Effect of Curodont Repair or Placebo on the Remineralisation in Patients With Class 5 Carious Lesions

Not Applicable

Completed

• Conditions: Dental Caries
• Interventions: Other: Placebo; Device: Curodont Repair; Device: Fluoride

• Registration Number: NCT02020681
• Lead Sponsor: Credentis AG

Brief Summary

The purpose of this study is to evaluate the therapeutic benefit of Curodont Repair for the treatment of early buccal carious lesions compared to placebo.

Detailed Description

All study participants must have two early class V carious lesions in need of a treatment but not of an invasive treatment (split-mouth design). One lesion will be treated with Curodont Repair and one with placebo as control (single application). 3 months later fluoride (Duraphat) will be applied on both lesions. Study duration is 9 months. For assessment visual and tactile evaluation, pictures, ECM, Diagnodent Pen, Canary System, VAS is used.

Primary Outcome Measures

Name	Time	Method
The primary efficacy outcome is the difference of the change in the lesion size assessed by morphometry (standardised pictures) between investigational medical device and placebo group.	D0, D30, D90, D270	Change of lesion size relative to baseline between study groups and different time points

Secondary Outcome Measures

Name	Time	Method
Difference in the change of Diagnodent Pen values between investigational medical device and placebo group.	D0, D30, D90, D180, D270	only descriptively analysed
Change in lesion's progression assessed by VAS between investigational medical device and placebo group.	D0, D30, D90, D180, D270	only descriptively analysed
