“…36 The same study demonstrated that the solubility of RXU was comparable to, or lower, than the other investigated cements. Since water sorption is related to color stability of resin-based materials, 38 these findings are in accordance with the results of another recent study on the color stability of resin cements. 39 This group of authors found that the color stability of RXU was comparable to Panavia SA and lower than Panavia V5…”

ObjectivesCurrently, a classification of resin cements that includes relatively recently formulated (“universal”) cements is lacking. Furthermore, the terminology used to define different resin cements in the scientific reports is inconsistent. Accordingly, this work aims to: (i) propose a novel classification of resin composite cements; (ii) disambiguate the term “universal cements” and (iii) present an overview of the properties of these cements.MethodsAn analysis of peer‐reviewed literature (PubMed search), as well as market research on definitive resin composite cements were performed.ResultsA tendency toward simplified and versatile luting materials was observed both in the scientific literature and on the dental market with the advent of self‐adhesive/one‐step resin cements. However, additional priming procedures were necessary to improve their bonding performance in certain clinical situations. Hence, several cements that can be applied both in adhesive and self‐adhesive mode were introduced. These cements are associated with a universal adhesive resin, that can be used as a tooth and/or restorative material primer, without the need for other priming systems, regardless of the substrate. These systems should be considered truly universal. Therefore, we hereby suggested a new classification of resin‐based cements: (1) adhesive/multi‐step; (2) self‐adhesive/one‐step; (3) universal cements (one‐ or multi‐step). Despite promising in vitro results, clinical trials and long‐track laboratory studies are necessary to confirm the reliability of the universal cements.ConclusionsThis review presented the current advances in the field of resin‐based cements, which are reflected in the proposed classification. The term “universal cement” was disambiguated, which will help standardize the terminology used in published research.Clinical SignificanceThe classification of resin‐based cements and a better understanding of the proper terminology will help standardize the terminology in published research, as well as improve the understanding of the clinical practitioners of the different indications and possible modalities of use of the available cements.

“…9 These alterations promote a change in surface smoothness, loss of gloss, and color change because the surface roughness also interferes directly with the intensity and rate of pigmentation. 13 - 14 This is why it is imperative to assess the characteristics of these toothpastes and their effect on restorative materials.…”

“…Color stability is a crucial property of restorative materials, and color can be modified by intrinsic and extrinsic discolorations. 5 , 13 Intrinsic factors are associated with material degradation due to components such as organic matrix composition and the initiator system, whereas the size, content, and hardness of the filler particles are directly influenced by photopolymerization. 14 - 15 Extrinsic factors are associated with pigment adsorption and absorption derived from sources such as nicotine, medications, and the patient’s diet.…”

Characterization of whitening toothpastes and their effect on the physical properties of bulk-fill composites

Objective To characterize activated charcoal and 2% hydrogen peroxide-based toothpastes and investigate their effects on roughness, color change, and gloss of bulk-fill composite resin. Methodology Composite resin specimens (Aura Bulk Fill, SDI) were subjected to 5,000 brushing cycles with regular toothpaste (Colgate Total 12, [RT]), activated charcoal toothpaste (Bianco Dental Carbon, [AC]), or hydrogen peroxide-containing toothpaste (Colgate Luminous White Advanced, [HP]), with or without coffee exposure. The pH, particle characterization by scanning electron microscopy (SEM), and weight% of solid particles in the toothpaste were assessed. Roughness (Ra) was evaluated using a surface profile-measuring device, color change (∆E ab /∆E 00 ) by reflectance spectrophotometer, and gloss unit (GU) by glossmeter. Kruskal–Wallis, Dunn, Friedman, and Nemenyi tests were used, and the correlation coefficient test was performed between Ra and GU (α=0.05). Results RT presented a higher Ra after brushing and did not change after staining with coffee; moreover, the ∆E ab /∆E 00 values were higher for RT than HP. Regarding gloss, AC and HP obtained higher values compared to RT. A significant negative correlation between gloss and Ra was found for RT exposed to coffee. All toothpastes had a neutral pH; however, RT had the largest percentage of solids by weight. SEM images showed particles of many sizes: irregular shape (RT), more regular particles (AC), and spherical clusters (HP). Although surface roughness, color change, and gloss may compromise the longevity of restorations, the whitening toothpastes tested did not promote more morphology changes than regular toothpastes.
