Histological evaluation of pulpal responses to four composite resins in dog dental pulps.
The pulpal responses to four composite resins--used in dentistry for anterior tooth restorations--were studied in adult dog teeth. The materials were placed in Class V buccal cavities following the instruction of the manufacturers and their effects were evaluated after 72 h, 30 and 60 days using routine histological methods. The results indicated that a pulpal response was observed only at the 72 h time interval in all the resins investigated, and the index of this response was less than 1 for all of them.
