Detailed description

Purpose: The aim of this retrospective study is to evaluate the clinical performance of posterior multi-surface Class II amalgam (AM) and resin composite (RC) restorations placed by dental students over a five-year period. Materials and Methods: A total of 119 multi-surface Class II restorations (three or more surfaces) placed by third and fourth year students will be evaluated (AM: n = 69 and RC: n = 50).
