Enamel Microhardness Standardization

Twenty bovine teeth were cut with a double-faced diamond disc (KG Sorensen, Barueri, SP, Brazil) under water-cooling, to obtain 40 dental blocks (5 × 5 mm, from the buccal surface of the teeth) and they were used for microhardness test. Blocks were embedded in acrylic resin (Jet-Classic, Cremer, Blumenau, SC, Brazil), leaving the buccal surface exposed. After the complete acrylic resin polymerization (approximately 1 h), the blocks were planed and polished with silicon carbide sandpaper (Carbinet, Buehler, Lake Bluff, IL, USA) with decreasing grain (#400, #600, #1200, and #4000) for 30 seconds in each sandpaper [13 (link), 29 (link)] to standardize the amount of enamel to be removed.
Finally, 1 μm grain diamond paste (Buehler, Lake Bluff, IL, USA) applied with a felt disc (Texmet 1500, Buehler, Lake Bluff, IL, USA) was used for another 30 sec.

The specimen surfaces were then polished using silicon carbide abrasive papers (#1000-, 1500-, and 2000grit size, Wetordry Tri-M-ite sheet, 3M, St. Paul, MN, USA) under continuous water cooling. Mirror finish was obtained for the specimens using monocrystalline diamond suspensions (3 µm and 1 µm, MetaDi, Buehler) and a non-woven pressed cloth (TexMet 1500, Buehler). After polishing, the specimens were cleaned in ultrasonic bath for 10 min in distilled water and were stored at 37ºC in water for 24 h.

Four CAD/CAM composite blocks for molars, one CAD/CAM composite block for premolars, and one CAD/CAM feldspathic ceramic were used in this study. The product names, manufacturers, abbreviations, and compositions are shown in Table 1. A diamond disk (IsoMet, Buehler, Lake Bluff, IL, USA) was used to create seven plate-shaped specimens (thickness, 2.5 mm) from each block. All specimens were wet-ground with a series of silicon carbide papers, after which they underwent mirror finishing with a diamond suspension (3 μm and 1 μm, MetaDi, Buehler) and wet felt cloth (TexMet 1500, Buehler). After polishing, specimens underwent ultrasonic cleaning for 10 min in distilled water and were stored at 37ºC in water for 24 h.

Bonding Interface Characterization Protocol

A thin layer of MMA-TBB resin was applied directly to the primed surface. After storage in purified water for 24 h at 37°C, the bonded specimens were sectioned perpendicularly to the resin/enamel interface, using a low-speed saw (IsoMET, Buehler) under water coolant. The sectioned specimens were ground with a series of polishing papers (WetorDry Tri-M-ite Sheet, 800-, 1000-, 1200-, 1500-, and 2000-grit, 3M) under running purified water and polished using a non-woven pad (TexMet 1500, Buehler) and monocrystalline diamond suspensions (MetaDi, 3 and 1 μm, Buehler). The smeared layer and diamond suspensions were removed ultrasonically for 5 min in purified water. The polishing surfaces were etched with 10% orthophosphoric acid (P1745, Tokyo Chemical Industry Co., Ltd.) for 15 s. The sectioned surfaces of the two bonded groups were etched with 6 mol/L hydrochloric acid (HCl, Wako Pure Chemical Industries Ltd., Tokyo, Japan) for 25 s. The specimens were then washed with purified water and dried for 24 h in a desiccator, after which they were sputter-coated with osmium for 60 s (Osmium Coater HPC-1SW, Vacuum Device Co., Ltd., Mito, Japan) and observed with a scanning electron microscope (SEM, S-4300, Hitachi High-Technologies Corp., Tokyo, Japan) operated at an accelerating voltage of 15 kV.

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.
