Professor Moritz, president of ESOLA, gave a mind opening presentation on Bond strengths with regard to one step bonding agents.  Bottom line is that if the laser was used prior to application of one step agents, bond strengths were reasonable because the laser removed the smear layer and opened the tubules. Otherwise bond strengths were extremely poor…These were verified by some of the best sems I have ever seen….So Bonders beware..
He also showed some unbelieevable sems with regard to bleaching material and damage to the enamel…Bottom line there is that  many products including whitestrips damage enamel and what has been shown with a new bleaching agent not on the market yet is that rapid laser light application ( Diode, or ND yag) in conjuction with the gel produced good results with little to no enamel surface alteration……So stay tuned cause bleaching the way we know it is going to change.
