“…Loss of edge harmony between the tooth tissue and the material, interruption of the connection between the interface, application-related errors, and polymerization shrinkage can all play a role. This situation leads to microleakage, marginal coloration, and secondary caries [ 8 , 10 ]. Mahmoud et al reported that coloration occurring between untreated enamel surfaces and the residual composite surplus could also be a factor [ 24 ].…”

“…Despite this, this is a time-consuming process in the case of deep cavities and in the case of contamination between the increments, and carries an increased risk of air bubble development [ 8 ]. Such factors as the resin shade/type filler amount and the intensity and spectrum of the activation light were all found to have a bearing on the cure depth of the resin composite [ 9 , 10 ]. These need to be accompanied by qualities of good adaptation and low residual stress, as required for all materials and filling techniques, and are essential through polymerization [ 10 ].…”

“…It is recommended that the composite is placed in the cavity using the incremental technique. Bulk-fill-type composite materials have been developed to facilitate material placement and polymerization [ 9 , 10 ]. The term “bulk technique” is used because the chemically polymerized composites are placed into the cavity in a single layer.…”

Background: The aim of this split-mouth design research was to compare the clinical performance of a glass-ionomer cement system on Class I/II cavities against the clinical performance of bulk-fill resin composite restoration materials. Methods: Thirty-five patients were randomized and enrolled in the study, aged between 10 and 12 years, all of whom had a matched pair of permanent mandibular carious molars with similar Class I/II. A total of 70 restoration placements were performed. The patients were each given two restorations consisting of either a glass-ionomer cement with a nano-filled coating or a bulk-fill resin composite after the use of a self-etch adhesive. The cumulative survival rates were estimated using log-rank test and the Kaplan–Meier method. For comparison of the restorative materials in line with the modified Ryge, the McNemar test and the Wilcoxon signed rank test were employed. Results: With regard to retention, the glass-ionomer cement system and bulk-fill resin composite performed similarly in permanent molars in Class I/II cavities over a period of up to 24-months (p > 0.05). Over the 24-month period, Class I restorations showed statistically better survival rates than Class II restorations (p < 0.05). In the case of glass-ionomer cement systems, over the two-year period, more common chipping and surface degradations were observed. Conclusions: The glass-ionomer cement system and bulk-fill resin composite restorative materials display good clinical performance over a period of 24-months.

Diş hekimliğinde kullanılan restoratif materyallerdeki gelişmeler, amalgam ile restore edilebilen geniş posterior kavitelerde kompozit rezinlerin kullanımına olanak sağlamıştır. Posterior dişlerin restorasyonunda kullanılan kompozit rezin materyallerin mekanik ve estetik özelliklerinin geliştirilmesi kullanım kolaylığı beklentisini beraberinde getirmiştir. Bu amaçla kullanılan bulk tekniği ve bu teknikle uygulanan kompozit rezin materyaller son yıllarda yaygın olarak kullanılmaktadır. Kompozit rezinlerdeki gelişmelere rağmen bu restorasyonlarda zaman içerisinde oluşan problemler genellikle kompozitlerin polimerizasyon büzülme stresi ile ilişkilendirilir.Polimerizasyon büzülmesini azaltmak amacıyla kompozitlerin inkremental teknik ile (tabakalar hâlinde) uygulanması önerilmektedir. Fakat kompozitlerin inkremental yerleştirmesi derin kavitelerde ışınlama sayısını ve uygulanma süresini artırmaktadır. Yeni nesil bulk fill kompozitler gelişmiş translusent yapı ve farklı fotoaktif başlatıcı içermektedirler. Bu özellikleri nedeniyle diş kavitelerine daha büyük kütleler hâlinde yerleştirilebilmektedir. Bu kompozitlerin geleneksel kompozitlere göre artan ışınlama derinliği ve polimerizasyon büzülme stresini azaltılması, restoratif diş hekimliğinde heyecan uyandıran bir yenilik olmuştur. Bu derlememizin amacı; yeni nesil bulk fill kompozitleri ticari örnekleri ile analiz ederek, bu kompozitlerin özellikleri, avantajları ve kullanımları hakkında bir literatür incelemesi sunmaktır.

Investigating the Cytotoxicity of Dual-Cure Bulk-Fill Resin Materials on L929 Cells

The aim of this in vitro study was to investigate cytotoxic effects of dual-cure bulk-fill resin materials polymerized with a third-generation LED light-curing unit (LCU) on L929 fibroblast cells in terms of morphology and viability. Three novel dual-cure, flowable bulk-fill materials (Fill-Up!™), a bioactive material (ACTIVA™ BioACTIVE-RESTORATIVE™), and a dual-cure bulk-fill composite material (HyperFIL® HAp) polymerized by LED LCU (VALO™ Cordless) were tested. Each material was placed in plastic rings (4 mm × 5 mm) in a single layer. Unpolymerized rings filled with each material were placed in direct contact with cells and then polymerized. After polymerization, the removed medium was readded to wells. In this study, four control groups were performed: the medium-free control group, medium control group, physical control group, and light applied control group. Three samples were prepared from each group. After 24 h, the morphology of cells was examined and a WST-1 test was performed. The percentage of cell viability (PCV) of each group was calculated. The experiment was repeated three times. Data were analyzed by a Kruskal–Wallis Test and a Mann–Whitney U test. p < 0.05 was considered significant. The PCV of all groups were found to be significantly lower than the medium control group (p < 0.05). The lowest PCV was obtained in HyperFIL® Hap, while highest was in the Fill-Up!™. In the morphology of cells related to the experimental groups, it was observed that the spindle structures of cells were disrupted due to cytotoxicity; cells became rounded and intercellular space increased. There were no significant differences between the control groups (p > 0.05). All control groups showed acceptable PCV (>70%) and cells were spindle-like, similar to the original fibroblast cells. It can be suggested that clinicians should pay attention when applying dual-cure bulk-fill materials in deep cavities, or they should use a liner material under these materials.
