简要总结

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.

详细描述

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.

Marginal Adaptation

时间窗: 5 years

Restoration closely adapted to the tooth. No crevice visible (Alpha)

Anatomy

时间窗: 5 years

Restorations continuous with existing anatomic form (Alpha)

Postoperative sensitivity

时间窗: 5 years

No Patient-reported sensitivity to hot and cold stimuli, sweets, clenching, and chewing related to the restoration (Alpha)

Secondary caries

时间窗: 5 years

No visual evidence of dark, deep discoloration adjacent to the restoration (Alpha)

Fracture restoration

时间窗: 5 years
