Color and translucency stability of contemporary resin‐based restorative materials

Abstract

Objective To determine color and translucency stability of present‐day resin‐based restorative materials. Materials and methods Disk‐shaped (1.0 × 10 mm) resin composites (Filtek Universal, 3M ESPE; Spectra ST, Dentsply Sirona; Gradia Direct X, GC America; Estilite Quick, Tokuyama; Harmonize, Kerr; ACTIVA Bioactive‐Restorative, Pulpdent) were prepared and divided into four staining groups (n = 5); coffee (55°C), grape juice (5°C), deionized water (25°C) and thermocycling (20 000 cycles, 5°C to 55°C with a 30‐second dwell time). Spectrophotometer measurements were taken at baseline and 14 days for each group and the color stability (CIEDE2000) and changes in the translucency parameter (RTPCIEDE2000) and luminous transmittance of each composite were determined. A 2‐way analysis of variance (ANOVA) using maximum likelihood estimations was used for analysis for these changes, with subsequent pairwise comparisons using Bonferroni‐corrected Student's t tests and an experiment‐wise α = 0.05. Results A significant interaction (P < .0001) between material and treatment was found for each change in the esthetic property tested over 14 days. Multiple significant differences between materials for each treatment and between treatments for each material were identified. Conclusions The severity of color change and translucency of resin‐based materials are dependent on their type, mostly affected by the coffee staining medium. Nano‐filled resin composite is most resistant to color change and with stable translucency after artificial aging. Clinical Relevance Nano‐filled resin composite may be the most esthetically durable resin‐ based restorative material. Micro‐hybrid resin composite and resin‐modified glass ionomer restorative material are susceptible to color change and losing their translucency. Hot coffee solution may shorten the esthetic lifespan of a resin‐based material.

Color Stability of Orthodontic Ceramic Brackets and Adhesives in Potentially Staining Beverages—In Vitro Study

“…This is in correlation with previous studies which confirm that coffee has the highest staining potential [5,13,23]. Moreover, adhesive samples showed the same results in our and other studies [18,26]. According to the literature, coffee might produce more remarkable color changes of the material in comparison to other solutions (e.g., Coca-Cola) even though these solutions have similar color parameters [17].…”

“…159 However, it has been reported that the color stability of a few of the current universal composite resins is not ideal. 161 Another characteristic of a few universal composite resins is the exclusion of Bis-GMA from the respective organic matrix. Since the introduction of the first composite resin, the composition of the organic matrix of composite resins has not changed considerably.…”

Color and Translucency Stability of Three-Dimensional Printable Dental Materials for Crown and Bridge Restorations

“…While there have been several studies of the color and translucency of dental resin-based composites (RBCs) for direct restoration as well as indirect dental ceramic materials [ 15 , 16 , 17 , 18 , 19 ], only limited information is available about those of 3D printable dental materials. Revilla-León et al measured the color of 3D printable dental materials and compared them with those of conventional acrylic resin-based interim materials [ 20 ].…”
