Use of an Electronic Patient Record system to evaluate restorative treatment following root canal therapy

Electronic Patient Record (EPR) systems are rapidly gaining acceptance as an important tool for managing patient information. The purpose of this project was to evaluate the use of an EPR system for assessment of quality of care in an academic dental institution. The primary outcome of interest was the timeliness and completeness of restorative care following completion of nonsurgical root canal therapy. An initial query of the EPR database was performed using the following inclusion criteria: root canal treatment performed in the postgraduate endodontics clinic between September 2002 and June 2004, patient age > or =18 years old, and posterior tooth (premolars and molars). A total of 925 patients with 1,014 endodontically treated teeth met the inclusion criteria. A random sample of 30 percent of the treated teeth (302 teeth on 281 patients) was selected for detailed review. This sample of 302 teeth was then screened to determine if any restorative treatment had been performed between September 2002 and November 2005. Forty-eight percent (n=146) of the 302 teeth did not receive any form of permanent restoration over the time period studied. Twenty-five percent (n=75) of the teeth received a buildup only, and 27 percent (n=82) received the recommended treatment, a full occlusal coverage restoration. This study documents the use of an EPR system to objectively and efficiently assess one aspect of quality of care in a dental school environment.
