et al., Dentistry 215, 5:3 9 1.12/2111122.123 Research Article pen Access Dentistry ©½ºÃ»³ Ú ÁÁó Ú ¦¦¡ Dentistry, an open access ournal Wettability of Irrigants used in Root Canal Treatment Hélio P Lopes 1, Adenilza R De Faria , Flávio RF Alves * and Carlos N Elias2 1Department of Endodontics, School of Dentistry, Estacio de Sa University, 580, Alfredo … Adhesion was correlated with values for hydrophobicity and zeta-potential of the bacteria and the restorative materials. Although these two factors appear inconsistent, patients unquestionably require both to be provided with high quality care that will include both solutions in the context of a well-organized and sequenced comprehensive treatment plan. Samples of groups 9 and 10 were prepared with grinding instruments. Oral health is an important part of human health. Long-term clinical observations have shown that the restorations on the zirconia abutments are often accompanied by destructive incidents such as chipping and cracking of the ceramics or fractures in the abutments. The aim of this study was to determine if the removal of the collagen fibers results in changes in dentin roughness and wettability. Wettability and roughness are dentin substrate conditions that are critical to establishing good adhesion. Surmeneva M, Nikityuk P, Hans M, Surmenev R. Materials (Basel). However, the influence of titanium surface roughness and hydrophilicity on fibroblast behavior is not well understood. Laser modified the organic matrix layer. The samples were randomly divided into ten groups (n = 3/group). Li B, Gao Y, Guo L, Fan Y, Kawazoe N, Fan H, Zhang X, Chen G. Regen Biomater. It also examines the relationship between wettability and the friction factor for multiple lubricant-surface pairings. Five 20 x 3 ± 1 mm diameter discoid specimens were obtained for each group. --New York University College of Dentistry, 2001. Evaluation of some morphological oral aspects perceived as decision factors in complete edentulism treatment by mini-implants overdenture. 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). Specifically, a higher PO decreased dentin surface roughness and reduced the effect of high-laser fluence on decreasing the surface roughness in some groups. In addition to surface topography, the properties of implant materials that affect cellular behavior include mechanical rigidity and wettability (SFE). The established materials for provisional restorations showed slightly lower levels of cell-viability but no significant cytotoxicity. To present an overview of fiber-reinforced composites (FRCs) that are a group of non-metallic dental biomaterials used in several fields of dentistry. Method. Furthermore, wettability has an essential role in developing a suitable contact time of an irrigant with dentinal walls. 2018 Jun;5(3):159-166. doi: 10.1093/rb/rby009. Search for more papers by this author. 22 Erkut S, Can G. Effects of glow-discharge and surfactant treatments on the wettability of vinyl polysiloxane impression materials. By rigorous selection of the polyurethane matrix, it is possible to obtain polymers with great potential of advanced materials. 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. Maxillofacial prosthetic materials that contact skin or mucosa should have good wettability. Both at 0.2 and 0.3 mm deflections, the lowest load required to bend the retainer was recorded for spot-bonded stainless steel flat and round wires and for spot-bonded FRCs, and no significant differences were identified among them. Wettability of Irrigants used in Root Canal Treatment Author: Lopes, Helio P Journal: Dentistry Issue Date: 2015. Wettability was the predominant factor for S. … HCP and HC cement had similar fibroblast compatibility and significantly higher than the others (p≤ 0.05). Insertion technique implies less surgical trauma. J Biomed Mater Res A. However, the thick form of a prosthesis contradicts the concept of "minimal intervention". The zinc oxide-magnesium presence was important to improve the mechanical strength. Other frequently used indices for this Wettability of both sealers is the worst on EDTA-irrigated dentine. Reduction of contact angle reading from 15o (baseline) to 0o was obtained when the MDP primer was placed on NTP treated Y-TZP. In the present study, five dental polymers were investigated to ascertain their contact angles, wettability, roughness, and fluoride release in dry or wet conditions. All rights reserved. After conducting the sandblasting and acid-etching manipulation of the zirconia surface, the wettability angle corresponds with poorly wettable materials, which