This was done using a 5th generation bonding agent, so total etch was done, starting with the enamel (10 sec) then dentin (10 more sec). Can also be done with self etching primers where only the enamel would be etched with phosphoric acid. Music Provided by FreeSongsToUse Dawns - Hero - Robin Hustin - Feelings - - Rolipso - Sway -
