“Medical and recreational cannabis use is increasing significantly, but its impacts on oral health remains unclear.
The aim of this study is to investigate the effects of tetrahydrocannabinol (THC), the major active component in cannabis, on periodontal fibroblast cell adhesion and migration to explore its role in periodontal regeneration and wound healing.
Both CB1 and CB2 were expressed in periodontal tissues but with different expression patterns. THC promoted periodontal cell wound healing by inducing HPLF cell adhesion and migration. This was mediated by focal adhesion kinase (FAK) activation and its modulation of MAPK activities. The effect of cannabinoids on periodontal fibroblast cell adhesion and migration were mainly dependent on the CB2.
These results suggested that cannabinoids may contribute to developing new therapeutics for periodontal regeneration and wound healing.”
