“…An inadvertent contact of the highly concentrated bleaching material with the soft tissues of the oral cavity could induce increased levels of MN in the oral epithelial cells, as oxygen free radicals released from peroxides are important etiologic agents in the development of many pathological conditions. [50][51][52] This reinforces the need for caution during in-office bleaching, 50 as under controlled in-office conditions, such as those of the present study, this is not expected to occur.…”

“…Nevertheless, the softening potential of a beverage is related to the compositional variations of the materials regarding the nature of the resin matrix and hydrophilicity, cross-linking density and the porosity of the network, the nature of the filler system, and the quality of the matrix/filler interface as well as the photoinitiators. 30,44,51,52 Furthermore, after light curing, dark polymerization, unpolymerized monomer conversion, and/or additional crosslinking reactions continue up to one week. 30,51,53 All of these factors vary between materials and influence the final respective material and specific surface degradation.…”

“…Therefore, it is recommended to cover bulk-fill composites with silorane-based composite in order to delay surface degradation, which is in line with previous recommendations by Leprince and others 43 and Sunbul and others. 52 The change in the Pearson correlation test between the DE and DD from strongly correlated at 40 days to weakly correlated at 60 days may indicate that repolishing followed by further immersion influences this correlation. This is in partial harmony with the findings of Soares-Geraldo and others, 24 who reported a significant positive correlation between the DE and DD and showed that not all color alterations were associated with surface degradation.…”

“…The negative values may mask the actual properties of the materials tested with regard to SO (24). Previous studies have also reported negative SO values for Tetric EvoCeram bulk fill (21,25). It has been suggested that this finding is related to incomplete dehydration and the formation of metal hydroxides within the RBC (21).…”

Objective: This study aimed to investigate and compare the water sorption (WS), solubility (SO) and surface roughness (SR) of four bulk fill resin-based composites (RBCs), a conventional flowable RBC and a conventional hybrid RBC. MaterialsandMethods:Disc-shaped specimens of 3 low-viscosity bulk fill RBCs (SureFil SDR flow, X-tra base, Filtek Bulk Fill flow), 1 high-viscosity bulk fill RBC (Tetric EvoCream Bulk Fill), 1 conventional low-viscosity flowable RBC (Filtek Ultimate flow) and 1 conventional hybrid RBC (Filtek Z250) (n=10) were prepared and immersed in distilled water for 28 days. Upon removal, specimens were weighed using an electronic scale to determine WS and SO based on weight gain/loss, and surface profilometry was performed to determine SR. Data were analyzed using one-way ANOVA and Tukey's post-hoc tests (p=0.05). Results: WS and SO showed significant, positive correlations (r=0.612; p<0.001), and both varied significantly among the materials, with WS and SO values of both high-filled and low-filled bulk fill RBCs lower than their conventional counterparts. Moreover, SR values of both bulk and conventional flowable low-fill RBCs were significantly lower in comparison to the high-fill RBCs (p<0.05). Conclusion: WS, SO and SR of RBCs are material-dependent and highly affected by filler loading and resin matrix composition. Bulk fill RBCs can be used in a large variety of clinical situations in line with the manufacturers' recommendations. Amaç: Bu çalışmanın amacı dört farklı bulk fill kompozit rezin ile bir adet geleneksel akışkan kompozit ve bir adet geleneksel hibrit kompozitin su emilimi, çözünürlük ve yüzey pürüzlülüğü değerlerini karşılaştırmalı olarak incelemektir. Gereç ve Yöntemler: Üç adet düşük viskoziteli bulk fill kompozit (SureFil SDR flow, X-tra base, Filtek Bulk Fill flow), bir adet yüksek viskoziteli bulk fill kompozit (Tetric EvoCream Bulk Fill), bir adet geleneksel düşük viskoziteli akışkan kompozit (Filtek Ultimate flow) ve bir adet geleneksel hibrit kompozit (Filtek Z250) kullanılarak disk şeklinde örnekler hazırlanıp distile suda 28 gün bekletilmiştir (n=10). Örnekler elektronik bir terazide tartılarak kütle kazanım ve kayıp değerlerine göre su emilimi ve çözünürlük değerleri hesaplanmıştır. Daha sonra yüzey pürüzlülüğü ölçümü için profilometre cihazı kullanılmıştır. Elde edilen veriler tek yönlü ANOVA ve Tukey post-hoc testleri ile analiz edilmiştir (p=0,05).

“…The area of use in dentistry for resin-based composites is a broad spectrum, from small areas of decay to direct restorations of heavily damaged teeth (48). The reasons for selecting these composites is that the majority have the potential to mimic the aesthetic nuances of dental tisssues (49).…”

In the field of restorative dentistry, the use of composites has become widespread with increasing aesthetic demand. Nowadays the composites are divided into various classes depending on the type and size of the filler particles. Apart from this, many new composites have been produced in order to protect the healthy tooth structure, to reduce microleakage and secondary caries formation, to reduce marginal pigmentation and postoperative sensitivity together with developments in technology. The aim of this review is to improve the clinical performance and to evaluate new composite resins that will provide more selection criteria for dentists.
