Reasons for Placing the First Restoration on Permanent Tooth Surfaces
This study of previously-untreated permanent tooth surfaces was the second of the restorative dentistry studies planned for the Dental Practice-Based Research Network (DPBRN). The aims for this study were to: (a) quantify DPBRN practitioner-investigators’ pre-operative and post-operative assessments of the depth of the caries lesion being treated and (b) quantify the prevalence of dental material types used to restore the first restoration in a permanent tooth surface. These aims were met by enrolling 229 DPBRN practitioner-investigators in this study, each of whom recorded information about an average of 50 consecutive restorations that they placed on unrestored permanent tooth surfaces. The study recorded the main reason that the restoration was placed, the preoperative and postoperative depth of the caries lesion on the previously unrestored surface, and the type of dental restorative material that was used. This study about restorative treatment received by DPBRN patients provided the opportunity to record not only the diversity in the treatment provided, but also to generate information for subsequent hypothesis testing and for the design of future studies.
