This study evaluated the effect of structural color phenomenon in resin composites (RCs) on adjustment restorations by investgating their reproduction performance human incisors various shade. Cervical cavities were filled with a single-shade RC 260 nm spherical fillers (Omnichroma (OMN)), conventional A2-shade RCs (Estelite Σ Quick or Clearfil AP-X), experimental 5–50 fumed silica (R1) and 100 (R2). Color parameters (L*C*h*) measured using CIE XYZ camera along centerline restorations,...
Higher 24-hour resin-dentin bond strengths are created when ethanol is used to replace water during wet bonding. This in vitro study examined if ethanol-wet-bonding can increase the durability of bonds over longer times. Five increasingly hydrophilic experimental resin blends were bonded acid-etched dentin saturated with or ethanol. Following composite build-ups, teeth reduced into beams for microtensile strength evaluation, and water-aging at 37°C 3, 6, 12 months before additional...
Zirconia ceramics have been widely used as dental restorations due to their esthetic appearance and high flexural strength. The bonding of zirconia with resin cement should rely on both mechanical chemical bonds. This study was performed investigate the effect surface topography its wettability after pretreatments microshear bond strength (μSBS) a cement. slabs were prepared randomly divided into 5 groups based treatment follows: no (control), air abrasion (AB), etching hydrofluoric acid...
The recently introduced resin composites with a universal shade are claimed to match any tooth color. In this study, it was examined how composite thickness affects the color adjustment of conventional and universal-shade background dentin. Thirty sound human central incisors various were used, differences between their intact labial surfaces, exposed dentin surfaces restorations (thickness 1-3 mm) evaluated. addition, translucency, light transmission characteristics, spectral reflectance...
The degree of conversion contemporary universal adhesives positively correlates with the bond strength to dentin. correlation is more marked after thermocycling, suggesting that a high required for long-term dentin bonding durability.Purpose: objectives this study were evaluate micro-tensile (μTBS) five 24 hours and thermocycling (TC), measure their degrees (DC) test between μTBS DC.Methods Materials: Four commercially available adhesives, Prime&Bond (PBU), Ecosite Bond (EB), G-Premio (GPB),...
The effect of curing mode dual-cure resin cements on the tensile bond strength (TBS) universal adhesives to enamel, dentin, zirconia, lithium disilicate ceramics (LDS), feldspathic porcelain (FP), and a Pd-Au alloy was evaluated. substrates were bonded using Tokuyama Universal Bond (TUB) or Scotchbond Adhesive (SBU), followed by luting with Estecem II (ECII) Rely-X Ultimate (RXU), respectively, which used either in light-curing self-curing mode. TBS test performed after 24 h 5,000 thermal...
Few studies have reported on the impact of oxidative stress dental implant failure. The aim this study was to investigate hyperglycemia-induced osseointegration in diabetes mellitus (DM).Acid-treated titanium implants were bilaterally placed maxillary alveolar ridge streptozotocin-induced diabetic (DM group) and control rats after extraction first molars. Histological analysis micro-push-out test performed 4 weeks surgery. Oxidative osteogenic markers surrounding bone quantified by real-time...
The color-matching ability of single-shade composites Omnichroma (OMN) and Flow (OCF) is ensured by structural color, which arises from monodisperse 260 nm spherical fillers. This study evaluated how filler load influences the color adjustment potential composite restorations to human teeth various shades. performance containing fillers —OMN (79 wt%), OCF (71 experimental R1 (65 R2 (60 wt%)— was compared two conventional A2-shade a transparent composite. Additionally, translucency parameter,...
Patients: This case report presents a minimally invasive approach to replace missing mandibular lateral incisor using dual-injection molding technique with flowable composite resins. Integrated comprehensive digital workflow, this method achieves structurally and esthetically biomimetic, bi-layered prosthetic solution. A 34-year-old woman congenital absence of was successfully rehabilitated direct resin-bonded fixed partial denture (RBFPD).
