Effective 10-MDP Bonding to Saliva-Contaminated Dentin.

Purpose: The study aimed to measure the efficacy of 10-methacryloyloxydecyl dihydrogen phosphate (10-MDP) saliva-decontamination protocols by measuring bonding effectiveness to saliva-contaminated dentin following different surface-decontamination protocols.

Materials And Methods: The micro-tensile bond strength (µTBS) of the two-step self-etch (SE) adhesive Clearfil SE Bond 2 ('CSE2', Kuraray Noritake) and the one-step SE adhesive Clearfil Universal Bond Quick ('CUBQ', Kuraray Noritake) to saliva-contaminated bur-cut dentin was measured when saliva-contaminated dentin was decontaminated by either the 10-MDP-containing Katana Cleaner ('KC', Kuraray Noritake) or CSE2 primer ('CSE2p'), with bonding to saliva-contaminated ('saliva(-)') and non-contaminated dentin ('clean(+)') having served as negative and positive control, respectively. Half of the specimens were subjected to µTBS testing 'immediately' after 1-week water storage, while the other 'aged' half was tested after 50,000 thermocycles.
