TOKYO, Japan: In evaluating the properties of a universal dental adhesive, many clinicians will consider its compatibility with various etching techniques and with a wide range of indications. After all, universal adhesives are typically used as bonding agents for direct restorations made of light-polymerising composite, for immediate dentinal sealing, for repair procedures and for indirect restorations. However, “universal” should also indicate compatibility with any resin composite and self-adhesive resin cement, regardless of the manufacturer.
