Study Population

Practitioner investigators must have been enrolled in the DPBRN, completed the "Assessment of caries diagnosis \& caries treatment" study; and do at least some restorative dentistry in their practices. The human subjects directly involved in this study were patients who had sought treatment in the DPBRN practitioners' practices.

You may qualify if:

  • participants directly involved in this study were patients who sought dental treatment in the practitioner-investigators' practices
  • any tooth surface that was previously unrestored was eligible for this study, provided that it was on a permanent ("adult") tooth. This means that permanent first molars were eligible, which typically erupt at about age 6 years. This means that persons age 6 and older were enrolled in the study and there was no upper age limit.
