title: Human pulp response to a new composite system. Vytol composite restorative and bonding agent.
abstract: A new two-paste composite system (Vytol and Vytol Bonding Agent) was evaluated to establish its level of pulpal response in human teeth and to determine whether a calcium hydroxide base is required. Class V cavity preparations were cut in seventy-two teeth of ten male patients whose ages averaged 52.5 years. The teeth were restored and extracted at 1 to 7 days, 12 to 14 days, and 47 to 56 days. Histologic evaluation indicated that the unlined Vytol System reacted very similarly to other commercially available composite restorative materials and that a calcium hydroxide base is effective in reducing or eliminating adverse pulp responses.
