The development of dental adhesive materials has recently been very significant. There is a justified requirement of clinical dentists to have reliable adhesive materials that ensure quality interconnection of different material surfaces during dental treatment. The introduction of functional monomers such as 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) is considered to be very effective and one of the most common functional monomers with the ability to bind to metal oxides as well as hard dental tissues. The long-term stability of the bond between 10-MDP and various other materials is still the subject of the research. The bonding mechanism of adhesive materials containing the MDP monomer is based on micromechanical and chemical bonding. The authors of this review article attempt to elucidate the exact functional mechanism of this monomer as for the adhesion to enamel, dentine and zirconium.

Conclusion: The 10-MDP is one of the most used functional monomers with ability to bind to both metal oxides and hard dental tissues. The dihydrogen phosphate group from the MDP molecule is responsible for chemical bonding to metal oxides and dental tissues, while the methacrylic group is inevitable for copolymerization of the 10-MDP molecule and the monomer matrix in the resin cement. The decyl group (with ten carbon atoms) prevents the penetration of water into the adhesive bond and thus disable any hydrolytic degradation of the bond. The long-term stability of the bond between 10-MDP and other materials is still the subject of the research, so the dentists may encounter with degradation of the resin and zirconium-ceramic bond over time.
