“…The results described in the current study concur with those obtained by Gurgan et al [ 27 ] for the color stability of Filtek Universal and G-ænial A´chord. Those authors also found that G-ænial A´chord presented excellent optical properties, which are features supported by the improved polishing properties of these nano-hybrid composite resins [ 27 ].…”

Objectives This study compared the surface gloss (SG), gloss retention (GR), and color stability (CS) of 2 universal resin composites after chemical (CA) and mechanical (MA) aging. Materials and Methods Twenty disc-shaped samples of G-ænial A´Chord (GC-Europe) and Filtek Universal (3M-ESPE) were polished with sequential abrasive papers. For CA, specimens were stored in 1 mL of 75% ethanol for 15 days at 37°C, and readings (SG, GR, and CS) were obtained at baseline and 5, 10, and 15 days. For MA, specimens were subjected to 10,750 simulated brushing cycles. SG and CS were evaluated after every 3,583 cycles. SG was measured with a glossmeter (geometrical configuration: 60°), and values were expressed in gloss units. Color was measured with a spectrophotometer using the CIE-L*a*b* color system. The Student’s t -test, 1-way analysis of variance, and Scheffé test were used for statistical analysis (α = 0.05). Results G-ænial presented significantly higher SG values than Filtek ( p = 0.02), with GR reductions of 5.2% (CA) and 5.3% (MA) for G-ænial and 7.6% (CA) and 7.2% (MA) for Filtek. The aging protocol had no statistically significant effect on SG or GR ( p = 0.25) from baseline to the final readings. G-ænial–MA presented the lowest color difference (∆E = 1.8), and G-ænial–CA and Filtek–CA had the largest changes ( ∆E = 8.6 and ∆E = 11.8, respectively). Conclusion G-ænial presented higher SG values and better CS. Both restorative materials demonstrated acceptable GR and CS. Aging protocols impacted these properties negatively.

Tests of Dental Properties of Composite Materials Containing Nanohybrid Filler

et al. 2022

Complex composite materials are used in many areas of dentistry. Initially, chemically hardened materials were also used, and in this group nanohybrid composites are highly valued. They are often used today, mainly for the direct reconstruction of damaged hard tooth tissue materials for rebuilding damaged tissues using indirect adhesive techniques. The research was conducted to determine the mechanical properties of materials with nanofillers. The article focuses on methods of important test methods for dental prosthetics: resilience, abrasion, wear test, impact strength, hardness, SEM, and chemical analysis. As part of this work, five different series of hybrid composites with nano-fillers were tested. The mechanical properties of composites, such as compressive strength, microhardness, flexural strength, and modulus of elasticity, depend mainly on the type, particle size, and amount of filler introduced. The obtained test results showed that the type and amount of nanofiller have a significant influence on the mechanical and tribological properties. The introduction of nanofillers allowed us to obtain higher mechanical properties compared to classic materials discussed by other researchers. The study observed a change in vibrations in the IR spectrum, which allowed a comparison of the organic structures of the studied preparations.

“…However, the improvements in esthetic materials and techniques have facilitated the road to esthetic restorations, in terms of simplifying the shade selection. 1,8 Accordingly, it is the level of optical determinants as well as the filler technology and contents that generates the esthetic qualification of the final restoration. [7][8][9][10] Proper material and shade selection, and appropriate layering protocol should be determined to obtain an optimal esthetic result.…”

Objectives The aim of this retrospective evaluation was to assess the short‐term outcome of two monoshade universal resin composites with high chameleon effect in anterior direct veneer and diastema closure restorations, and to investigate the possible reasons for failure. Material and Methods Patients subjected to veneer and diastema closure restorations with two monoshade universal resin composites (Essentia Universal Shade; EU, GC Corp., and Omnichroma; OC, Tokuyama) operated between January 2018 and March 2019 were selected for the present retrospective evaluation. A total of 159 composite restorations (78 veneers and 81 diastema closure restorations) performed by a single operator in 44 patients (mean age: 33.6) were included in the study. Two blinded and calibrated examiners performed 1‐ and 2‐year assessments of the restorations with respect to FDI criteria, using medical/clinical history and dental photography records. Data were analyzed using Pearson Chi‐square with Continuity Correction, Fisher's Exact tests, and Cox regression (a < 0.05). Results The cumulative overall survival rates of EU and OC restorations were 94.6% (97.3% for the first year) and 88.6% (95.3% for the first year), respectively, with no significant difference from each other (p = 0.316). The cumulative overall survival rates of direct veneer and diastema closure restoration types were 90.2% (95.1% for the first year) and 92.4% (97.4% for the first year), respectively, with no significant difference (p = 0.559). The reasons for failure were evaluated as fracture of the restoration, failure in esthetic anatomical form, and color mismatch. All the failed direct veneer restorations were due to fractures (FDI score of 5.4), whereas 5 of 6 failed diastema closure restorations were due to color mismatch (FDI score of 3.4). Regarding the composite materials, there were no significant differences between the success rates of the restoration types (p = 0.442 for EU, p = 1.000 for OC). With respect to the restoration types, there were also no significant differences between the success rates of the resin‐based composites (p = 1.000 for direct veneer restorations and p = 0.228 for the diastema closure restorations). In addition, no significant difference was observed between male and female patients regarding the acceptable and unacceptable scores (p = 1.000). Conclusions The 2‐year clinical performance of the two monoshade universal composites in anterior veneer and diastema closure restorations were both considered successful and similar. Despite the lack of shade selection, both monoshade universal composites presented a successful color match. However, the diastema closure restorations might be more prone to color mismatch compared to the veneers over time, while veneer restorations presented more fractures than the diastema closure restorations. Clinical Significance Monoshade universal composites presented successful short‐term clinical outcomes regarding both function and esthetics in anterior direct veneer and diastema closure r...
