Abstract Objectives This study evaluated the adhesion and whitening effects of a combination P11-4 self-assembling peptide hydroxyapatite (peptide-HAP) on bovine enamel. Methods Forty-six caries-free teeth were selected, 40 randomly allocated to one five groups ( n = 8). First, application frequency, exposure time, storage in saliva an experimental low-concentrated peptide-HAP suspension (0.5 wt% HAP; Curodont, Credentis) compared with commercial bleaching agent (VivaStyle Paint Plus, VS, Ivoclar Vivadent). Tooth color was measured using spectrophotometer (Gretag MacBeth), changes ΔE statistically analyzed. Second, concentration (low versus high: 6.25% Curodont Protect), its interactions postapplication restaining, investigated. Third, enamel surfaces 2) treated low high-concentration polymeric monomeric forms (Curodont Protect & Repair, analyzed by SEM. Results The Δ E low-concentration did not differ from that VS. Application have any significant impact efficacy suspension. Increasing promote overall . SEM observations confirmed presence newly generated HAP surface. Conclusions is mild tooth whitener, dependent. Clinical relevance effective offsetting discoloration caused restaining after treatment.
