Study Summary

This protocol is for a number of in vitro studies using human surgical biopsies and evaluating the pharmacology and genetics of human nociceptors ("pain detecting") neurons

Primary Outcome

Extracted human teeth are sectioned to obtain the crown dental pulp which is placed in a well plate. The pulp is moved every twenty minutes through proprietary substances for a total of 60 to 120 minutes depending on the specific experiment. After each 20 minute fraction, the buffer solution in each well plate is collected, labeled and placed in the -80 freezer along with the pulp sample.
