Multifunctional bases and liners.

Three one-minute techniques are presented using anhydrous resin modified glass isonomer, an antibacterial and multifunctional base and liner. The isonomer is placed in deep areas of caries, as insurance, and to desensitize the tooth and fill gaps. The anhydrous glass accepts water from the dentin to fill potential contraction gaps from polymerization shrinkage of the composite fill.
