Influence of experimental provisional cements containing zeolite, bone hydroxyapatite and linoleic Acid on bond strength of composite to dentin in vitro.

Purpose: to evaluate the dentin bond strength of a composite resin material after the removal of two experimental cements containing zeolite, bone hydroxyapatite and linoleic acid, and one conventional glass-ionomer cement intended as provisional cements.

Materials And Methods: forty extracted caries-free, erupted permanent third molars were used. Experimental provisional cements containing zeolite and bone hydroxyapatite (BHA) and one conventional glass-ionomer cement (GIC) were placed on the dentin surfaces and covered with tinfoil.
