Research into the use of temporary restorative materials between sessions is one of the determining factors in the success of endodontic treatment. These materials temporarily seal the tooth between sessions, preventing oral fluids, microorganisms and other products from entering the root canal.
Burger, Cooley and Garcia-Godoy (1992), evaluating the effect of thermocycling times on dentin adhesion strength, indicated 125 thermal cycles of 5º-55ºC, with an immersion time of 15 seconds. Beach et al. (1996) compared the bacterial infiltration of Cavit, IRM and TERM (composite resin) materials in vivo. According to this study, Cavit provided a significantly better seal than the others. Studying class II restorations using only glass ionomer cement or glass ionomer cement associated with composite resin and dentin adhesive, Yap et al. (1996) observed that those restored only with glass ionomer showed little or no infiltration.
