Cytotoxic resin components of common dental bonding agents are known to cause oxidative damage and suppress odontogenic differentiation of dental pulp cells. [1-4] As antioxidants were found to protect cells from cytotoxicity of resin monomers in previous studies,[5-8] we investigated the effects of common antioxidants, such as !-carotene, resveratrol and Vitamin E on anti-differentiation activ...

The clinical success of adhesive composite-resin restorations has changed the way that dentists treatment plan and treat periodontally mobile teeth. While adhesive composite resin provides for strong, durable, and esthetic single-tooth restorations, when placed to join teeth together, these materials—which are chemically brittle by nature—are susceptible to fracture and are not durable. When su...
