Study 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
Read the 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.

What researchers measure

Primary outcomes

  1. Mean of values measured by Diagnodent(TM) (fluorescence measurement device for carious lesions) for each study group

    Diagnodent values for fissure caries: 0-5: no demineralization, sound. 6-14: outer enamel demineralization. 15-20: inner enamel demineralization. 21-99: dentine demineralization.

    Time frame: Day 180

Secondary outcomes

  1. Mean of values measured by Diagnodent(TM) (fluorescence measurement device for carious lesions) for each study group

    Diagnodent values for fissure caries: 0-5: no demineralization, sound. 6-14: outer enamel demineralization. 15-20: inner enamel demineralization. 21-99: dentine demineralization.

    Time frame: Day 90 and Day 360

  2. Frequency of change in ICDAS-II (International caries detection and assessment system) codes for each study group

    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).

    Time frame: Day 90, Day 180, Day 360

  3. Frequency of change in caries lesion activity and severity assessed by Nyvad criteria for each study group

    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.

    Time frame: Day 90, Day 180, Day 360

  4. Mean of VAS values (Visual analogue scale) for each study group

    Range: from -50 (strongly remineralizing) to +50 (stronlgy progressing)

    Time frame: Day 90, Day 180, Day 360

  5. Frequency of Evaluation Outcome of Global Impression of Change Questionnaire for each study group

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

    Time frame: Day 90, Day 180, Day 360
