Conventional composites Charisma Classic (CC; Kulzer, Hanau, Germany) and Filtek Ultimate Universal Restorative (FU; 3M, St. Paul, MN, USA), “BPA-free” composites Charisma Diamond (CD; Kulzer, Hanau, Germany) and Admira Fusion (AF; Voco, Cuxhaven, Germany), and RM-GICs Photac Fil Quick Aplicap (PF; 3M) and GC Fuji II LC Capsule (F2; GC, Tokyo, Japan) were investigated. According to the material safety data sheets, CC contains Bis-GMA, while FU contains Bis-GMA and ethoxylated Bis-GMA (Bis-EMA). The presence of BPA-based monomers in the examined “BPA-free” composites and RM-GICs was not officially disclosed; however, previous studies identified Bis-EMA in PF [29 (link)] and Bis-GMA in F2 [29 (link),30 (link)]. The composition of the materials is summarized in Table 1 .

The fissure sealants tested in this study were Fissurit (Voco Gmbh, Cuxhaven, Germany), Grandio Seal (Voco Gmbh, Cuxhaven, Germany), and Admira Fusion (Voco Gmbh, Cuxhaven, Germany). The specifications of the adhesive system used and of all fissure sealants tested are listed in Table 1 .
The fissure sealants were applied to the demarcated enamel area using silicon rings (height 2 mm; internal diameter 6 mm; external diameter 8 mm) to obtain specimens identical in size. The cavity of these rings were slightly overfilled with each sealant, covered with a Mylar strip (Henry Schein, Melville, NY, USA), and pressed against a glass plate. All specimens were then light-cured using a LED curing light in soft start-polymerization mode (Celalux 2 High-Power LED curing-light, Voco GmbH, Cuxhaven, Germany) for the times suggested by the manufacturers at an irradiance of 1000 mW/cm2. The light was perpendicular to the specimen surface at a distance of 1.5 mm. Following polymerization, specimens were stored in distilled water for 24 h at 37 °C. For each of the four groups described ahead we obtained 20 specimens for each fissure sealant.

Nine bulk-fill resins -Aura Bulk Fill (SDI, Australia), Filtek Bulk Fill Flow (3MESPE, Germany), Filtek Bulk Fill Sculptable (3MESPE, Germany), Surefil SDR + (Dentsply, Germany), Tetric EvoFlow Bulk Fill (Ivoclar-Vivadent, Liechtenstein), Admira Fusion (Voco, Germany) X-tra Fil (Voco, Germany), X-tra Base (Voco, Germany), Opus (FGM, Brazil); and two conventional resins -Filtek Z350XT (3MESPE, Germany) and Filtek Z350 Flow (3MESPE, Germany), were evaluated (Table 1).
Samples of each material with 5 mm in diameter and 2 mm and 4 mm in thickness were prepared for assessment of degree of conversion and Vickers hardness. In order to avoid inhibition of oxygen, a transparent polyester strip was placed on the top and bottom of the mold, and resins were inserted and photopolymerized with a LED device (KaVo Poly Wireless, KaVo -Brazil) according to the manufacturer's instructions (Table 1). All specimens were stored in distilled water for 24 h at 37°C prior to testing. For the cytotoxicity test, discs of each material (5 x 4 mm, n = 2) were prepared under aseptic conditions, using sterile material and a laminar flow cabinet, to reduce any risk of biological contamination of the cells. Thereafter, the samples were placed in 24-well plates with 200 µL of culture medium (RPMI -1640) at two different time intervals (72 h and 7 days) at 37ºC and 5% CO 2 , to obtain the extracts.

Eleven resins (Table 1) were evaluated in this study: nine bulk-fill composites -Aura Bulk Fill (SDI, Australia), Filtek Bulk Fill Flow (3MESPE, Germany), Filtek Bulk Fill Sculptable (3MESPE, Germany), Surefil SDR + (Dentsply, Germany), Tetric EvoFlow Bulk Fill (Ivoclar-Vivadent, Liechtenstein), Admira Fusion (Voco, Germany), X-tra Fil (Voco, Germany), X-tra Base (Voco, Germany), Opus (FGM, Brazil), and two conventional resins -Filtek Z350XT (3MESPE, Germany) and Filtek Z350 Flow (3MESPE, Germany).
For energy-dispersive X-ray spectroscopy (EDS), DC, and VMH analyses, specimens obtained from each material, measuring 5 mm in diameter and 4 mm in thickness, were prepared. In order to prevent oxygen inhibition, a transparent polyester strip was placed on the top and bottom of the mold, and resins were inserted and photopolymerized with a LED device (KaVo Poly Wireless, KaVo -Brazil) in compliance with the manufacturer's instructions (Table 1). The light-curing unit was calibrated at 1,200 nW/cm 2 and irradiance was measured using a radiometer. All specimens were stored in distilled water at 37°C for 24 h prior to testing. For the linear CTE, the samples measured 10 mm in diameter and 4 mm in thickness.

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.
