Reduction of postoperative pain: a double-blind, randomized clinical trial

Article Abstract:

Adhesive resin liners (AL) under dental amalgam fillings may be more effective against postoperative tooth sensitivity than copal varnish and glass ionomer liners (CV). Liners and varnishes seal the surface of the tooth cavity before the filling material is applied. Sixty patients received Amalgambond Plus adhesive liner or a base of Copalite copal varnish with Vitrebond glass ionomer where appropriate. Patients in the AL group reported less postoperative sensitivity than those in the CV group. Patients in the CV group were more cold-sensitive than before receiving treatment.

Clinical performance of bonded amalgam restorations at 42 months

Article Abstract:

An adhesive resin liner under a dental filling appears to be as effective as copal varnish and zinc phosphate cement. This was the conclusion of researchers who followed 14 people who had received an adhesive resin liner and 16 who had received the conventional bases. After 42 months, all the restorations were intact, in good condition, and were free of secondary cavities.

The performance of bonded vs. pin-retained complex amalgam restorations: a five-year clinical evaluation

Article Abstract:

Bonding a large filling with a 4-META-based resin is as effective as using self-threading pins, according to a study of 60 fillings. This is especially useful for complex amalgam fillings that replace at least one cusp.
