Pulp Capping Treatments of Sound and Inflamed Teeth With a Remineralizing Resein-Based Ca-Po4 Cement



Sabine H. Dickens, Glenn M. Flaim, Gary E. Schumacher, F Eichmiller, Duane R. Schafer, R B. Rutherford


The pulp capping activity of an adhesive resin-based Ca-PO4 cement (RCPC) was evaluated on sound dog teeth after (7, 28 or 90) d, and on inflamed and sound ferret pulps capped for 45 d with RCPC or a light-cured calcium hydroxide (LC-CH) cement as a control. Inflammation, bacteria, and dentin bridge formation were evaluated histologically. The results indicated that in RCPC-treated dog teeth, bacteria and residual inflammation were lower than in control specimens. After 45 d and 90 d all exposed sound RCPC-treated pulps showed dentin bridging. Nearly complete dentin bridges were found in 75 % of the RCPC-treated inflamed ferret teeth. Only minor or no dentin bridging was found in inflamed teeth treated with LC-CH. The success of RCPC is attributed to the initial high pH, continuous release of calcium and phosphate ions, higher strength of the material and to moderate dentin adhesion that may have contributed to low inflammation and bacterial infiltration.
