AB  - Objective To determine color changes in bulk-fill composite and universal composite restorations with dissimilar dentin replacement materials in extracted teeth after staining in red wine. Materials and Methods Cylindrical, 4 mm deep, class I cavities were prepared in 140 human molars. Bottom 2 mm was restored with Biodentine (Septodont), everX posterior (GC) or experimental HAP inserts. Each dentin replacement material was covered with a 2-mm layer of a universal composite Filtek Z250 or Z550 (3M ESPE) or Gradia Posterior (GC). Groups combining top composite layer and the underlying dentin replacement were designated as "composite_dentin replacement." Filtek Bulk Fill (3M ESPE) and Tetric EvoCeram Bulk Fill (Ivoclar Vivadent) were placed as a single 4-mm layer. Color measurements were performed using Vita Easyshade 4.0 (Vita Zahnfabrik) initially and after 48-hours storage in red wine at 37 degrees C. Results Color differences (Delta E-oo) ranged between 2.1 +/- 0.7 (Z250_HAP) and 7.8 +/- 1.1 (Z550_everX). EverX resulted in higher Delta E-oo of the overlying composite than HAP (P  lt  .001) and Biodentine (P = .006). Generally, Delta E-oo was affected more by decreasing lightness (Delta L ') than changes in chroma (Delta C '). Conclusions EverX resulted in higher Delta E-oo of the restoration than Biodentine and experimental HAP after staining in red wine. No significant differences in Delta E-oo may be expected in different composites with the same underlying dentin replacement material. The same was generally true for bulk-fill and universal composites. Clinical Significance Similar extent of color changes may be expected in bulk-fill and universal composites. Highly translucent everX might exhibit greater color differences irrespective of the capping composite than non-translucent materials. Clinicians have a wider choice of composite materials to cover a particular dentin replacement material, for example, everX or Biodentine, as similar color differences may be expected in various overlying composite brands.

AB  - Objectives. To evaluate optical properties (color and translucency) of 'sandwich' restorations of resin-based composites and esthetically unfavorable dentin restoratives. Methods. Cylindrical 'dentin' specimens (8 mm in diameter and 2 mm thick, N = 5/group) were prepared using EverX Posterior (GC), Biodentine (Septodont), experimental hydroxyapatite (HAP) or conventional composites (Gradia Direct Posterior, GC; Filtek Z250 and Filtek Z500, 3M ESPE). Capping 'enamel' layers were prepared using composites (Gradia Direct Posterior, Filtek Z250 or Z550) of Al or A3 shade and the following thickness: 0.6, 1 or 2 mm. Color (Delta E) and translucency parameter (TP) were determined using a spectrophotometer (VITA Easyshade Advance 4.0, VITA Zahnfabrik). Data were statistically analyzed using analysis of variance with Tukey's post-hoc tests (alpha = 0.05). Results. TP was greatly affected by layer thickness, whilst Delta E depended on shade and layer thickness of the capping composite. HAP and Biodentine showed significantly lower TP and higher Delta E (deviation from 'ideal white') than composites (p  lt  0.05). Greater TP was seen in EverX_composite groups than in corresponding control groups of the same shade and thickness. TP of composites combined with Biodentine or HAP was below 2, lower than the corresponding control groups (p  lt  0.05). Within-group differences of Delta E were greatest in HAP_composite groups. EverX_Gradia and EverX_FiltekZ250 combinations showed the most comparable Delta E with the control groups. Significance. A 2 mm thick layer of composite covering dentin restoratives with unfavorable esthetics is recommended for a final 'sandwich' restoration that is esthetically comparable to a conventional, mono-composite control restoration.

AB  - High esthetic requirements present a challenge in restorative dentistry due to the complex structure of dental tissues, micromorphology and composition of dentin and enamel. Dental composite material is characterized by its excellent esthetic properties despite significant structural differences from the dental tissues. Nevertheless, optimum esthetic results are not easy to achieve and require balancing several clinical factors. The aim of this dissertation was to evaluate the effect of dentin restoratives with different optical properties than composite materials on the optical characteristics of the final restorations. This doctoral thesis investigates the optical characteristics (color and translucency) of such combined "sandwich" restorations related to their type, shade and thickness of the final composite layer. Fluorescence properties of materials, initial color and color stability and marginal integrity of combined restorations in prepared cavities in extracted teeth are also investigated in relation to the type of dentin restorative and final 'enamel' layer. Materials and Methods: The following materials were used as dentin restoratives: tricalcium-silicate cements (Biodentine, Septodont), experimental hydroxyapatite inserts (HAP), fiber-reinforced composite (EverX Posterior, GC). Filtek Z250 (micro-hybrid with Bis-GMA, 3M ESPE), Filtek Z550 (nano-hybrid, 3M ESPE), Gradia Direct (micro-hybrid without Bis-GMA, GC), of A1 or A3 shade, were used as control groups. For bulk-fill restorations nano-hybrid bulk-fill composite materials were used: Filtek Bulk Fill Posterior (3M ESPE) and Tetric EvoCeram Bulk Fill (Ivoclar Vivadent). Adhesives: Single Bond Universal (3M ESPE), Adhese Universal (Ivoclar Vivadent), GC G-aenial Bond (GC) were used with the respective composites. In the first part of the study, optical parameters of all materials, prepared in different layer thickness and shades were measured. Samples were made in standardized cylindrical plastic molds. Color (ΔE) and translucency (TP) were measured using a spectrophotometer VITA Easyshade® Advance 4.0 (VITA Zahnfabrik). The color, expressed as the deviation from ‘ideal white’, and translucency were determined according tothe CIEL*a*b* color system...

AB  - This study correlated the refractive indices (RIs) of unfilled resin mixtures and resin-based composites (RBCs) with color and translucency of conventional and low-shrinkage RBCs. Unfilled resin mixtures based on different ratios of conventional monomers Bisphenol A-glycidyl-methacrylate (BisGMA)/triethyleneglycol-dimethacrylate (TEGDMA) and urethane-dimethacrylate (UDMA)/TEGDMA and a low-shrinkage monomer FIT-852 (FIT, Esstech Inc.)/TEGDMA were used to prepare model RBCs, containing 30 wt % of the organic matrix and 70 wt % of silanated barium-glass fillers (n=1.553, Esstech Inc.). The RIs of resins were measured on an ABBE refractometer, those of cured RBCs using the Becke-line method in immersion oils. Color and translucency were determined using an AvaSpec-2048 (Avantes BV) spectrometer. The RIs of unfilled resin mixtures decreased with increasing amounts of TEGDMA. Cured RBCs had higher RIs than their respective resin mixtures. BisGMA-based composites were more translucent with significantly lower L* values than FIT- and UDMA-based RBCs. The RIs of unfilled resins positively correlated with cured RBCs (p=0.001), as did the RIs with translucency (p=0.001) and color (p=0.008). Resin mixtures and corresponding RBCs based on UDMA and its modified low-shrinkage version, FIT, showed similar optical properties. The RIs of unfilled resins appeared to be good predictors of the RIs of cured RBCs.
