Objective: The clinical acceptance of restorative material normally depends on its biological safety. This in vivo study considered the clinical and histological gingival response to methacrylate and silorane‑based composites. Materials and Methods: Sixty patients with sub‑gingival tooth defects were treated in two groups (n = 30) with Tetric N‑Ceram and Filtek P90 composite restoratives with minimal finishing procedures. An additional 10 patients with pre‑existing gingival inflammation and no cervical tooth defects served as control. The gingiva in contact was assessed clinically and histologically at 2, 4 and 8 week intervals. Results: A significant time‑dependent gingival response was noted in both test groups (t‑test, P < 0.05). Inflammatory cell infiltrates, cellular degeneration, epithelial hyperplasia, keratinization, and erosion were found in selected gingival biopsies. Conclusion: The results confirmed that minimally finished subgingival composite restorations contribute to significant histopathological changes to the contacting gingival tissues. However, the silorane‑based composite elicited less severe gingival inflammatory symptoms in comparison to the methacrylate‑based resin system.
