“…Autorzy odnotowali także wyższe wartości modułu sprężystości dla materiałów X-Flow i Tetric EvoFlow opartych na tradycyjnych dimetakrylanach, a jak wiadomo występuje dodatnia korelacja między wartością modułu sprężystości a wartością naprężeń skurczowych sieciujących materiałów kompozytowych. Wyniki badań Tiba et al [24] potwierdzają korzystne właściwości żywic opartych na zmodyfikowanych monomerach uretanowych i etoksylowanym monomerze Bis-EMA, które mimo relatywnie wysokich wartości skurczu polimeryzacyjnego wykazują małe naprężenia skurczowe, niższe w porównaniu z materiałami o tradycyjnym składzie matrycy polimerowej. Inni autorzy w badaniach tensometrycznych także stwierdzili wyższe naprężenia skurczowe materiałów o tradycyjnym składzie matrycy polimerowej: Filtek Supreme XT Flowable [25] oraz Filtek Supreme Ultra Flowable [26] w porównaniu z materiałami o zmodyfikowanym składzie matrycy polimerowej: Tetric EvoFlow Bulk Fill [25] oraz Filtek Bulk Fill Flow, SDR i Venus Bulk Fill [26].…”

Wiązaniu materiałów kompozytowych towarzyszy skurcz polimeryzacyjny, który wywołuje naprężenia skurczowe w materiale i otaczających go tkankach zęba i jest przyczyną powikłań klinicznych. Podczas wykonywania wypełnień kompozytowych ważne jest ograniczenie naprężeń skurczowych powstających na granicy wypełnienie-tkanki zębów. W celu ograniczenia naprężeń generowanych przez sieciujący materiał kompozytowy proponuje się wykorzystanie nowo opracowanych materiałów kompozytowych o zmodyfikowanym składzie matrycy polimerowej. O wartości powstałych naprężeń decyduje wielkość skurczu polimeryzacyjnego, ale także sprężystość materiału kompozytowego. Nieliczne analizy oceniające naprężenia skurczowe powodowane przez materiały o zmienionej matrycy polimerowej skłoniły autorów do podjęcia badań w tym temacie. Cel pracy. Ocena wartości naprężeń skurczowych powstających podczas polimeryzacji różnych materiałów kompozytowych typu flow o zmodyfikowanej matrycy polimerowej w porównaniu z półpłynnymi kompozytami o tradycyjnym składzie matrycy polimerowej. Materiał i metody. W badaniach elastooptycznych na płytkach z optycznie czułej żywicy epoksydowej przeprowadzono elastooptyczne pomiary wielkości naprężeń zredukowanych oraz analizę stanu naprężeń wokół wykonanych wypełnień. Pomiary przeprowadzono z użyciem polaryskopu kołowego FL200/Gunt, wykorzystując do analizy komputerowy program Met-Ilo przeznaczony do ilościowej analizy obrazów. Na podstawie wzorów teorii spręży-stości obliczono naprężenia spowodowane skurczem wypełnień kompozytowych. Wyniki. W badaniach uzyskano różne wartości naprężeń generowanych przez poszczególne materiały kompozytowe. Oceniane materiały kompozytowe różniły się istotnie pod względem naprężeń skurczowych powstających podczas polimeryzacji. Najmniejsze naprężenia generowały materiały o zmodyfikowanym składzie matrycy polimerowej 4,7-8,4 MPa w porównaniu z kompozytami o tradycyjnym składzie matrycy 9,5-17 MPa. Wnioski. Materiały kompozytowe o zmodyfikowanej matrycy polimerowej w porównaniu z materiałami o tradycyjnym składzie matrycy powodują mniejsze naprężenia skurczowe (Dent. Med. Probl. 2015, 52, 4, 424-433).Słowa kluczowe: półpłynne materiały kompozytowe, matryca polimerowa, skurcz polimeryzacyjny, naprężenia skurczowe. AbstractBackground. Resin composite polymerization is associated with shrinkage that causes shrinkage stress in material and surrounding tooth structure and results in clinical complications. During the placement of composite restoration, it is important to limit shrinkage stress generated at the composite-tooth structure interface. Recently developed composite resins with modified composition of polymer matrix may be indicated to limit stress generated by cross-linking composite resin. The generated stress is determined by the value of polymerizatio...

“…In the study of Tiba et al [26], multiple bulk-fill (flowable and high viscosity) and incremental-fill resin composites were evaluated regarding depth of cure to be acceptable according to international standard 4049 [27]. Three of the high viscosity bulk-fill resin composites (SonicFill, Kerr; Tetric EvoCeram Bulk Fill, Ivoclar-Vivadent; Alert Condensable Composite, Pentron), one flowable bulk-fill composite (Filtek Bulk Fill Flowable Restorative, 3M ESPE), and one incremental-fill composite (Heliomoler HB, Ivoclar-Vivadent) did not achieve adequate depth of cure according to the standard.…”

