Objectives: Occlusal surfaces of erupting permanent molars are highly prone to caries. Self-assembling peptide (P11-4) has proven to enhance biomimetic mineralization of early carious lesions. Aim of this study was to evaluate safety, clinical applicability and effect of using P11-4 (Curodont™ Repair) in non-invasive treatment of early occlusal lesions. Methods: 70 patients with active early occlusal lesions (ICDAS-II:1-3) on first or second permanent molars at eruption will be allocated in this randomized, controlled, single blinded study to test (Curodont™ Repair+Duraphat®) or control (Duraphat®) groups.

Safety and applicability will be evaluated using dentist's/patient's questionnaires about adverse events, difficulties of application and satisfaction with procedure. Lesions will be assessed at baseline and recalls after 3 and 6 months regarding caries activity, clinical status (ICDAS-II) and with Diagnodent®. The Visual Analog Scale (VAS) of regression and of lesion size in addition to the Global Impression of Change Questionnaire will also be assessed. At every recall, fluoride varnish will be applied on lesions and patients received oral health instructions.

Caries Activity and Progression Assessment Using LASER Fluorescence Readings by Diagnodent® Device.
Evaluation of the additional therapeutic benefit of Curodont™ compared to fluoride varnish (Duraphat®) alone on early occlusal carious lesions using LASER "Light Amplification by Stimulated Emission of Radiation" fluorescence readings by Diagnodent® device. Diagnodent® device measures the caries activity using LASER fluorescence of bacterial secretions in the caries lesion. The readings range from 0 to 99; 0 means no bacterial activity in the carious lesion whereas 99 refers to high bacterial and caries activity. Effect via the changes in LASER fluorescence readings between Baseline and 6-months recall (Change = Baseline value - 6 months value). Higher positive change value means caries regression, whereas lower positive or negative change value refers to caries progression.
Time frame: 6 months
Visual Analog Scale of Lesion Progression (VAS)
Visual Analog Scale of lesion progression (VAS), Effect via t test between Baseline and 6-months recall VAS values range from -100 % to +100 %. The value of -100 means that the carious lesion is strongly remineralising, the value of 0 means that the lesion is arrested, and the value of +100 means that the lesion is strongly progressing.
Time frame: 6 months
ICDAS Classification Index
Number of patients who have improvement on the ICDAS classification index (International Caries Detection and Assessment System), changes from Baseline to 6-months recall. This carries clinical index range from 0 to 6. The values mean: 0 No evidence of caries 1. Initial caries 2. Distinct visual change in enamel 3. Localised enamel breakdown due to caries with no visible dentine 4. Underlying dark shadow from dentine 5. Distinct cavity with visible dentine 6. Extensive distinct cavity with visible dentine. During the study, a change from level to lower level number (e.g. from 2 to 1) in patients means that the carious lesion is regressed.
Time frame: 6 months
Caries Activity Assessment According to Nyvad Criteria
Caries activity assessment according to Nyvad criteria, number of participants still have active lesions overall study. This assessment includes two clinical judgment inserts: active lesion or inactive lesion basing on visual-tactile surface characteristics of the caries lesions such as integrity, texture, translucency/opacity, lesion location, and surface color. During the study, an alteration from active lesion to in active lesion means an improvement.
Time frame: 6 months
