Effect of Curodont Repair in Patients With Early Approximal Carious Lesions

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to evaluate the therapeutic benefit of Curodont Repair for the treatment of early approximal carious lesions compared to no treatment.

Detailed Description
-----------------
All study participants must have two early approximal 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 the other will not undergo a treatment as control. Study duration is 12 months. For assessment x-ray pictures are used.
