Brief summary
This retrospective study aims 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.
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). Restorations were assessed clinically according to the USPHS criteria by two independent evaluators using mirrors and probes. Data will be analyzed using Chisquare, Mann-Whitney and Wilcoxon tests at a 0.05 level of significance.
Interventions
OTHERRetrospective evaluation of amalgam and composite restorations
Multi-surface restorations that were performed by dental students and that are in function for the last five years will be clinically evaluated with mirrors and probes according to the modified USPHS criteria.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative sensitivity | 5 years | No Patient-reported sensitivity to hot and cold stimuli, sweets, clenching, and chewing related to the restoration (Alpha) |
| Secondary caries | 5 years | No visual evidence of dark, deep discoloration adjacent to the restoration (Alpha) |
| Proximal contact | 5 years | No open contact. Contact offers resistance to the dental floss (Alpha) |
| Marginal Adaptation | 5 years | Restoration closely adapted to the tooth. No crevice visible (Alpha) |
| Fracture restoration | 5 years | No evidence of fracture (Alpha) |
| Fracture tooth | 5 years | No evidence of fracture (Alpha) |
| Anatomy | 5 years | Restorations continuous with existing anatomic form (Alpha) |
