abstract="AIM: The aim of this systematic review and meta-analysis was to assess the scientific evidence on the association between depression and periodontitis. <br><br>METHODS: An electronic search was conducted in three databases until October 2015 (PROSPERO-CRD42014006451). Hand searches and gray literature were also included. Search retrieved 423 potentially studies. Two independent reviewers selected the studies, extracted data, and assessed risk bias through a modified version of Newcastle-Ottawa scale. Meta-analysis was performed for the presence/absence of periodontitis (dichotomic). Summary effect measures and odds ratio (OR) 95%CI were calculated. <br><br>RESULTS: After selecting the studies, 15 were included in the systematic review (eight cross-sectional, six case-control, and one cohort study). Six studies reported that depression was associated with periodontitis, while nine studies did not. The majority of studies had low risk of bias by methodological quality assessment. Meta-analysis of seven cross-sectional studies showed no significant association between depression and periodontitis (OR=1.03, 95%CI=0.75-1.41). <br><br>CONCLUSION: Findings from the present systematic review showed a great heterogeneity among the studies and the summary effect measure of the meta-analysis cannot affirm an association between depression and periodontitis. Future studies with different designs in distinct populations should be conducted to investigate this association. This article is protected by copyright.
