Abstract
This histopathological study was undertaken to investigate the pulpal irritation of Super Bond C & B in adult dogs at the intervals of 3, 7, 14, 30, 60, 90 and 120 days after filling. The results were as follows:
1. At the 3-day and 7-day postoperative intervals more than half cases showed the pulpal changes directly under the cavity, however, its degree was not severe, but moderate.
2. At the 14-day and 30-day postoperative intervals few cases showed the changes. Its degree was mild with a tendency of decreasing the changes.
3. At the 60-day, 90-day and 120-day postoperative intervals many cases showed no pulpal changes. The number of the cases with reparative dentine formation was reparatively few.
4. As a result of this study, it can be considered that Super Bond C & B was less irritative to the pulp.
