Objectives
Narrative objectives1
The purpose of this study is to establish an objective method for longitudinal monitoring of root caries by evaluating the usefulness of demineralization values and images obtained with an optical diagnostic device for detecting root caries and assessing lesion activity, arrest, and progression.

Assessment
Primary outcomes
Association between demineralization values and image findings obtained by the optical diagnostic device and the clinical assessment of root caries activity at baseline and follow-up
Key secondary outcomes
Association between optical diagnostic measurements and visual findings for detecting root caries
Discriminative ability between active and arrested lesions
Longitudinal changes in demineralization values
Intra-examiner and inter-examiner reproducibility
Association between lesion progression during follow-up and optical findings
