Do dental liners and bases benefit a restoration? Originally developed for retention restorations, liners and bases were believed to seal the dentinal tubules to protect the pulp, but later research showed their ineffectiveness.
As restorative dentistry transitioned to adhesive materials and protocols, their use continued, but are they still necessary to seal the pulp? In this episode, Dr. David Alleman, DDS, discusses the research and effectiveness of liners and bases, and how the right adhesive protocols can render them unnecessary by using your dentinal bonding system to seal the tooth instead.
