The aim of this in vitro study is to compare the color stability and surface roughness conventional self-blending resin composites before after staining aging. Three (Filtek Z350, IPS Empress Direct, Estalite Palfique LX5) one (Omnichroma) composite were used study. Sixty discs prepared polymerized a metal mold (n = 15 per group). Samples then finished polished by Layan discs. Color testing measured as baseline (T0) spectrophotometer profilometry. stained with tea for 24 h, water aged 30...
Contamination of zirconia restorations before cementation can impair the resin-zirconia bonding durability. The objective this study was to evaluate effect human saliva or blood decontamination with 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP)-containing cleaner on shear bond strength (SBS). A total 220 specimens were prepared and air-abraded randomly distributed into 11 groups (n = 20 per group). Except for control group (no contamination), contaminated either (five groups)...
BACKGROUND This in vitro study aimed to compare the color stability and effect of polishing on single-shade conventional resin-based composite after immersion commonly consumed beverages over certain time intervals. MATERIAL AND METHODS We prepared 120-disc specimens using 2 universal resins (n=30) then each group was divided into 3 groups solutions (n=10/solution): distilled water, coffee, cola. To mimick clinical situation, with Soflex system performed. Color measurement recorded for every...
Novel dentin bonding pretreatment using copper sulfate (CuSO4) and dipotassium hydrogen phosphate (K2HPO4) may create a more hydrophobic environment for bonding. Thus, this study aims to investigate the impact of CuSO4 + K2HPO4 on μTBS when bonded with universal adhesive conventional CAD/CAM resin composites. Eighty recently extracted human molars (n = 80) were chosen placed in transparent acrylic blocks expose crowns entirely. Nano-filled composite selected. Based pretreatment, type...
(1) Background: A newer class of flowable bulk-fill resin-based composite (BF–RBC) materials requires no capping layer (Palfique Bulk flow, PaBF, Tokuyama Dental, Tokyo, Japan). The objective this study was to assess the flexural strength, microhardness, surface roughness, and color stability PaBF compared two BF-RBCs with different consistencies. (2) Methods: SDR Flow (SDRf: Charlotte, NC, USA) One fill (OneBF: 3M, St. Paul, MN, were evaluated for strength a universal testing machine,...
Background: Silane-containing universal adhesives (UAs) are marketed as adhesion promotors for glass-ceramics. Objectives: This study aimed to evaluate the priming capacity of γ-methacryloxypropyltrimethoxysilane (γMPTS)-containing and γ-methacryloxypropyltriethoxysilane (γMPTES)/3-(aminopropyl)triethoxysilane (APTES)-containing lithium disilicate ceramic (LDC). Materials Methods: Etched LDC discs were distributed into four groups according material used: (control), no priming; (MBN), was...
Cention N (CN; Ivoclar Vivadent, Schaan, Liechtenstein), advertised as an alkasite, is a bioactive bulk-fill resin-based composite (BF-RBC) with alkaline fillers. This study evaluated the resin-dentin micro-tensile bond strength (μTBS) and cytotoxicity of CN. Methods: Flat dentin surfaces were obtained, bonded universal adhesive, randomly distributed into two groups. CN (group I) flowable BF-RBC, namely, Tetric N-Flow Bulk Fill, Liechtenstein II), used. After thermocycling, samples sectioned...
This study evaluated the effect of 2% inositol hexaphosphate (IP6) and 10% polyacrylic acid (PAA) on dentin surface micromorphology, matrix/mineral ratio, microhardness, resin−dentin shear bond strength (SBS) a self-adhesive restorative material (Surefil™ One; Dentsply Sirona, Konstanz, Germany). Human permanent molar mid-coronal discs were either not treated (control), conditioned with PAA (Dentin Conditioner, GC, Tokyo, Japan) for 20 s, or etched IP6 s. Dentin micromorphology (etching...
To evaluate the effects of surface treatment and repair material on shear bond strength (SBS) bioactive restorative material.A total 240 Activa BioActive Restorative (Activa) discs were prepared, aged, polished, divided randomly into eight groups (n = 30). Groups 1-4 repaired with bulk-fill flowable resin-based composite (Bulk-RBC), 5-8 Activa. Surface used for each type air abrasion silica-coated 30-m Al2O3 particles (air abrasion) (Groups 2 & 6), Air universal primer 3 7), adhesive 4 8). 1...
Dental practitioner-related factors can affect the quality of composite restorations. This study aimed to investigate clinical techniques used by dental practitioners (DPs) while placing direct posterior restorations.A questionnaire survey that sought information related placement restorations was delivered 161 DPs working in Al-Kharj area, Saudi Arabia. The collected data were statistically analyzed using Pearson's Chi-square test and Fisher's exact considering DP's sector answered...
Abstract Objective This article evaluates the etching efficacy of a self-etching ceramic primer (SECP) on zirconia-reinforced lithium silicate (ZLS) ceramics. Materials and Methods Celtra Duo (DeguDent GmbH, Hanau-Wolfgang, Germany) Vita Suprinity (Vita Zahnfabrik, Bad Säckingen, were used in this study. A total 36 slices prepared from each material randomly distributed into three groups according to surface treatment applied (n = 12 per group). Group 1 (polished) was polished with silicon...
Objective: The objective of this study was to evaluate the resin-ceramic adhesion a long-carbon-chain silane (LCSI)-containing resin cement. Methods: Polished lithium disilicate ceramic discs were etched with hydrofluoric acid and randomly assigned into four groups; (PSAP), cemented using silane-free cement no prior priming; (PSAP-S), primed silane-containing primer before cementation cement; (PSAU), LCSI-containing (PSAU-S), as for group (PSAP-S) blocks sectioned microbeams. microtensile...
