Dental liner

Dental liner – What is it?

Dental liner is a term that refers to a material or technique used to prevent sensitivity in deep dental fillings.  There are a variety of products and techniques used.  Products can be bioactive and/or resin based.  MTA, glass ionomer, resin-modified glass ionomer, calcium silicate, and others are common materials used today.

Does a dental liner prevent sensitivity?

It is my personal opinion they do not.  That does depend on one’s bonding technique though.   I very rarely will have reported sensitivity since starting to use gluma under my restorations.

Dental liner research

PEARL network study, which I am a member of, found no difference in reported post op sensitivity when a RMGI was used.  Strober 2013 JADA

Glass ionomer helped with sensitivity against total etch bonding (no gluma).  Akpata 2001

No difference in SE TE or liner use with modern techniques and materials.  Burrow 2009 Oper Dent

TE v gluma v CHX no difference Sobral 2005
