Effect of Self-Assembling Peptides on the Progression of Non-Cavitated Proximal Caries

First, the subjects were randomly allocated to three main groups with 50 individuals in each. Then the carious lesions belonging to each subject were randomly assigned to two subgroups based on different treatment agents used: Group 1; P11-4+NaF/NaF, Group 2; P11-4+NaF/CPP-ACP+NaF, Group 3; CPP-ACP+NaF/NaF. Accordingly, test 1 lesions received P11-4+NaF combination, test 2 lesions received CPP-ACP+NaF varnish, and control lesions received NaF varnish alone. At the 6th and 12th months after the clinical applications, Profluorid® Varnish application was repeated for test 1 and control lesions, and MI Varnish™ application was repeated for test 2 lesions. At the end of the 12 months, carious lesion progression status was evaluated radiographically, by using independent visual reading, pair-wise visual reading, and digital subtraction radiography (DSR) methods.
