Objective

: To analyze the possible influence of cannabis use on periodontal disease, highlighting the available evidence and identifying the associated variables in the studies.

Materials and methods

: We conducted a scoping review applying a structured search method in PubMed/MEDLINE, Science Direct, LILACS, SciELO including publications until May 2017.

Results

: In vivo studies showed greater bone loss in animals exposed to cannabis. Clinical cases show that chronic cannabis use may result in gingival enlargement (with clinical features similar to phenytoin induced enlargement) and localized severe chronic periodontitis. Most of the epidemiological studies confirmed the possible association between cannabis and periodontitis.

Conclusions

: The consumption of cannabis seems to be associated with a greater presence of periodontitis. However, the specific mechanism by which cannabis acts in the gingival tissues is unknown.
