"This is called the intrapulpal
pressure which causes the pain.
anaesthesia consists in direct placement of the needle in the pulp of a tooth and application of anaesthetic.
Appropriate endodontic therapy must be performed before hemisection to avoid intrapulpal
dystrophic calcification and postoperative tooth sensitivity.
A digital thermocouple was fixed within the pulp chamber, and the same teeth were used as vital specimens (irrigating with water at 37[degrees]C to simulate the effect of intrapulpal
blood circulation) and devitalized specimens (without irrigation), thereby facilitating the comparison of the effect of irrigation.
After dental trauma, the intrapulpal
bleeding is the most common etiology of tooth discoloration.
* Patients who receive intrapulpal
and buccal infiltration with inferior alveolar nerve block.
A classic animal study by Zach and Cohen  established a threshold temperature for irreversible pulpal damage caused by the application of external heat to a sound tooth; a 5.5[degrees]C increase in intrapulpal
temperature induced necrosis in 15% of pulp samples tested.
When the gold-standard test elicited a painful response, a second cartridge of mepivacaine was given as a repetition of the IANB or the intrapulpal
technique, and a painless endodontic treatment was performed.
A study done by Kusai Baroudi and others compared the intrapulpal
temperature rise between the five flowable and three non flowable composites using light-emitting diode (LED) and halogen (quartz-tungsten-halogen) light-curing units (LCUs).
We started each measurement after verification that intrapulpal
temperature was stable at 37[degrees]C.
