Are there Certain Adhesives and Cements that Cannot Be Used Together?

Many clinicians have a product preference when it comes to adhesives and resin cements. What they may not realise is that certain adhesives when used in combination with certain cements might not produce the expected results.

Today, we’re bringing you this video post crafted and delivered by Dr. Rick Carvalho who will answer a common, clinician question: Are there certain adhesive that cannot be used together?

About Dr. Rick Carvalho 

Dr. Carvalho is a Professor in the Department of Oral Biological and Medical Sciences, Division of Biomaterials at the University of British Columbia. You can read a full bio of Dr. Carvalho by following this link.

During this slide-based video presentation, Dr. Carvalho reviews:

  • The nature of incompatibility chemical and permeability issues with self- or dual- cured resin cements.
  • How surface acids of adhesives consume amines that should promote self-curing of cement.
  • Preventing chemical incompatibility by using activators (bonding of dual cure cements and core build-up materials and bonding of self-cure composites.)
  • How “blisters” caused by permeability can form on the adhesive’s surface and compromise bonding.
  • Solutions for preventing incompatibility and chemical issues between adhesives and resin cements.
