“…CCBs showed color change beyond clinically acceptable thresholds in all studies except for one [ 15 ]. When compared with other materials, CCBs immersed in coffee solutions showed a significantly higher color change than lithium disilicate [ 13 , 15 , 19 , 28 , 35 , 36 , 37 ], zirconia-reinforced lithium silicate [ 15 , 22 ], hybrid ceramic [ 17 , 18 , 19 , 21 , 35 , 36 , 37 ], and feldspatic ceramic [ 13 , 26 , 37 ]. CCBs immersed in red wine showed a significantly higher color change than zirconia-reinforced lithium silicate [ 13 , 19 , 22 , 38 ], hybrid ceramic [ 14 ], and feldspatic ceramic [ 13 , 24 ].…”

“…A high risk of bias could be found in all RCTs except for one [ 36 ] regarding blinding, mostly owing to the fact that blinding of participants and personnel was not applied or declared. Randomization was clearly stated in only five investigations [ 15 , 19 , 27 , 28 , 36 ]. Eleven studies reported complete information regarding sample size calculations [ 12 , 14 , 16 , 19 , 24 , 25 , 26 , 28 , 36 , 37 , 38 ], eight regarding sampling technique [ 12 , 15 , 16 , 25 , 27 , 28 , 37 , 38 ], and two regarding the comparison (control) group [ 28 , 36 ].…”

“…CAD/CAM composite blocks [ 12 ] (CCB) (also referred as resin nano-ceramic [ 13 , 14 , 15 , 16 , 17 , 18 , 19 ], resin ceramic [ 20 ], resin-based composites blocks [ 21 , 22 , 23 , 24 ], nanohybrid restorative materials [ 25 ], nano-hybrid ceramic [ 26 ], hybrid composites [ 27 ], hybrid ceramic [ 28 ]) have recently gained popularity as they are considered to offer a higher quality compared to composite used in a conventional manual procedure in both direct and indirect restorations. This is mainly due to the standardized industrial production processes, for which high temperature and/or high-pressure polymerization are used.…”

Color Stability of Polymer-Based Composite CAD/CAM Blocks: A Systematic Review

et al. 2023

View full text Add to dashboard Cite

Background: This systematic review aims to evaluate the color stability of resin composite CAD/CAM blocks (CCB) when submitted to staining solutions. Methods: A systematic search was performed on different databases (Embase, Medline, Scopus, Web of Science). Search terms were: ‘polymer infiltrated’, ‘polymer-based’, ‘resin nanoceramic’, ‘resin ceramic’, ‘hybrid composite’, ‘hybrid ceramic’, ‘composite ceramic’, ‘resin infiltrated’, ‘CAD-CAM’, ‘CAD/CAM’, ‘color stability’, ‘staining’, ‘staining susceptibility’, ‘color change’, ‘color difference’. Inclusion criteria: in vitro articles published in the English language until 18 September 2022 without initial time restriction evaluating the color stability of CCB when submitted to staining solutions. Exclusion criteria: studies investigating color change induced by smoke or whitening treatments; studies not including a clinical evaluation of the results using the thresholds for color perceptibility and acceptability. Risk of bias assessment using the QUIN tool. Findings: Out of the 378 initially retrieved articles, 19 were included in this review. They investigated 17 different CCBs and different artificial staining by liquid protocols, including coffee, red wine, tea, and cola. CCBs exceeded clinical acceptability thresholds for color shift in 18 out of 19 studies, with a significantly higher color stability than conventional hybrid resin-based composites (RBCs), and a significantly lower color stability than ceramic materials. The identified differences in CCBs in color stability can be attributed to the material’s composition, but also to the heterogeneity of staining procedures. Interpretation and clinical implication: Clinicians should be aware that, although to a lower degree when compared to RBCs used in direct or indirect procedures, CCBs undergo color changes to a higher degree in comparison to ceramic materials.

“…The organic structure and filler particle properties of resin composites also have a direct effect on the surface roughness of the restoration and the tendency to external coloring [ 14 ]. Commonly consumed beverages, including tea, coffee, red wine, fruit juice, and cola have been reported to cause significant discoloration in resin composites [ 15 ].…”

The effect of bleaching applications on stained bulk-fill resin composites

2022

Background The structure of bulk-fill resin composites differs from that of their conventional counterparts, but how this difference affects the color stability of the former after staining and bleaching is unclear. Accordingly, this study was aimed at investigating color change in nine bulk-fill resin composites and one nanohybrid resin composite treated with hydrogen peroxide and carbamide peroxide after staining with tea, coffee, and red wine. Methods Eighty specimens were prepared from each resins [Clearfil Majesty Posterior (CMP), SDR flow+ (SDR), FiltekTMBulk-Fill Flowable Restorative (FBF), Reveal HD Bulk (RHD), Beautifil-Bulk Restorative (BBR), Tetric EvoCeram® Bulk Fill (TEC), SonicFill™2 (SF2), everX Posterior™ (eXP), X-tra base (XB), and Venus® Bulk Fill (VBF)]. Following baseline color measurements, the specimens were randomly divided into 4 groups according to immersion solutions and distilled water as the control. At the end of a 30-day test period, color measurements were repeated, and color change values (∆E00) were calculated. Each resin group was then divided into 2 subgroups (with 10 specimens per group) on the basis of bleaching agent (Opalescence Boost 40%, Opalescence PF 16%). Following bleaching application, ∆E00 and changes of whiteness (∆WID1 = WIDbleaching-WIDbaseline, ΔWID2 = WIDbleaching-WIDstaining) values were recorded. Two- and three-way analyses of variance and Tukey’s post hoc test were performed, with a P < 0.05 regarded as indicative of significance. Results After immersion in distilled water, tea, and red wine, the highest ΔE00 values were observed in eXP (P < 0.05). Resin materials immersed in coffee and tea exhibited statistically higher ∆E00 values than those immersed in red wine except for eXP, TEC, and FBF (P < 0.05). For eXP, the highest ∆E00 values were recorded in distilled water. For TEC and FBF, there was no statistically significant difference among the immersion solutions and distilled water (P > 0.05). For all the resins and staining beverages, no statistically significant difference in ∆WID1 and ∆WID2 values were detected between bleaching agents (P > 0.05). All the ΔWID1 values were above the whiteness perceptibility threshold. Conclusion The bulk-fill materials were more resistant to discoloration and bleaching procedures than the conventional resin composites. Coffee and tea caused more staining than distilled water and red wine generally. The type of bleaching procedure had no effect on the whiteness of the tested materials.
