- Brief Summary
The purpose of this study is to evaluate
1. the additional therapeutic benefit of Curodont Repair for the treatment early occlusal carious lesions on permanent teeth in children compared fluoride varnish alone
2. the tooth gel Curodont Protect when using it after Curodont Repair instead of fluoride varnish
- Detailed Description
Objectives: The purpose of this study is to evaluate
1. the additional therapeutic benefit of Curodont Repair for the treatment early occlusal carious lesions on permanent teeth in children compared fluoride varnish alone
2. the tooth gel Curodont Protect when using it after Curodont Repair instead of fluoride varnish
Methods: 90 patients with early occlusal lesions (ICDAS-II:2-3) on permanent molars and pre-molars will be allocated in this randomized, controlled, single blinded study to one of the two test groups (Test1: Curodont™ Repair+Fluoride Varnish; Test2: Curodont Repair+Curodont Protect) or control (Fluoride Varnish) group.
Lesions will be assessed at baseline and recalls after 3, 6 and 12 months regarding caries activity (Nyvad), clinical status (ICDAS-II) and with Diagnodent®. Visual Analog Scale (VAS) in addition to the Global Impression of Change Questionnaire will also be used for the evaluation of the outcome.

Group Intervention Description Control Fluoride Varnish Fluoride Varnish (Fluor Protector S; Ivoclar, 7'700 ppm F-) application at Day 0 and Day180. =\> Group: Fluoride Varnish Test1 Fluoride Varnish Single application of Curodont Repair (P11-4) at Day 0 followed by a Fluoride Varnish (Fluor Protector S; Ivoclar, 7'700 ppm F-) application. Another fluoride Varnish application at Day180. =\> Group: Curodont Repair + Fluoride Varnish Test2 Curodont Protect Single application of Curodont Repair (P11-4) at Day 0. Curodont Protect (tooth gel containing P11-4 matrix) is handed out and subjects are asked to apply it 2x weekly at home after regular teeth cleaning in the evening for the whole study period (Day 360). =\> Group: Curodont Repair + Curodont Protect Test1 Curodont Repair Single application of Curodont Repair (P11-4) at Day 0 followed by a Fluoride Varnish (Fluor Protector S; Ivoclar, 7'700 ppm F-) application.

- Primary Outcome Measures
Name Time Method Mean of values measured by Diagnodent(TM) (fluorescence measurement device for carious lesions) for each study group Day 180 Diagnodent values for fissure caries:
0-5: no demineralization, sound. 6-14: outer enamel demineralization. 15-20: inner enamel demineralization. 21-99: dentine demineralization.
- Secondary Outcome Measures
Name Time Method Mean of VAS values (Visual analogue scale) for each study group Day 90, Day 180, Day 360 Range: from -50 (strongly remineralizing) to +50 (stronlgy progressing)
Mean of values measured by Diagnodent(TM) (fluorescence measurement device for carious lesions) for each study group Day 90 and Day 360 Diagnodent values for fissure caries:
0-5: no demineralization, sound. 6-14: outer enamel demineralization. 15-20: inner enamel demineralization. 21-99: dentine demineralization.Frequency of change in ICDAS-II (International caries detection and assessment system) codes for each study group Day 90, Day 180, Day 360 Code 0: Sound tooth surface, no evidence of caries after prolonged air drying (5 sec).
Code 1: First visual change in enamel. Code 2: Distinct visual change in enamel. Code 3: Localized enamel breakdown due to caries with no visible dentine or underlying shadow.
Code 4: Underlying dark shadow from dentine with or without enamel breakdown. Code 5: Distinct cavity with visible dentine. Code 6: Extensive distinct cavity with visible dentine (involving more than half of the dentine).Frequency of change in caries lesion activity and severity assessed by Nyvad criteria for each study group Day 90, Day 180, Day 360 Score 0: Sound. Score 1: Active caries - intact surface. Score 2: Active caries - surface discontinuity. Score 3: Active caries - cavity. Score 4: Inactive caries - intact surface. Score 5: Inactive caries - surface discontinuity. Score 6: Inactive caries - cavity.
Frequency of Evaluation Outcome of Global Impression of Change Questionnaire for each study group Day 90, Day 180, Day 360 Investigator Questionnaire: evaluation ranging from "very much worse" to "very much better"; 7-point scale
