After adhesive treatment, the cavities were restored either with bulk (group 1) or layered (group 2) short-fiber-reinforced resin composites (SFRC); bulk-fill RC (group 3); and layered conventional RC (control). Right after the polymerization and a week later, crack evaluation on the outer surface of the remaining cavity walls was performed with a transillumination method utilizing the D-Light Pro (GC Europe) with the "detection mode." Between- and within-groups comparisons Kruskal-Wallis and Wilcoxon tests were used, respectively.Post-polymerization crack evaluation showed significantly lower crack formation in SFRC groups compared to the control (p<0.001). There was no significant difference within SFRC groups and non-SFRC groups (p=1.00 and p=0.11, respectively). Within group comparison revealed significantly higher number of cracks in all groups after 1 week (p≤0.001), however, only the control group differed significantly from all the other groups (p≤0.003).Post-polymerization shrinkage induced further crack formation in the tooth 1 week after the restoration. SFRC was less prone to shrinkage-related crack formation during the restorative procedure; however, after 1 week, besides SFRC, bulk-fill RC also showed less prone to polymerization shrinkage-related crack formation than layered composite fillings.SRFC can decrease the shrinkage stress-induced crack formation in MOD cavities.

(SE, SZTE admin5) AB - Bevezetés: Kutatásunkban arra kerestük a választ, hogy két eltérő töméstechnika esetében van-e különbség a rövidüvegszál megerősítésű kompozit (short fiber-reinforced composite, SFRC) tömőanyag zsugorodása miatt kialakult repedésekszámában.Anyag és módszer: Két csoportban, 20-20 extrahált bölcsességfogba standardizált nagyságú MOD üreget preparáltunk,majd a fogakat az alábbiak szerint restauráltuk SFRC-vel: 1. csoportnál bulk, rétegzés nélküli technikával, 2. csoportbanpedig ferde rétegzéssel 2 mm vastag rétegekben. Mindegyik minta esetén az SFRC-t 1 mm kompozittal fedtük.A tömés elkészítését követően D-Light Pro lámpával megvizsgáltuk a fogzománcot, és a keletkezett repedések számátrögzítettük. Az összrepedésszámot egy hét elteltével is rögzítettük.Eredmények: A két töméstechnika között az eltérés nem szignifikáns a repedésszám tekintetében. 1 héttel későbba bulk, rétegzés nélküli csoportban 4,95 (340%-os növekedés), a rétegzéses csoportban 4,30 (410%-os növekedés) voltaz átlagos repedésszám. Ez a korábbi adatokhoz képest szignifikáns eltérés (p = 0,000). A két töméstechnika közötta végső összrepedésszám tekintetében nem tapasztaltunk szignifikáns eltérést.Következtetések: SFRC anyag esetén a vizsgált két töméstechnikával közel azonos mértékű repedésképződés jönlétre, és mindkét esetben jelentősen megnő a repedések száma a posztpolimerizációs időszakban.

AB - The aim of this research was to evaluate the mechanical impact of different direct restorations in terms of fracture resistance, and subsequent fracture pattern, in occlusal high C-factor cavities. Furthermore, the adaptation of different direct restorations in the form of gap formation was also evaluated. Seventy-two intact mandibular molars were collected and randomly distributed into three groups (n = 24). Class I occlusal cavities with standardized dimensions were prepared in all specimens. After adhesive treatment, the cavities were restored with direct restorations utilizing three different materials. Group 1: layered conventional packable resin composite (Filtek Ultimate), Group 2: bulk-fill resin composite (SDR), Group 3: bulk-fill short fibre-reinforced composite (SFRC; everX Posterior) covered with packable composite occlusally. Half of the restored specimens underwent static load-to fracture testing (n = 12/group), while the rest underwent sectioning and staining for microleakage evaluation and gap formation analysis. Fracture patterns were evaluated visually among the mechanically tested specimens. The layered composite restoration (Group 1) showed significantly lower fracture resistance compared to the bulk fill groups (Group 2, p = 0.005, Group 3, p = 0.008), while there was no difference in fracture resistance between the other groups. In terms of gap formation values, the layered composite restoration (Group 1) produced significantly higher gap formation compared to the bulk-fill groups (Group 2, p = 0.000, Group 3, p = 0.000). Regarding the fracture pattern, SFRC (Group 3) produced the highest number, while SDR (Group 2) produced the lowest number of repairable fractures. The use of bulk-fill resin composite (fibre or non-fibre-reinforced) for occlusal direct restorations in high C-factor cavities showed promising achievements regarding both fracture resistance and microleakage. Furthermore, the use of short fibre-reinforced bulk-fill composite can also improve the fracture pattern of the restoration-tooth unit. Bulk-fill materials provide a simple and effective solution for restoring and reinforcing high C-factor occlusal cavities.

AB - OBJECTIVES: The aim was to investigate the fatigue performance of endodontically treated (ET) molars restored by various dentin-replacing materials and material configurations. Moreover, the impact of additional adhesive treatment with glass-ionomer cement (GIC) was evaluated.; METHODS: 250 intact molars were collected and randomly distributed into ten groups (n=25). After endodontic procedure standard Class I cavities were prepared and restored with different direct restorative techniques and dentin-replacing materials. Two-group were restored with either packable or flowable short fiber-reinforced composites (SFRCs). Two-group were restored by experimental fiber-reinforced GIC with and without adhesive treatment. Four-group were restored by conventional and resin-modified GICs with or without adhesive treatment. One-group was restored with a dual-cure composite resin and last group was restored with only conventional composite resin (control). Fatigue-survival was measured for all specimens using a cyclic-loading machine until fracture occurred or a number of 40.000 cycles were achieved. Kaplan-Meyer survival analysis was conducted, followed by pairwise log-rank post hoc comparisons. Fracture mode was then examined by means of optical microscopy and SEM.; RESULTS: Group restored with flowable SFRC showed significantly higher survival (p<0.05) compared to all of the groups, except for group restored with packable SFRC (p>0.05). Group restored with fiber-reinforced GIC had significantly (p<0.05) higher survival rates compared to other commercial GICs. SEM demonstrated change of the fracture line when fracture reached the SFRC layer.; SIGNIFICANCE: Direct restoration of Class I in ET molars with the use of SFRCs as dentin-replacing materials demonstrated its ability to reinforce the dental structures and to increase the fatigue resistance in this specific clinical situation.
