Time dependent penetration of P11–4 into dentin tubules. a) Confocal microscopy of human dentin plate (scale bar 50 μm). b) Penetration of labeled self-assembling peptide P11–4 (1:10 mix with a 20 mg/ml concentration) in dentin tubuli was tracked by confocal microscopy after 4 days incubation (scale bar 50 μm). A deep penetration of P11–4 into dentin tubuli can be observed
