Device Story

CLEARFIL DC BOND is a dual-cure, two-component, one-step dental adhesive system. It is composed of dimethacrylate monomers. The device is applied by a dental professional to dentin, enamel, and metal surfaces to promote adhesion of restorative materials. It functions as a bonding agent for direct restorations, core build-ups, cavity sealing, root surface treatment, and intraoral repairs of fractured dental prosthetics. The dual-cure capability allows for both light-cure and self-cure polymerization, providing flexibility in clinical application. By facilitating the bond between tooth structure and restorative materials, it aids in the structural restoration of teeth.

Clinical Evidence

Bench testing only. Performance was evaluated through tensile bond strength testing and marginal sealing (microleakage) tests comparing the subject device to the predicate devices.

Technological Characteristics

Two-component, one-step, dual-cure (light- and self-cure) resin-based dental adhesive system. Composition includes dimethacrylate monomers. No specific ASTM standards or software/connectivity features are described.

Indications for Use

Indicated for dental patients requiring core build-ups, direct restorations (light- or self-cure), cavity sealing for indirect restorations, treatment of exposed root surfaces, and intraoral repair of fractured crowns/bridges (porcelain, ceramic, hybrid, or composite).

Regulatory Classification

Identification

A resin tooth bonding agent is a device material, such as methylmethacrylate, intended to be painted on the interior of a prepared cavity of a tooth to improve retention of a restoration, such as a filling.
