Background: The heat produced by provisional restoration materials may injure the dental pulp. This study measured and compared peak temperatures during polymerization of 5 materials used in the fabrication of provisional restorations.
Methods: The tested materials were 2 self-curing resins (Integrity and Protemp) and 3 dual-cure resins (Iso-Temp, TCB Dual Cure and Provipont DC). A mould the size of a maxillary molar tooth was fabricated to contain 0.5 cc of resin. The temperature rise of the different materials was recorded every 10 seconds over a 10-minute period.
Results: The rise in temperature of Integrity (peak temperature of 33.8oC) and Protemp Garant (35.6oC) was significantly higher than the rise in temperature of Iso-Temp (29.5oC), TCB Dual Cure (28.4oC) and Provipont DC (29.5oC).
Conclusion: Use of the dual-cure resins in provisional restorations may reduce the risk of pulp injury.
