Abstract
Amphiliic lipids (L-alanine n-alky ester/p-toluensulfonic acid salts) prepared from n-alky alcohol and L-alanine were dissolved in MMA ranging in concentration from 0.5 mol% to 2.0 mol%. The enamel bonding and antibacterial sensitivity of resins, which were MMA liquid /PMMA powder mixtures cured by TBB, were investigated.
