Forty caries-free primary teeth were acquired and mounted into self-curing acrylic resin.
The prepared samples were then randomly divided into four subgroups, according to the bonding system to be applied; specimens of each group were stored separately to prevent mixing between the groups. A custom made hollow split mold with an internal diameter of 2mm and height of 5mm was held on adhesive treated surface of the specimens and then composite resin (Esthet X HD, Dentsply, New York, USA) was placed inside the mold, condensed and light-cured (Gnatus, Brazil) for 40 sec. Following curing, the metal mold was split and removed. All the specimens were immersed in water for 24 hours.
Then tensile bond strength was measured using an Instron universal testing machine (Instron 5566, USA) at a crosshead speed of 0.5 mm/min.
All data were subjected to statistical analysis using SPSS (Statistical Package for Social Sciences) Version 15.0 statistical analysis software and the Kruskal-Wallis test and Dunn’s test.

Six resin composite materials were tested in this study: two flowable bulk-fill composites [SDR (Dentsply DeTrey, Konstanz, Germany) and x-tra base (VOCO, Cuxhaven, Germany)], two high-viscosity bulk-fill composites [Bulk Ormocer (VOCO) and SonicFill (Kerr, Orange, CA, USA)], a conventional flowable composite [Esthet X flow (Dentsply DeTrey)], and a conventional high-viscosity composite [Esthet X HD (Dentsply DeTrey)]. Details of the test materials are given in Table 1. In all tests, photoactivation was performed using an LED light curing unit (Bluephase G2; Ivoclar Vivadent, Schaan, Liechtenstein) with a 10-mm diameter light emission window. Output irradiance (1,275 mW/cm 2 ) of the curing light was measured with a calibrated FieldMaxII-TO power meter in conjunction with a PM2 thermopile sensor (Coherent, Santa Clara, CA, USA), and checked periodically during the study.
Experimental testing was conducted inside a temperature-controlled chamber at 25°C [21] , which simulates intraoral temperature conditions after rubber dam placement [37] .

Thirty-two caries-free primary teeth were acquired and the occlusal surface of each tooth was ground to expose the dentin, following which bonding agents were applied; then blocks of composite resin (Esthet X HD, Dentsply) were built using custom-made hollow split molds. The sample teeth were divided into two equal halves vertically using a diamond disc. The sectioning was done under running water. The sectioned halves were then embedded into self-cure resin, keeping the resin-dentin interface exposed (for examination). The samples were sequentially polished with 600 and 1200 grit abrasive papers and Sof-lex finishing and polishing systems.

The resin composites investigated were Tetric EvoCeram Bulk-fill (TEC), a regular-viscosity bulk-fill composite resin (Ivoclar Vivadent, Schaan, Liechtenstein), Surefil SDR Flow (SDR), a low-viscosity bulk-fill composite (Dentsply Caulk; Milford, DE, USA), and Esthet-X HD (EHD), a nanohybrid composite (Dentsply Caulk; Milford, DE, USA) as control (Table 1).
Delrin ® washers (outer diameter: 19 mm; inner diameter: 6.4 mm) with 1, 3 and 5 mm thickness were filled with TEC, SDR, or EHD, covered with Mylar ® strips on both sides and then pressed between two glass plates by hand pressure to expel excess material which was removed to assure the thickness of the composite material in washer. Each filled washer was cured with a light curing unit Bluephase ® G2 (Irradiance: 1,275 mW/cm 2 , Ivoclar Vivadent, Schaan, Liechtenstein) for 40 s. The procedure yielded nine standard composite filled washers; they were 1-mm, 3-mm and 5-mm thick of cured composite discs for each of the three materials investigated for later use.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
