Study Description
Brief Summary:
The purpose of this study will allow us to observe and follow the subjects' treatment from DPBRN Prevalence of Questionable Occlusal Caries Lesions Study over a 24 month period.

Condition or disease
Dental Caries

Detailed Description:
There have been very few studies regarding questionable lesions, virtually no clinical evaluations of the progression of questionable lesions over time, and no studies depicting the prevalence of these lesions. Since carious lesions have the ability to arrest and possibly reverse, determining how often these lesions are being seen in practice and learning more about their characteristics and patient risk assessment are important steps in order to manage these lesions without unnecessary surgical intervention.
