“…Moreover, this device has a wavelength of only one profile, and knowing that Filtek One Bulk Fill contains camphorquinone as the only photoinitiator, it would allow the total absorption of the light, favouring the bond strength. The presence of zirconia/silica also improved the mechanical properties of Filtek One Bulk Fill, which is supported by the results obtained by Kiliç et al 44 …”

Aim This study aimed to evaluate the effects of polywave and monowave light-emitting diode curing units on the microtensile bond strength and failure types of three bulk-fill resin composites. Materials and Methods This in vitro experimental study was performed on 180 microbars obtained from human third molars and were distributed into 12 groups according to the type of bulk-fill resin composite and the light-curing unit. Third molars were restored using Filtek One Bulk Fill Restorative, Tetric ® N-Ceram Bulk Fill, and Opus Bulk Fill resin composites was light-cured with Elipar Deep Cure L and Valo in three modes: standard, high power, and extra power. Subsequently, microtensile analysis was carried out with a universal testing machine and the type of failure with an optical stereomicroscope. For statistical analysis, the Kruskal–Wallis H-test was used, with the Bonferroni post hoc test and Fisher’s exact test, considering a significance of p<0.05. Results There were significant differences in the microtensile bond strength between the Filtek One Bulk Fill restorative and Opus Bulk-Fill (p = 0.042) when light was cured with the polywave unit at standard power. On the other hand, the Filtek One Bulk Fill Restorative and Opus Bulk Fill resins showed significant differences in microtensile bond strength when light was cured with the monowave unit compared with the polywave unit (p<0.05). Conclusion The presence of alternative photoinitiator systems that are more reactive than camphorquinone produced higher microtensile bond strength in Tetric N-Ceram Bulk Fill and Opus Bulk Fill resins when light-cured with a high and standard polywave unit, respectively, compared to Filtek One Bulk Fill resins. Finally, Tetric N-Ceram Bulk Fill and Opus Bulk Fill resins had the highest percentage of mixed failures, while Filtek One Bulk Fill resin had adhesive failures, which was related to its lower microtensile bond strength.

“…26 In another study investigating the effect of LCUs on the bonding strength in the repair of different composites with bulk-fill composites, the Elipar DeepCure-S provided better bonding strength than the Valo light device, and this was attributed to the Elipar DeepCure-S light device providing better polymerization at the bottom of the composite. 27 All light curing units used in the study has provided significantly high polymerization depths at 40 second compared to 10 and 20 seconds (p<0.05). This can be explained by prolonged curing times allow the formation of additional cross-links in higher depths of restorative material and lead to a more homogeneous polymer network.…”

To evaluate the effect of two second generation LED Light curing units and a third-generation polywave LED Ligth curing unit at three different irradiation durations on surface microhardness and detpth of cure of nano-hybrid composite resin material.Materials and Methods: Elipar TM S10, Elipar TM Deep Cure-S, VALO Cordless, was evaluated at 10s, 20s, 40s curing periods in this study. A nano-hybrid composite Filtek TM Z550 that contains camphorquinone as photoinitiator is used as test material. For microhardness test ninety 6 mm diameter, 4 mm deep cylindrical composite blocks in teflon molds were prepared. For each light source at each application times 10 specimen were prepared (n=10) and tested. Also ninety, 4 mm diameter, 6 mm deep cylindrical composite specimens in a split aluminum mold polymerized with three different light sources at three different durations (n=10) were tested for depth of cure measurement. Data were analyzed statistically by SPSS (Ver: 22.0) one-way ANOVA and multiple comparisons were performed by Tukey's posthoc test. A p-value less than 0.05 was considered statistically significant. Results:The values of cure depth were found significantly higher at 40 seconds of irradiation time for all light sources used (p<0.05). Elipar Deep Cure-S showed the higher top surface microhardness at 40s polymerization (p<0.05) Conclusions: All light devices used in the study provided adequate polymerization of the nano-hybrid composite at all application durations in this study. The highest polymerization depth and microhardness values were achieved at 40 sec. polymerization time for all LCUs.

“…36 The data of this study are in agreement with those of previous studies. 9,36,56,58 However, it has also been reported that the composite bond strength decreases after performing a higher number of thermal cycles. 59 Present study established a statistically significant decrease in the repair shear bond strength values after thermal cycling only in the chlorhexidine group (Table 1).…”

Materials and Methods: 100 cavities (2 mm deep, 3 mm diameter) prepared in acrylic blocks were filled with silorane composite and subjected thermal cycle and divided into 5 groups (N=20). Group 1: Chlorhexidine; Group 2: Ozonated-water; Group 3: Nd:YAG-laser; Group 4: Er:YAG-laser; Group 5 (control): untreated. And disinfection method treated according to the groups. Composite repair procedure was implemented with the same silorane based composite. Groups divided into 2 subgroups (n=10). One of the subgroups for each group was subjected second thermal cycle. All of the samples tested by a universal test device. Data were statistically analyzed and significance test of the difference between the two means, the variance analysis, and Student-t Test used.Results: No statistical difference was observed among groups after first thermal cycle (p>0.05). After the composite repair, there were no statistically significant difference between groups that were subjected to second thermal cycle (p>0.05). When each group was evaluated in themselves on comparing before and after the thermal cycle after the repair operation; as no statistically significant difference between Ozonatedwater, Nd:YAG, Er:YAG and Control groups (p>0.05), a statistically significant decrease was observed only in the Chlorhexidine group after thermal cycle (p<0.05).Conclusions: Ozonated-water, Nd:YAG-laser and Er:YAG-laser applications can be used in the repair of silorane-based composite restorations as an alternative antibacterial application, since the application of chlorhexidine reduces the repair bonding strength.
