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.

Primary Outcome Measures
NameTimeMethod
Mean of values measured by Diagnodent(TM) (fluorescence measurement device for carious lesions) for each study groupDay 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
NameTimeMethod
Mean of VAS values (Visual analogue scale) for each study groupDay 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 groupDay 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 groupDay 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 groupDay 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 groupDay 90, Day 180, Day 360

Investigator Questionnaire: evaluation ranging from "very much worse" to "very much better"; 7-point scale
