RESUMO
Maternal mental problems may lead to a negative effect on children's oral health (COH). The aim of this study was to systematically review the literature to answer the question: Are maternal mental disorders (MMD) associated with COH from zero to 12 years old? Electronic searches were performed in five databases with no language restriction. Cohort, case-control, and cross-sectional studies were included. A total of 1183 references were identified, and seven studies were included. In relation to MMD studies investigated: Common Mental Disorders (n = 2), Major Depressive Disorder (MDD) (n = 2), symptoms of depression (SD) (n = 3), Alcohol-related diagnosis (n = 1), and symptoms of anxiety (n = 2). As outcome, the studies investigated dental caries (n = 5), gingivitis and periodontal diseases (n = 1), sleep bruxism (SB) (n = 1), and malocclusion (n = 1). Positive association was found between MDD and OH (SB and dental caries). There was no MMD associated with malocclusion. Alcohol-related diagnosis showed a positive association with gingivitis and periodontal diseases and no association with dental caries; anxiety had a positive association with dental caries and no association with SB. The heterogeneity of the data precluded precise conclusions to be drawn, but MMD may have influence on COH.