are characterized by hydrophobic properties. Higher force levels were reported for full-bonded metallic flat and round splints and the highest loads were recorded for full-bonded FRCs. These Start studying Dental Materials Definitions (First 3 Chapters). There were no significant differences in the surface energies of the silicone rubber materials, but all were significantly lower than denture acrylic resin material. The forces involved in surface tension, surface wetting, chemical … Different laser parameters were used including different fluences (F), scanning speeds, and scanning line spacings. A handheld NTP device (KiNPen 09, neoplasm tools GmbH, Germany) was used to treat the disc surfaces followed by SE evaluation (OCA 30, DataPhysics, Germany) through the OWRK method. Methods: Y-TZP and Ti discs (10 X 2 mm) were distributed across four, Objectives An observational study was conducted on a sample of 24 patients (average age of 61 years), through clinical and imagistic methods. ADHESION IN DENTISTRY INTRODUCTION: After observing the industrial use of phosphoric acid to improve adhesion of paints and resin coatings to metal surfaces, Buonocore, in 1955, applied acid to teeth to “render the tooth surface more receptive to adhesion”. Specimens were distributed according to methods of carious removal (n = 39): bur at low‐speed (40,000 rpm) or Er:YAG laser (noncontact mode, 250 mJ/pulse and 4Hz). Twenty cary‐free extracted human third molars were sectioned parallel to the occlusal surface to expose either superficial or deep dentin. For deep dentin, collagen removal did not influence the average roughness, but it resulted in a significantly greater degree of wettability. The experimental cement showed antimicrobial activity against P.g, F.n, A.a, and S.aon the diffusion agar test higher than control cement (17.6 ± 1.1 mm) p≤ 0.05. The variables taken into consideration were: age, gender, alveolar mucosa status, bone offer, mini-implants characteristics, insertion torque and loading type. A contact angle analyzer, Vickers hardness tester, and spectrophotometer were used to characterize the … Published by Elsevier Ltd. All rights reserved. Materials and Methods: Specimens from three different polymers for CAD/CAM use (Artbloc-Temp, Merz Dental; CAD-Temp, Vita; C-Temp, Kavo) and three different established materials for provisional fixed restorations (Luxatemp, DMG; Prevision, Hereaus; Protemp, 3MEspe) were prepared and tested on human oral epithelial cells. The adsorption of bovine serum albumin (BSA) on surfaces of dental enamel and of dental materials was investigated by scanning force spectroscopy. Abstract. Wetting characteristics of denture lining materials indicate the degree of salivary lubricating effect, which promotes denture retention and patient comfort. Its advantages derives from implants' characteristics (smaller diameter, variable length, O-ring retention system), which adapts better to the particular edentulous conditions. In this case oxidized silicon pieces were etched with caustic solutions to produce different degrees of nanoroughness. The physicochemical characterization showed an expected pattern from the raw materials and composition. Clinical significance The present study highlights the effect of newer endodontic irrigating solutions on the wettability of sealers on to the root canal dentine, which is required for obtaining good obturation seal. Clipboard, Search History, and several other advanced features are temporarily unavailable. Either ceramic materials or resin composites are used for indirect esthetic restoration. The test employs a tablet and a fixed-height obstacle. This study showed that various laser fluences, scanning speeds and scanning line spacings can affect and alter enamel surface roughness. Some reactions may be due to toxic or allergic effects, but some are unexplained. Four denture base materials, two denture hard lining materials, and three denture soft lining materials (with and without varnish treatment) were tested. The wettability of the surface plays an important role with respect to protein adsorption, cell attachment, and spreading. Prevalence of root resorption is higher when there are alterations of the normal anatomy (facial hypo- or hyperdivergence, Angle class II and III malocclusion, angulated roots). In general, tooth-colored materials require incremental thicknesses to ensure adequate color and sufficient mechanical properties. mimic surface and interface properties of natural tissues. While the fields of tissue engineering and regenerative medicine have hinted at much promise over the last few decades, significant amount of research is still required with the field of nanotechnology to innovate new exciting materials that can overcome drawbacks of the existing biomaterials. The solder's capability of effectively wetting the alloy is another requirement for a successful soldering process. At the maximum load, no significant differences were reported among spot- and full-bonded metallic splints and spot-bonded FRCs. 