Evaluation of the Bond Strength of Self-Etching Adhesive Systems Containing HEMA and 10-MDP Monomers: Bond Strength of Adhesives Containing HEMA and 10-MDP

Table 1

Experimental groups (n = 16 per group).

Group	Adhesive	Composition	Classification	Application mode
G1 (control)	Prime and bond U Dentsply Sirona, Konstanz, Germany	Bis-acrylic diamine; water; propanol; dihydrogen phosphate methacrylate; penta; bis-acrylic propylamine; camphorquinone; hexafluorophosphate; dimethylamino benzonitrile; hydroquinone.	1 step	Apply keeping the surface completely wet; if necessary, apply twice. Shake lightly for 20 seconds. Apply a moderate blast of air for at least 5 seconds to keep the layer even. Ten- to twenty-second curing time
G2	OptiBond All-in-One Kerr, New South Wales, Australia	Acetone; 2-hydroxyethyl methacrylate; ethyl alcohol; 2002Dhydroxy-1,3-propanediyl bismethacrylate; silica; amorphous, fumed, cryst-free, methyl alcohol.	1 step	Active application of the first layer of adhesive for 20 seconds. Active application of the second layer of adhesive for 20 seconds. Dry with light blast and then medium blast for at least 5 seconds. Ten-second curing time.
G3	Clearfil SE Kuraray Medical Inc, Tokyo, Japan	Primer: MDPB; MDP; HEMA; hydrophilic dimethacrylate; photoinitiator; water Bond: MDP; HEMA; Bis-GMA; hydrophobic dimethacrylate; photoinitiators; silanates.	2 step	Active application of primer for 20 seconds. Short air blast for 5 seconds. Active application of bond for 15 seconds. Removal of excess with an air blast for 3 seconds. Ten-second curing time.
