The solutions formulated with concentrations ranging from 0.125 to 0.

Influence of N-(2-hydroxyethyl)acrylamide addition in light- and dual-cured resin cements.

Objective: To develop experimental light-cured (L) and dual-cured (D) resin cements containing N-(2-hydroxyethyl)acrylamide and evaluate the physicochemical and optical properties.

Methods: Experimental resin cements were formulated using bisphenol A-glycidyl dimethacrylate (70%) and 2-hydroxyethyl methacrylate (30%), in the control groups, and, bisphenol A-glycidyl dimethacrylate (70%) and N-(2-hydroxyethyl)acrylamide (30%). Polymerization kinetics were evaluated by differential scanning calorimetry (n = 3), softening in solvent (ΔKHN) evaluated by the difference of Knoop microhardness before (KHN) and after (KHN) ethanol solution immersion (n = 5), radiopacity in mmAl (n = 5), film thickness (n = 3) and color stability were evaluated.

CAD/CAM or conventional ceramic materials restorations longevity: a systematic review and meta-analysis.

Purpose: This systematic review and meta-analysis aimed to evaluate the difference in longevity of tooth-supported ceramic prostheses designed by conventional and computer-aided design/computer-aided manufacturing (CAD/CAM) techniques.

Study Selection: Two reviewers searched the Web of Science, PubMed, SCOPUS and LILACS databases between 1966 and October 2017. Clinical studies that compared the survival rate of CAD/CAM against conventional restorations were included.

Impact of shelf-life simulation on bonding performance of universal adhesive systems.

Objectives: To evaluate the micro-tensile bond strength to dentin (μTBS), the degree of conversion (DC) and nanoleakage expression (NL) of eight dental adhesives considering their expiry date (as-received, half-life and or end of shelf-life) after shelf-life simulation.

Methods: Five universal adhesives (Single Bond Universal, SBU; Tetric Bond Universal, TBU; OneCoat Universal, OCU; OptiBond Universal, OBU; and Prime&Bond Elect, P&B), two two-step self-etch adhesives (Clearfil SE, CSE; and AdheSE, ASE) and one two-step etch-and-rinse adhesive (Adper Singlebond 2, ASB) were evaluated. Shelf-life was simulated by storing the materials in an acclimatization chamber for different periods of time.

Quaternary ammonium compound as antimicrobial agent in resin-based sealants.

Objectives: The aim of this study was to evaluate the influence of [2-(methacryloyloxy)ethyl] trimethylammonium chloride (METAC) in the physico-chemical properties, antibacterial activity and cytotoxicity of an experimental resin-based sealant.

Materials And Methods: An experimental resin-based sealant was formulated with dimethacrylates and a photoinitiator system. METAC was added at 2.

Antibacterial, chemical and physical properties of sealants with polyhexamethylene guanidine hydrochloride.

The aim of this study was to evaluate the influence of polyhexamethylene guanidine hydrochloride (PHMGH) in the physico-chemical properties and antibacterial activity of an experimental resin sealant. An experimental resin sealant was formulated with 60 wt.% of bisphenol A glycol dimethacrylate and 40 wt.

Acrylamides and methacrylamides as alternative monomers for dental adhesives.

Objective: Synthesize and characterize a methacrylamide monomer for adhesive system and evaluate the physicochemical properties of the adhesive resin.

Methods: The liquid methacrylamide monomer N,N',N″-(nitrilotris(ethane-2,1-dyil)tris(2-methylacrylamide) (TMA) was prepared by reaction of methacrylic anhydride and tris(2-aminoethyl)amine with 60% yields. The TMA structure was analyzed by H NMR, C NMR, ATR-FTIR and UHPLC-QTOF-MS.

One-year aging effects on microtensile bond strengths of composite and repairs with different surface treatments.

The present study aimed to evaluate effects of different surface treatments and aging of composite cylinders on bond strength of composite resin repair. Thirty-two composite cylinders were produced and divided into four groups according to type of surface treatment and storage time of composite cylinder and repair. Cylinder surface of control group (Gcontrol) received no treatment before composite repair.

Influence of hydroxyethyl acrylamide addition to dental adhesive resin.

Objective: to determine the physicochemical properties of experimental adhesive resins containing hydroxyethyl acrylamide.

Methods: Three groups of experimental resin were formulated, GHEAA33% (33.3wt% HEAA+66.

Chlorhexidine application in adhesive procedures: a meta-regression analysis.

Purpose: To evaluate the association between chlorhexidine application and the bond strength of an adhesive system to dentin and to assess the association among eight other variables.

Materials And Methods: Laboratory studies evaluating the use of chlorhexidine on dentin that verified the immediate and longitudinal bond strength were included. The terms were selected according to the Medical Subject Headings (MeSH) for PubMed and adapted for the other databases accordingly.

Influence of delayed pouring on irreversible hydrocolloid properties.

The aim of this study was to evaluate the physical properties of irreversible hydrocolloid materials poured immediately and after different storage periods. Four alginates were tested: Color Change (Cavex); Hydrogum (Zhermack); Hydrogum 5 (Zhermack); and Hydro Print Premium (Coltene). Their physical properties, including the recovery from deformation (n = 3), compressive strength (n = 3), and detail reproduction and gypsum compatibility (n = 3), were analyzed according to ANSI/ADA specification no.
