The achievement of an adhesive bond between enamel and dentin and restorative materials has been an objective for generations of dental research workers. Dentin bonding agents have been classified into generations, with earliest generations showing unreliable bond strengths. Some currently available systems show in vitro shear bond strengths to dentin which are similar to the bond strength to enamel, this being considered an ideal property. Alongside other previously recognized ideal properties, appropriate criteria for state-of-the-art dentin bonding systems at the present time may be considered to include the ability of systems to operate in moist environments and be technique insensitive.
Clinical success of resin-bonded fixed partial dentures is primarily dependent on their long-term retention. Retention rates of resin-bonded prostheses placed in 66 patients treated by three dentists in private practice were evaluated in the present study. Seventy-seven resin-bonded fixed partial dentures were followed over a period of 1 year to 11 years. Thirty (39%) became dislodged, but nine were successfully rebonded; thus there were 21 failures (27%). Prosthesis location and operator expertise minimally influenced the longevity of these restorations, but the luting agents tested in this sample had a profound impact on retention. Debonding rates were excessive for some materials tested, whereas other agents proved to be predictable. Modifications in preparation design that enhanced resistance form were also likely contributors to improved retention rates.