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). The hydrophobicity of the restoratives showed a positive correlation between the numbers of adherent S. sanguis cells, suggesting that hydrophobic interactions are important for the adherence of this bacterial species. The equilibrium contact angle ranged from 59.9 to 77.3 degrees, and contact angle hysteresis ranged from 14.7 to 30.6 degrees. Increasing the nanometer surface roughness or water contact angle enhanced osteoblast behavior in terms of cell morphology, proliferation and immunophenotype, the effect provoked by methylation being more significant than that caused by nanoroughness. 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. Front Bioeng Biotechnol. Nanoscaled periodic surface structures of medical stainless steel and their effect on osteoblast cells. Wettability (n=5) was determined by measuring the static contact angle of a sessile drop of distilled water in an automatic goniometer (Dataphysics, OCA20, Filderstadt, Baden-Württemberg, Germany). Kozelskaya AI, Bolbasov EN, Golovkin AS, Mishanin AI, Viknianshchuk AN, Shesterikov EV, Ashrafov А, Novikov VA, Fedotkin AY, Khlusov IA, Tverdokhlebov SI. This study aimed to quantitatively evaluate the surface roughness of enamel following ablation with a Yb:KYW thin-disk femtosecond pulsed laser at different fluences (F), scanning speeds and scanning line spacings. Atomic force microscopy was used to measure the surface roughness (Ra). Materials and Methods: Dentin surfaces of third human molars were Er:YAG laser- and bur-prepared to evaluate the effects of surface tension and roughness on wettability … This work presents a meta-analysis that compares the suitability of various parameters used to characterize wettability in tribological systems. The microhardness of G1 and G3 resins showed statistical differences. Roughness changed the contact angles, especially those of Ariston (α < 0.05). Ten soft and hard visible light-curing materials, one autopolymerized hard lining material, and one autopolymerized denture base material were evaluated for wettability. applying the same principles to different situations. The effect of the hard and soft segments concentrations, polyols nature and chain extender structures on the polymers has been discussed with respect to thermal, mechanical and wetting properties. Therefore, adequate parameters should be chosen to achieve the proper therapeutic benefits. 2016 Oct 25;9(11):862. doi: 10.3390/ma9110862. Epub 2018 Sep 27. The formulations prepared were: 1. Contact angles and surface energies were measured by using a dynamic contact angle measuring technique. Furthermore, NVC-containing polyelectrolytes are better dentin conditioners than a commercially available dentin conditioner (GC dentin conditioner). Methods It is expected that nanodentistry will eventually give rise to highly efficient, effective, and personalized dental treatment [2]. Enhancement of Intracellular Calcium Ion Mobilization by Moderately but Not Highly Positive Material Surface Charges. Auch muß heute die enossale Implantologie für einzelne Fälle als Platzhalter berücksichtigt werden. Ceramics, as a biocompatible material, are very willingly used in dental prosthetics. Without zinc oxide-magnesium (HC), and CPZn as control. Choosing implants' size, number, topography, and the loading method have a great variety, depending on anatomical feature (bone offer, mucosa and relationship with the nearby anatomical structures), functional features and patients' wishes. The synthesized terpolymer was used in glass-ionomer cement formulations (Fuji IX GP). The highest prevalence of root resorption was found in the lower central incisor (86%). Only in 16.67% of patients was possible the transmucosal insertion. Alginate was found to be the most hydrophilic material, but this quality decreases in time. This site needs JavaScript to work properly. Some features of this site may not work without it. Thus, thermography may be a method of polymer-oral status interrelation assessment in denture wearers, providing important information in prevention, diagnosis and treatment of oral diseases, acquired in relation to polymer dentures.
