Intrapulpal heat generation during provisionalization: effect of desensitizer and matrix type.

Purpose: This study investigated the effect of different matrices and application of a desensitizer on pulpal temperature rise during direct provisionalization.

Materials And Methods: The apical third of a second premolar was resected and pulpal tissue was removed. Silicone heat-conducting medium was injected, and a J-type thermocouple was inserted into the pulp chamber and sealed.
