An In Vitro Evaluation of Leakage of Two Etch and Rinse and Two Self-Etch Adhesives after Thermocycling

Table 1

The different tested adhesive systems and their components.

Adhesive systems
Name of the adhesive	Type of adhesives	Components
SBMP	ER, 3 steps	Phosphoric acid (35%)
		Primer = HEMA, polyalkenoic acid copolymer, water
		Bonding = HEMA, Bis-GMA, amines, photoinitiator
SB1	ER, 2 steps	Phosphoric acid (35%)
		Adhesive (primer + bonding) = dimethacrylates, HEMA, polyalkenoic acid copolymer, silanized silicium, alcohol, water, photo-initiator
ADSE	SE, 2 steps	Primer = dimethacrylate, phosphonic acid acrylate, initiators, stabilizers
		Bonding = HEMA, dimethacrylate, silicon dioxide, Initiators, stabilizers
ADSE-1	SE, 1 step	Derivates of bis-acrylamide, water, alcohol, bis-methacrylamide dihydrogen phosphate, amino acid acrylamide, hydroxyl alkyl methacrylamide, alkyl sulfonic acid acrylamide, highly dispersed silicon dioxide, initiators, stabilizers, and potassium fluoride

In this table, the tested adhesives are displayed according to the adhesion’s strategy and the type of adhesives: Etch and Rinse (ER) adhesive systems (SBMP and SB1) and Self-Etch adhesive systems (ADSE, ADSE-1). SBMP: Scotchbond Multipurpose Plus (3 M ESPE AG, Dental products, Seefeld, Germany). SB1: Adper Scotchbond 1 XT (3 M Espe AG, Dental products, Seefeld, Germany). ADSE = AdheSE (Ivoclar Vivadent AG, Schaan, Liechtenstein). ADSE-1: AdheSE One (Ivoclar Vivadent AG, Schaan, Liechtenstein).
