Study Overview
Brief Summary
The aim of this randomized controlled, double-blinded, split-mouth clinical trial was to evaluate the efficacy of self-assembling peptide P11-4 solution (Curodont™ Repair) with fluoride varnish on the progression of non-cavitated proximal caries compared to casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) with fluoride varnish (MI Varnish™) sodium fluoride (NaF) varnish (Profluorid® Varnish).
The study included 300 permanent molars belonging to 150 children, aged between 7 to 13 years old, who had two non-cavitated proximal carious lesions.
Detailed Description
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.

Outcomes
Primary Outcomes
The assessment of lesion progression by digital subtraction radiography (DSR)
Time Frame: 12 months after the clinical applications
The primary outcome of the study was assessment of lesion progression (change in the lesions' opacity) by DSR readings, at 12th month.
Secondary Outcomes
- The assessment of lesion progression by independent visual reading of radiographs(12 months after the clinical applications)
- The assessment of lesion progression by pair-wise visual reading of radiographs(12 months after the clinical applications)
