Temperature rise in the pulp chamber during fabrication of provisional crowns.
This study measured and compared thermal changes in the pulp chamber during the fabrication of provisional crowns by direct method using various brands of autopolymerizing resin systems. The effect of curing the crowns in condensation and addition-reaction silicone putty matrices was also evaluated. The results suggested that the amount of heat transferred in the pulp chamber during the curing of resins may be damaging to the dental pulp and odontoblasts. Curing provisional resin crowns in either condensation or addition silicone putty impressions significantly reduced the temperature rise in the pulp chamber.
