Purpose: This study evaluated the materials used for tooth core restorations
by dental students. Materials and Methods: The study included all patients
treated with a single crown or fixed partial denture by undergraduate dental
students during the years 1984 to 1986, 1994 to 1996, and 2004 to 2006.
Results: More direct (62%) than indirect (38%) cores were prepared during the
total time period evaluated. Conclusion: The complication rate of indirect cores
compared with direct ones appeared to be higher in single crowns, but not in
fixed partial dentures. Int J Prosthodont 2014;27:73–75. doi: 10.11607/ijp.3609
