When I graduated from dental school in 1988, Durelon™ was my permanent cement of choice. It seemed to work well until it started to turn mushy about five years after cementation. Maybe it’s not a bad idea to have the crown fall off every five years to check the prep! When all the hype with glass ionomer cements started, I switched over. But when I had too many cases of post-operative sensitivity to ignore, I went running back to Durelon. With the advent of an excellent class of resin-reinforced glass ionomer cements, Durelon has decreased in use as a permanent cement. My reintroduction to Durelon was through Dr. Bill Strupp, who has used Durelon as a temporary cement for decades. We started using it about 10 years ago for our BioTemps^® in large crown and bridge cases, and the temps simply don’t come off. Due to its relatively neutral pH value, there is essentially no post-operative sensitivity with this cement, and it is well tolerated by the gingival as well.
