Abstract Objectives The manufacture of dental crowns and bridges generates residual stresses within the veneering ceramic and framework during the cooling process. Residual stress is an important factor that control…
Abstract Objective This investigation was to generate (1) guidelines for designing a tensometer that satisfies the necessary accuracy and sensitivity requirements for measuring polymerization stress (PS), and (2) a formula…
Abstract Objectives To assess the influence of different temporary restorations and luting techniques of labside and chairside ceramic inlays on enamel defects and marginal integrity. Methods 120 extracted human third…
Abstract Objective Investigation of the replacement of bismuth oxide by zirconium oxide in mineral trioxide aggregate (MTA) and characterization and evaluation of the radiopacity and physical properties of varying replacements…
Abstract Objectives Microleakage testing of dental materials is a commonly accepted evaluation technique of margin integrity. Thermocycling has been utilized by many researchers to study the influence of temperature extremes…
Abstract Objective Many dental materials are used in contact with each other in sandwich techniques. Liners, bases and permanent restorative materials are placed adjacent to each other and allowed to…
Abstract Objectives This work is concerned with the study of the sorption and desorption process of water, ethanol or ethanol/water solution 50% (v/v) or 75% (v/v) by the dental resins…
Abstract Objective To assess by means of “thin-slice” push-out test, light and scanning electron microscopy, the interfacial strength and sealing ability of new self-adhesive resin cements when used to lute…
Abstract Objectives The aim of this study was to test whether the load bearing capacity of anterior zirconia crowns veneered with overpressed or layered, is similar and to evaluate the…
Abstract Objective To assess the influence of laser-textured surfaces on the adhesion of composite to dentin after being rotary prepared. Methods Thirty healthy teeth were kept in 0.1% thymol solution…
Abstract Objectives This retrospective clinical study evaluated the suitability of a glass ionomer system as a permanent restoration material in posterior cavities. Methods 26 Class I (1-surface (S1)) and 125…
Abstract Objectives The consumption of acidic soft drinks may lead to demineralization and softening of human dental enamel, known as dental erosion. The aims of this in vitro study were…
Abstract Objective To evaluate the influence of different surface treatments on the microtensile bond strength of resin cement to zirconia ceramic. Materials and methods Twelve cylinder-shaped ( 12 × 5.25…
Abstract Objective Test the hypothesis that glass-bonding of free-form veneer and core ceramic layers can produce robust interfaces, chemically durable and esthetic in appearance and, above all, resistant to delamination….
Abstract Objectives Polyacid-modified composite resins (compomers) are restorative dental materials that exhibit certain features of traditional dental composites and glass-ionomer cements. The aim of this paper was to develop experimental…
Abstract Objective. This study reports real time neutron diffraction on the Empress II glass-ceramic system. Methods . The commercial glass-ceramics was characterized by real time neutron diffraction, 31 P and…
Abstract Objective To use rapid scan FT-IR and Knoop microhardness to determine the effect of specimen temperature on the rate and extent of polymerization of a dental resin. Methods Two-millimeter…
Abstract Objective The objective of this study is to improve the performance of dental resins by adding a small amount of titanium dioxide nanoparticles (TiO 2 NPs), which have outstanding…
Abstract Objectives This study aims to assess the viability of using the acoustic emission (AE) measurement technique to detect and monitor in situ the interfacial debonding in resin composite restorations…
Abstract Objectives This retrospective longitudinal study investigated the longevity of posterior restorations placed in a single general practice using 2 different composites in filler characteristics and material properties: P-50 APC…
