Clearfil® SE Protect Bond

Clearfil® SE (Single Ended) Protect is a light-cure self-etching dental bonding agent. CLEARFIL SE Protect contains a patented***, specially treated sodium fluoride (NaF); the NaF in CLEARFIL SE Protect is coated with a unique polymer capsule that allows release of the NaF while the bonding layer physical properties, including strength, are maintained. CLEARFIL SE Protect makes an “acid-base resistant zone” (called Super Dentin) interface between the bond and dentin behind the hybrid layer (Fig. 3, SEM image), as a result of the fluoride release. Etch & rinse (total-etch) products like Adper Single Bond cannot make this zone3) 4). This zone is 1.2µm which is thicker than the hybrid layer and very important for resisting the acid generated by bacteria if microleakage does occure

The test results of tensile bond strength (Fig. 5) show that CLEARFIL SE Protect has clear advantages regarding bond strength and durability compared with 3- or 2-step total-etch (etch and rinse) bonding agents, such as Adper Scotchbond Multi-Purpose* (3-step) or Adper Single Bond* (2-step), and 1-step self-etch such as i Bond*. In addition, CLEARFIL SE Protect showed excellent clinical performance in high stress bearing areas for at least five years7).
