Cannabinoid receptor 1 (CB1R) expression in rat dental pulp

Oral Science International“Accumulating evidence supports the role of the cannabinoid system in providing an antinociceptive effect in various painful conditions.

This effect is mediated through the Cannabinoid receptor 1 (CB1R) expressed on nociceptive afferent nerve terminals.

To investigate whether this receptor plays a similar role in dental pain, we studied the presence and distribution of CB1R in rat dental pulp.

CB1R was present on nerve fibers in rat dental pulp and possibly plays a role in dental pain mechanisms.

Interestingly, CB1R has recently been demonstrated in human dental pulp.

This strongly suggests that CB1R could be a therapeutic target for dental pain management.”
