Postoperative Hypersensitivity and Its Relationship to Preparation Variables in Class I Resin - Based Composite Restorations : Findings from the Practitioners Engaged in Applied Research and Learning ( PEARL ) Network : Part 1

The New York University Practitioners Engaged in Applied Research and Learning (PEARL) Network and The EMMES Corporation, the network’s data coordinating center, comprise a National Institute of Dental and Craniofacial Research-supported practice-based research network (PBRN). The PEARL Network recently completed a study on postoperative hypersensitivity in resin-based composite (RBC) occlusal restorations, which included patient-reported baseline findings and 1-week, 4-week, and 13-week outcomes. Interim results of this study have been published.1,2 In the present report, the authors address the sensitivity findings related to preparation variables associated with restoration and patient demographics.
