Two components, two steps
Clearfil SE Bond is composed of two single liquids: a mild self-etching primer with a low technique sensitivity and a light-curing bonding agent with a high sealing ability. It is indicated for:
Bonding of direct restorations made of light-curing composite or compomer
Cavity sealing as a pretreatment for indirect restorations
Treatment of hypersensitive and/or exposed root surfaces
Intraoral repair of chipped or fractured restorations made of porcelain, hybrid ceramics or composite resin using light-curing composite
Surface treatment of prosthetic appliances made of porcelain, hybrid ceramics or cured composite resin
Durable marginal seal
Powerful hydrolysis resistance for a durable marginal seal: This is offered by Clearfil SE Bond thanks to three features:
- The MDP monomer forms a stable chemical bond between adhesive and tooth structure – resistant to hydrolysis.
- Mild self-etching ensures that the hydroxylapatite is not completely removed from the collagen fibers, protecting them from hydrolytic degradation.
- The bonding agent’s low water sorption further strengthens the marginal seal in the long term.
In this way, the risk of secondary caries is minimized.
Minimal post-operative sensitivities
In Clearfil SE Bond, the mild self-etching primer ensures that irritation caused by moving dentinal fluid is minimized. When the higher viscosity bonding agent is applied on top of the primer, a strong and stable bond layer is created. This layer excellently seals the dentinal tubules, so that occlusal stress caused by potential movement of dentinal fluid is prevented. The result: Minimal postoperative sensitivities.
With Clearfil SE Bond, neither a separate acid etching nor a rinsing step are necessary. Additionally, less attention to the surface moisture level has to begiven: The risk of over-wetting or over-drying of thepreparation is very low e.g. compared to wet bonding systems. This leads to a low technique sensitivity and simplified application requiring only a few steps:
MDP. What else?
Clearfil SE Bond 2 contains the Original MDP Monomer, an essential component of any adhesive product from Kuraray Noritake. Having been in use for more than 35 years, MDP offers a proven excellence in adhesion. The hydrophilic group of the adhesive monomer forms a strong chemical bond with calcium and hydroxylapatite. Since hydroxylapatite crystals remain in the hybrid layer after mild self-etching, a stable hybrid layer is formed by the adhesive. In addition, a strong bond to enamel is ensured.
