Aim: To evaluate oral environmental changes in cannabis users.
Material and methods: The MEDLINE and Cochrane Central register of controlled trails (CENTRAL) were searched up to April 2007 to identify appropriate studies.
Results: Independent screening of 982 titles and abstracts (MEDLINE-Pubmed) and (Cochrane) papers resulted in seven eligible publications.
Conclusion: Based on the limited data, it seems justified to conclude that with increasing prevalence of cannabis use, oral health care providers should be aware of cannabis-associated oral side effects, such as xerostemia, leukoedema and an increased prevalence and density of Candida albicans.
