Evaluation of cannabinoid receptors type 1-2 in periodontitis patients.

The lower expression of CB2 receptors in the periodontitis group may be due to the reduced protective effect of anti-inflammatory agents. These elements include cannabinoids and the imbalance leading to the predominance of pro-inflammatory effects. Therefore, the local effects of cannabinoids as an immunomodulator could be useful for oral inflammatory diseases such as periodontitis.
