MONCADA, Gustavo et al. The Role of 10-methacryloyloxydecyl dihydrogen phosphate in the paradigm of change to adhesive systems integrated to dentin. Rev. Clin. Periodoncia Implantol. Rehabil. Oral [online]. 2014, vol.7, n.3, pp.194-199. ISSN 0719-0107.  http://dx.doi.org/10.1016/j.piro.2014.09.008.

Applying self-etching dental adhesives containing 10-MDP overcomes the resistance to biodegradation of the adhesive interface of traditional total etch. The mechanism of action is based on the formation of multiple nano-layers of calcium and two molecules of 10-MDP on the dentin surface. These multiple layers of 3.5 nm protect the collagen fibers from hydrolysis phenomenon. The nano-layer explains its high stability and bond strength over time, tested both by clinical and laboratory studies. Hydroxyapatite interaction occurs with acids of low pH, but are higher than traditional, thus increasing the need to recommend the previous selective etching of the enamel. The use of MDP allows a change of philosophy from the total-etch adhesive to adhesive integration of the dentin.
