Clinical Trial 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.


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.

Intervention

Device:
Curodont™ Repair
It is a product used in biomimetic remineralization of initial carious lesions. The product consists of "smart" P11-4 peptide molecules (CUROLOX® TECHNOLOGY) that within the lesion the molecules self-assemble to a 3D matrix. This bio-matrix enables the regeneration of the tooth tissue. Test 1 lesions will be cleaned with a prophylaxis paste and isolated with cotton rolls. Then, the pellicle will be removed using 2% sodium hypochlorite (20 sec) and the inorganic deposits will be removed using 35% phosphoric acid (20 sec). The tooth surface will be rinsed with water and dried. Thereafter, Curodont™ Repair will be applied in compliance with the manufacturers' instructions and left for 5 minutes.
MI Varnish™
MI Varnish™ is a 5% sodium fluoride (NaF) varnish that has a desensitizing action when applied to tooth surfaces. The product also contains RECALDENT™ (CPP-ACP): Casein Phosphopeptide-Amorphous Calcium Phosphate. The application leaves a film of varnish on tooth surfaces and also facilitates the tooth remineralization. Test 2 lesions will be isolated with cotton rolls. Then, MI Varnish ™ will be applied as a thin layer in equal thickness with a disposable brush in accordance with the manufacturers' instructions. Thereafter, the tooth surface will be moistened with water or saliva to ensure that the material adheres to the applied area.
Profluorid® Varnish
Profluorid® Varnish is a 5% sodium fluoride (NaF) varnish for surface application to enamel and dentin. The product will adhere to wet surfaces and is tolerant to moisture and saliva. Profluorid® Varnish is an ethanolic suspension of colophony with artificial flavors and sweetened with xylitol. It is also used in the remineralization of initial caries. Control lesions will be isolated with cotton rolls. Then, Profluorid® Varnish will be applied as a thin layer in equal thickness with a disposable brush in accordance with the manufacturers' instructions. Thereafter, the tooth surface will be moistened with water or saliva to ensure that the material adheres to the applied area.

Outcome

Type Measure Description Time frame Safety issue
Primary The assessment of lesion progression by digital subtraction radiography (DSR) The primary outcome of the study was assessment of lesion progression (change in the lesions' opacity) by DSR readings, at 12th month. 12 months after the clinical applications
Secondary The assessment of lesion progression by pair-wise visual reading of radiographs One of the secondary outcomes of the study was assessment of lesion progression (change in the lesions' opacity) assessed by pair-wise visual readings, at 12th month. 12 months after the clinical applications
Secondary The assessment of lesion progression by independent visual reading of radiographs The other one of the secondary outcomes of the study was assessment lesion progression (change in the classification of the lesions' size with respect to E0-E2, D1-D3 radiographic scoring system) assessed by independent visual readings, at 12th month. 12 months after the clinical applications
