The primary objective of a restoration is to recover functional occlusion. Department of Restorative Dentistry, Piracicaba Dental School, University of Campinas, Piracicaba, SP, Brazil. This work presents a meta-analysis that compares the suitability of various parameters used to characterize wettability in tribological systems. Higher force levels were reported for full-bonded metallic flat and round splints and the highest loads were recorded for full-bonded FRCs. The purpose of this study was to investigate the influence of the surface roughness of denture base resin and metal on wettability with water and saliva. The wettability results (means and standard deviations) and statistical comparisons are summarized in Table 2. However, the thick form of a prosthesis contradicts the concept of "minimal intervention". In addition to surface topography, the properties of implant materials that affect cellular behavior include mechanical rigidity and wettability (SFE). One side of the specimens was subjected to standard polishing (pumice and whiting slurry), and the opposite side was polished with special tips. Conclusions. Adhesion of restorative and protective materials to dentin is an important requirement for operative and preventive dentistry. Polymeric material shows a similar temperature rise to the mucosa (thermal impression) and residual heat. 2009 May;89(2):453-65. doi: 10.1002/jbm.a.31979. Wettability of both sealers is the worst on EDTA-irrigated dentine. Understanding the anisotropic nature of FRCs from the perspective of dental applications has increased in recent years. The first elastic dental impression material was the hydrocolloid, which was introduced to dentistry in 1925. CHI promoted partially closed tubules in some areas while EDC exposed dentinal tubules. Silicone impression materials, however are recognized as having poor surface wettability.1 Clinically, the topical use of a surface wetting agent has been demonstrated to improve wettability and significantly reduce the number of voids in … The length of the fibers, i.e. Introduction: The aim of this “in vitro” study was to evaluate the role of surface tension and surface roughness in the wettability, considered essential for a good adhesion, comparing Er:YAG laser - to bur-prepared dentin. Separate Y-TZP and Ti discs (n=1 each) were NTP treated and a drop of MDP primer was dispensed at 3 points on each surface for contact angle readings. They were cleaned to reveal the tubules, and the morphological features of each surface were … Oral health is an important part of human health. 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). 2019 Apr;34(3):537-546. doi: 10.1007/s10103-018-2626-2. Alginate was found to be the most hydrophilic material, but this quality decreases in time. Methods: Y-TZP and Ti discs (10 X 2 mm) were distributed across four, Objectives To present an overview of fiber-reinforced composites (FRCs) that are a group of non-metallic dental biomaterials used in several fields of dentistry. The movement or flow of a liquid causes a resistance to the force that is trying to move it. 2020 Sep 8;8:1016. doi: 10.3389/fbioe.2020.01016. Clinical Relevance The effect of pH on the wettability and fluoride release of Ariston pHc was examined. Li B, Gao Y, Guo L, Fan Y, Kawazoe N, Fan H, Zhang X, Chen G. Regen Biomater. Acta Biomater. Only in 16.67% of patients was possible the transmucosal insertion. The biggest variations on the zirconia surface were obtained after etching with hydrofluoric acid. They gather age-related diseases and become ‘frail’, i.e. The soft liners showed greater contact angle hysteresis than all other materials. Wettability, or wetting, which is a material’s ability to spread over a surface, 4 strongly affects the accuracy of an impression material. Materials and Methods: This study was conducted to obtain citation information on SBS articles by using the Science Citation Index (SCI) and the Extended Science Citation Index (SCI-E) from Web of Science. Results: Significant augmentation of SE values was observed in all NTP treated groups, dictated by the increase of the polar component. Twenty cary‐free extracted human third molars were sectioned parallel to the occlusal surface to expose either superficial or deep dentin. on wettability and adhesiveness a study of enamel dentine some restorative dental materials and dental plaque Oct 07, 2020 Posted By Jin Yong Media TEXT ID 310967ea6 Online PDF Ebook Epub Library author see sep 06 2020 on wettability and adhesiveness a study of enamel dentine some restorative dental materials and dental plaque posted by wilbur smithlibrary text id Wettability of Dentin Structure after Exposure ... with high radiant power and extended lifetimes which might be particularly useful in dentistry. The purpose of this investigation was to evaluate the wettability changes of polyether impression material after immersing in four different chemical disinfectant solutions for a period of 10 min and 30 min, respectively. Numerical values corresponding to the thermograms showed an increased temperature underneath prostheses with different distribution in oral mucosa, corresponding to the clinical picture. Acrylic resins used for provisional prostheses should have satisfactory superficial characteristics in order to ensure gingival health and low bacterial attachment. NVC-containing terpolymers may enhance the surface properties of GICs and increase their bond strength to the dentin. chemistry and wettability of dental implants Suelen Cristina SARTORETTO 1, Adriana Terezinha Neves Novellino ALVES , Rodrigo Figueiredo Britto RESENDE 1, José CALASANS-MAIA2, José Mauro GRANJEIRO3,4, Mônica Diuana CALASANS-MAIA4 1- Graduate Program in Dentistry, Fluminense Federal University, Niteroi, RJ, Brazil. Wettability was estimated by measuring the equilibrium and hysteresis contact angles using the dynamic contact angle analysis, or Wilhelmy, technique.

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 studies by Samir E. Bishara had the highest volume of total citations with 7 articles among the first top-cited 100 articles. FRCs vary according to the type of fiber fillers and orientation of fibers, the latter being responsible. Epub 2009 Feb 10. Objective: To chemically characterize and evaluate the surface energy (SE) and composition of Y-TZP and Ti surfaces after different NTP application times. 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). The wettability of dentin surfaces conditioned with NVC-containing terpolymer was significantly higher (P<.05) (22 degrees, WA=73.77 erg/cm(2)) than dentin conditioned with GC dentin conditioner (29 degrees, W(A)=70.52 erg/cm(2)). Samples in groups 9 and 10 were prepared with grinding instruments. The values of the contact angle measurements indicated increased wettability for the HCP than the control cement.

Since then, many elastomeric impression materials have become available, as indicated on the following time line: Colloids. ABSTRACT:Aim: The aim of this bibliometric study was to analyze the most frequently cited article about shear bonding strength (SBS) in dentistry. when choosing a material with particular consideration for the significant volumes typically used. For this purpose oxidized silicon surfaces were methylated to different degrees. Resin-based materials with various monomers, used as restorative, Stable resin adhesion on Y-TZP and Titanium (Ti) surfaces has been problematic. When a lower fluence was used, the enamel surface roughness was higher, and vice versa. Axisymmetric drop-shape analysis and atomic force microscopy confirmed that the proposed surface treatments increased the nanometer roughness and/or the water contact angles. Ten disc-shaped specimens (12 × 1 mm) were mixed and fabricated at room temperature. The established materials for provisional restorations showed slightly lower levels of cell-viability but no significant cytotoxicity. – They are clean and do not have an unpleasant taste or smell. This in vitro study investigated the wettability of ten commercially available visible light-cured denture lining materials. 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). CHI promoted higher contact angles (p = .007) and EDC did not differ from the control group (p = .586). NTP decreased C and increased O on both surfaces independently of application protocol.