“…In the same study, it was mentioned that x-tra base, although being a low viscosity bulk-fill material, showed a higher VHN than that of Tetric EvoCeram Bulk Fill, a high viscosity bulk-fill material. Tiba et al [26] assessed the Knoop hardness ratio of several bulk-fill versus incremental-fill resin composites and stated that all bulk-fill composites tested, except one (Alert Condensable Composite) exhibited adequate hardness ratio that is comparable to that of the conventional incremental-fill composites. However, in other investigation, it was reported that the surface hardness of some of bulk-fill composite materials was significantly decreased after ethanol storage, which raises distress about long-term stability of these materials [29].…”

Objective: The aim of this study was to evaluate the degree of conversion and surface hardness of two bulk-fill composites and one incremental-fill composite. Methods: Bulk-fill composites (x-tra fil, Voco; QuiXfil, Dentsply) and incremental-fill composite (Grandio, Voco) were used. Twenty five cylindrical specimens (5 Â 4 mm) were made from each material in Teflon molds. Mold was filled in one increment for the bulk-fill composites and in two increments for the incremental-fill composite. Specimens were stored dry in dark at room temperature for 24 h before testing. Degree of conversion (DC) was determined using Fourier transform infrared spectroscopy (FTIR). A microhardness tester was used to measure the Vickers hardness number (VHN) on top and bottom surfaces of each specimen. Data for DC and VHN were analyzed by ANOVA and pair-wise Newmanekeuls test. Results: X-tra fill recorded significantly the highest DC, while no significant difference was noted between the other two composites. The VHN mean values of all composites tested were significantly different from each other (P < 0.0001), either in top or bottom surface, with Grandio showed the highest mean value and QuiXfil showed the lowest mean value. Only QuiXfil recorded no significant VHN difference between its top and bottom surfaces. There was no significant difference in bottom/top hardness ratio% among materials. Non significant Correlation between VHN and DC was noted. Conclusions: X-tra fil showed the most DC performance. Incremental-fill composite showed higher VHN than bulk-fill composites. Differences in DC and VHN values among materials proved to be a material dependent.

“…Com a demanda por procedimentos clínicos mais rápidos e mais simples, um material restaurador tem obtido popularidade, a classe dos compósitos Bulk Fill. O seu uso permite a redução do tempo de trabalho ao diminuir o número de incrementos inseridos na cavidade a ser restaurada, uma vez que permite a polimerização efetiva de camadas de até quatro milímetros 7 , enquanto que os compósitos convencionais são tipicamente colocados em incrementos de, no máximo, dois milímetros 8 . Essa diminuição de tempo ocorre mesmo quando existe a indicação de se realizar uma camada final com um compósito convencional 9 .…”

ResumoIntrodução: A classe dos compósitos Bulk-Fill tem obtido popularidade com a promessa de ser fotopolimerizado efetivamente em camadas de até quatro milímetros, fato que contrasta com os dois milímetros requisitados para os compósitos convencionais para manutenção da adesividade da restauração. Objetivo: O objetivo deste estudo foi analisar a resistência de união à dentina de restaurações confeccionadas com compósitos do tipo Bulk-Fill. Material e método: Foram utilizados 15 terceiros molares humanos, cuja superfície oclusal foi cortada e a dentina foi exposta. Esses elementos dentários foram divididos em três grupos conforme o material restaurador utilizado. O sistema adesivo usado foi o mesmo para todos os grupos. Posteriormente, os dentes restaurados foram cortados para originar palitos de aproximadamente 1 mm de largura, 1 mm de profundidade e 8 mm de altura, que foram fixados às garras do dispositivo de microtração. Foram utilizados dez palitos de cada dente, totalizando 50 palitos por grupo. Os dados de resistência de união à microtração foram expressos em megapascal (MPa). As fraturas foram analisadas em microscópio óptico. Os dados foram analisados através dos testes ANOVA e Tukey (p<0,05). Resultado: Os três compósitos estudados diferiram estatisticamente entre si (p<0,000). Os compósitos Bulk-Fill apresentaram resistências de união semelhantes e superiores ao convencional (p<0,000). A fratura mais encontrada foi a mista, em todos os grupos. Conclusão: Os compósitos Bulk-Fill apresentaram maiores valores de resistência de união com a técnica restauradora utilizada.Descritores: Resinas compostas; resistência à tração; dente molar. AbstractIntroduction: The class of the Bulk Fill composites has gotten popularity with the promise of been cured effectively of layers up to 4 mm, a fact with contrasts with the 2 mm required for the convencional composites for maintance of the restoration's adhesion. Objective: The aim of this study was evaluate the microtensile bond strength to dentine of restorations made with Bulk Fill composites. Material and method: 15 thirds molars teeth were utilized, whose occlusal layer was cut, exposing the teeth dentine. The teeth were divided in three groups according to the type of restoration materials. All groups were treated with the adhesive system Adper Single Bond 2. Subsequently they were cut in sticks with approximately 1 mm wide, 1 mm depth and 8 mm high, that were fixated at a universal microtensile maching. 10 sticks of each tooth were used in the experiment totaling 50 sticks per group. The data of bond strength microtensile were expressed in MPa. The failures mode was evaluated at an optical microscope. The Data were statistically analyzed through ANOVA and Tukey test (p<0.05). Result: The three composites studied differed statistically among themselves (p<0.000). The Bulk Fill composites had microtensile bond strength similar and higher than the convencional (p<0.000). The pattern failure mode found in all groups studied was the mixed. Conclusion: The Bulk Fill c...
