Summary. Pulpal responses to a conventional amalgam, New True Dentalloy, and a high copper amalgam, Solila Nova, were studied over a period of 6 months. Kalzinol was used as a negative control material. Standardized Class V cavities were prepared in the canine teeth of male ferrets under ketamine/xylazine anaesthesia. The animals were killed with excess pentobarbitone and the teeth extracted after 7, 14, 28 and 183 days. After processing, the teeth were serially sectioned and assessed qualitatively and quantitatively according to standard criteria. There were some variations in the pulpal responses at 7 days and 14 days post‐operatively but at 28 days and 183 days, the responses under the two materials were similar with only slight pulpal inflammation being observed. No pulpal inflammation was present beneath surface‐sealed Solila Nova cavities. Gram positive micro‐organisms were observed at the interface of cavity wall and material in conventional cavities but not within those surface‐sealed with Kalzinol.
