Thirty-two enamel slabs (8×8×2 mm3) were cut, and flattened using sequential water-cooled abrasive discs (500-, 1200-, 2400- and 4000-grit Al2O3 papers; MD-Fuga, Struers Inc, Cleveland, OH, USA), polished (1-μm diamond suspension, Struers Inc) and sonicated for 3-min in detergent solution. Specimens with any cracks or structure defects were discarded. They were incubated in 2 ml/specimen of whole saliva supernatant for 24 h at room temperature under gentle agitation (85–90 RPM) for AEP formation. Then, all specimens were subjected to 2-min treatments with 4 ml/specimen of the tested rinses, dried with absorbent paper, and immersed in whole saliva supernatant (2 ml/specimen) for 2 h, at room temperature. This cycle was repeated three times.

Enamel and dentin slabs (4 × 4 × 2 mm) were obtained from bovine incisors, using a microtome (Isomet, Buehler, Lake Bluff, IL, USA). The specimens were embedded in acrylic resin (Varidur, Buehler), and the resulting blocks were ground flat and polished with Al2O3 papers grit #500, 1200, 2400, and 4000 (MD-Fuga, Struers Inc, Cleveland, OH, USA), under water cooling, and polishing cloth and diamond suspension (1 μm; Struers Inc.). At the end of the polishing procedures, the specimens were sonicated in distilled water for 3 min. The specimens with cracks or any other surface defects were discarded. Unplasticized polyvinyl chloride tapes were then placed on the polished surfaces of the selected specimens, leaving a central window of 4 × 1 mm exposed.

Forty bovine root dentin slabs (4'4'2 mm 3 ) were cut from bovine incisors using a microtome (Isomet Buehler, Lake Bluff, USA). They were embedded in acrylic resin blocks (10×10×8 mm 3 ) (Varidur Buehler, Lake Bluff, USA), flattened using sequential water-cooled abrasive discs 500-, 1,200-, 2,400-and 4,000-grit Al 2 O 3 papers; MD-Fuga, (Struers Inc., Cleveland, USA), polished 1-µm diamond suspension (Struers Inc., Cleveland, USA) and sonicated in a detergent solution (Micro-90, International Products Corporation, Burlington, USA). Specimens with any visual cracks or defects were discarded. Adhesive TC414 unplasticized polyvinyl chloride tape (TapeCase Ltd., Wheeling, USA) was placed on the specimens to create reference surfaces, leaving a central surface area of 4'1 mm 2 in the dentin exposed to the cycling procedure. The specimens were then randomly assigned to three test groups (SnCl 2, NaF, or both) and one control group (DIW) (n = 10).

Fifty-five enamel and 55 root dentin specimens (4 x 4 x 2 mm) were obtained from included human third molars, selected for not being in contact with the oral cavity. The crowns and the roots were sectioned in the microtome, and the specimens obtained were embedded in acrylic resin (Varidur; Buehler, Lake Bluff, IL, USA), ground flat with water-cooled abrasive discs 500-, 1200-, 2400-and 4000-grit carbide papers, (MD-Fuga; Struers Inc., Cleveland, OH, USA), and polished in polishing pads with diamond-particle dispersion (1 µm, Struers Inc.). The polished surfaces were covered with an adhesive tape (control area), leaving a central test area of 4 x 1 mm exposed to the erosive challenge.
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.
