Abstract
The purpose of this pilot study was to evaluate the pulpal response to compounds that promote strong adhesion to dentin and enamel. Two adult beagle dogs were used. Class V cavities were prepared on the labial surfaces of the teeth using an air turbine handpiece and water coolant. After application in sequence of ferric oxalate, water, air, an acetone solution of NPG-GMA (the addition reaction product of N-phenylglycine and glycidyl methacrylate), acetone, air, an acetone solution of PMDM (the addition reaction product of pyromellitic dianhydride with 2-hydroxyethyl methacrylate), and then air, all experimental cavities were restored with Adaptic. The teeth from one quadrant in each dog received Adaptic without any pretreatment (control). The findings indicated that 28 days postoperatively there were no inflammatory changes in the pulps of the experimental teeth and mild responses in the control teeth. At 3 days, while the control teeth showed some inflammatory response, the experimental teeth did not exhibit significant inflammatory response. Within the parameters of this investigation, the results suggest that the experimental materials did not cause pulpal irritation. Furthermore, it appears that they provided some measure of pulp protection compared to the controls. © 1988 Munksgaard International Publishers Ltd.
