Abstract: The purpose of this histopathological study was to investigate the pulpal reaction to New Panavia (TPN-S) in adult dogs at the intervals of 3, 30 and 90 days after filling.The results were as follows:TPN-S induced a slight pulpal change, and no reparative dentin was formed on the primary dentin in each experimental case.There was no significant difference in the pulpal response between TPN-S and the zinc oxide-eugenol cement (positive control).Contrarily, the silicate cement (negative control) induced relatively intense damage to the pulp, especially in the 90-day postoperative cases.No bacterial penetration was observed in the experimental series of TPN-S and the zinc oxideeugenol cement, but bacterial invasion did occur in a few cases of silicate cement 90 days after preparation.The results of this study suggested that TPN-S showed a very weak reaction to dental pulp.
