Abstract Purpose To investigate and compare the translucency color stability of a newly introduced polymer‐infiltrated ceramic network (PICN) material (Crystal Ultra) to those clinically well‐established restorative materials. Materials Methods A total 80 specimens measuring (12 × 14 1 mm ± 0.05 mm) were prepared from five CAD/CAM (IPS e.max (IPS), Lava Ultimate (LU), Cerasmart (CS), Vita Enamic (VE), Crystal Ultra (CU)) high (HT) blocks in A2 or equivalent shades. Specimens randomly...
Various 3D printing systems for interim fixed dental restorations are commercially available. This study aimed to evaluate the physical and mechanical properties of printed resins used fabricated using various angulations after accelerated aging. Three different restorative materials were provided their specific (A: NextDent; B: Asiga; C: Nova3D), testing specimens from each system at two building angles: (1) 0° (2) 90°. The six groups A1, A2, B1, B2, C1, C2, with sixteen per group. Half in...
The influence of different thicknesses, translucencies, and fabrication methods on the spectrophotometric topographical properties zirconia-reinforced lithium silicate glass-ceramics (ZLSs) for dental restorations remains unclear.
Polymer 3D printing has is used in a wide range of applications the medical field. Polyamide 12 (PA12) versatile synthetic polymer that been to reconstruct bony defects. Coating its surface with calcium phosphate compounds, such as hydroxyapatite (HA), could enhance bonding bone. The aim this study was coat 3D-printed polyamide specimens by simple innovative treatment using light-cured resin cement. powder printed selective laser sintering produce 80 disc-shaped (15 mm diameter × 1.5...
Background: One of the crucial factors influencing longevity anterior aesthetic dental restorations is colour stability resin composites. Bleaching and whitening have become popular methods for enhancing aesthetics. Home techniques, such as special pens, are widely available commercially. This in vitro study aimed to determine efficiency a pen removing tea stains from composite by measuring differences (ΔE00). Additionally, evaluate variations parameters measured extra-oral intra-oral...
The aim of this study was to compare the surface roughness and gloss polymer-infiltrated ceramics after simulated in vitro toothbrushing different storage mediums. Four polymer- infiltrated were evaluated, Lava ultimate (LU), Vita enamic (EN), Shofu (SH), Crystal ultra (CU). control group a feldspathic ceramic, Mark II (VM). One hundred twenty specimens (12 × 14 2.5 mm) prepared using precision saw. For each material (n = 24), allocated into two groups, polished stained. stored (for 7 days)...
Purpose The study compared the color change, lightness, and translucency of hybrid resin ceramics exposed to toothbrush abrasion surface treatment. Materials methods Four [Lava Ultimate (LU), Vita Enamic (EN), Shofu HC (SH), Crystal Ultra (CU)] were with a glass-ceramic (Vita Mark II) control. One hundred twenty specimen blocks prepared using precision saw machine. Specimens in each material divided into four subgroups based on treatment (polishing or staining) storage medium (water citric...
Degradation of the collagen fibrils at dentin-resin interface by enzymatic activity matrix metalloproteinases (MMPs) has been known to permit some dental restoration complications, such as microleakage, secondary caries, and, ultimately, failures. This study aimed evaluate a modified adhesive adding an MMP inhibitor from green tea extract with and without nanotube encapsulation sustain drug release. Epigallocatechin-3-gallate (EGCG) Halloysite nanotubes (HNTs) were prepared produce three...
The objective of this study was targeted to synthesize and characterize a carbon nanotubes (CNTs) incorporated poly(methyl methacrylate) (PMMA)-based denture polymer. Two experimental base polymers were fabricated either by incorporating single-walled CNTs (SWCNTs) (SW-group) or multi-walled (MWCNTs) (MW-group). In both groups, 0.5 wt% the into MMA monomer. Using commercially available heat-cured PMMA (Interacryl Hot, Interdent, Opekarniska, Slovenia), polymer-to-monomer ratio 3:1 used...
This laboratory study was assessing the nano-mechanical properties (NMP), surface roughness (Sa), and topographic changes caused by ethanol on of heat-polymerized denture base polymers at different time past dough stage. Specimens heat polymerizing acrylic resin (Interacryl Hot, Interdent, Celje, Slovenia) size 10×10×3 mm were prepared, wet ground, polished for uniform smoothness treated with in concentrations 40, 70, 99.9% 30, 60, 120 s statistical analysis done. Some significance Sa...
Adhesive resin composite, which is used to bond orthodontic bracket tooth surface exposed the influence of wear by brushing and may loosening bracket.The aim this study was evaluate in vitro effect on adhesion strength brackets bonded treated porcelain.A total 90 glazed porcelain fused metal facets (PFM) were randomly assigned into 3 groups according treatment be received. Group 1 conditioned with hydrofluoric acid (HF), group 2 grit-blasting (GB) tribochemical silica coating (RC). The...
Matrix metalloproteinase (MMP)-induced collagen degradation at the resin-dentin interface remains a significant challenge for maintaining longevity of dental restorations. This study investigated effects epigallocatechin-3-gallate (EGCG), potent MMP inhibitor, on adhesive curing efficiency when encapsulated in halloysite nanotubes (HNTs). EGCG-loaded HNTs were incorporated into commercial (Adper Scotchbond Multi-Purpose) 7.5% and 15% w/v concentrations. To isolate each component, included...
To evaluate and compare the effect of accelerated aging coffee immersion on microhardness gloss a new CAD/CAM hybrid material (Crystal Ultra) to those contemporary restorative materials.A total 160 specimens (12 x 14 1 mm ± 0.05 mm) were obtained from (IPS e.max [IPS], VITA Enamic [VE], Crystal Ultra [CU], Lava Ultimate [LU], CeraSmart [CS]) high-translucency blocks. The Vickers determined following thermocycling immersion. Data analysis was performed using SPSS (α = .05).IPS CS exhibited...
This in vitro study compared the color change (∆E) and biaxial flexural strength (BFS) of two resin nanoceramics (LU CS) polymer-infiltrated ceramic networks (VE CU) after different surface finishing protocols. A total 192 discs (12 × 1.2 mm2) were prepared from materials (n = 48) then polished with 1200-grit silicon carbide paper, followed by roughening a 30 µm grit diamond bur. According to applied, each material category categorized into four groups: control group (no finishing),...
