Osseous Characteristics of Mice Lacking Cannabinoid Receptor 2 after Pulp Exposure

CB2 plays a role in mandibular bone metabolism. Increased bone density in CB2 KO mice may contribute to the smaller periapical lesion size observed after pulp exposure in KO compared with WT mice. Additional experiments are needed to further elucidate the function of CB2 and clinical implications of cannabinoids on bone and periapical pathosis.
