Practical How To Supporting Your Practice

Practical How To: How can you effectively bond to dentin using a self-etching bonding agent?


This post was prepared in collaboration with Kuraray

On an experimental basis, we have asked a limited number of companies to provide us with practical “How To” answers to clinical questions. We were prompted to conduct this experiment when dental team members told us that they visit company websites and consult company representatives for practical clinical information. We look forward to receiving your feedback on this experiment.

When using a two-step product such as CLEARFIL SE PROTECT, the primer portion is a water-based solution with a mild acid. This etching solution is kinder to the tooth structure than the one with phosphoric acid. The bond portion is then applied and light-cured, forming a tight seal with no microleakage or fluid entrapment. The dentinal tubules remain plugged, and the smear layer on the tooth is preserved, thereby becoming part of the hybrid layer. The result is virtually no post-operative sensitivity, as shown in studies done in Turkish universities and the evaluation by The Dental Advisor.

What if a bonding agent could offer you the benefits associated with self-etch technology, as well as cavity cleansing and fluoride-release?

Many clinicians use cavity cleansers to eliminate bacteria which may remain in smaller minimally invasive cavity preps. The newly integrated monomer (MDPB), found in the CLEARFIL SE PROTECT primer, eliminates bacteria on direct contact. This “Antibacterial Cavity Cleansing Effect” is the result of a positively charged MDPB destroying the negatively charged bacteria. MDPB is biologically safe and will not leak after curing. By using CLEARFIL SE PROTECT, the traditional cavity cleansing step is eliminated, thereby saving time for the practitioner.

Fluoride has been found to be beneficial in preventing the recurrence of decay. The bond in CLEARFIL SE PROTECT contains a specially treated sodium fluoride (NaF) that is coated with a unique polymer capsule. This allows release of the NaF while maintaining the physical integrity and strength of the bonding layer. According to research studies at Tokyo Medical and Dental University in Japan, an “acid-base resistant zone” (called Super Dentin) is formed between the bond and dentin behind the hybrid layer, as a result of this fluoride-release. This special zone is able to resist bacteria, if microleakage were to occur. Traditional etch and rinse products cannot form the acid-base resistant zone. The clear advantages associated with the use of CLEARFIL SE PROTECT in providing high-bond strength and durability have been demonstrated both clinically and in the laboratory time and again.

These unique features of CLEARFIL SE PROTECT give practitioners the benefits of state of the art technology, combined with ease of use and peace of mind.
