Because twice-daily tooth-brushing behaviour and sound dentition in 9-year-olds were associated with their mothers' positive oral health-related attitudes, in developing oral health promotion programs for children and adolescents, the considerable potential of mothers should be a major focus of oral health professionals.

When a school-based oral health intervention involves parents it may result in a significant improvement in the gingival health of preadolescents with poor gingival health at baseline.

Objective: High prevalence of Dental and periodontal problems during the gestation period may have a negative effect on oral healthrelated quality of life (OHRQoL) in pregnant women. This systematic review aimed to perform a quality assessment and provide a critical overview of the current research available on OHRQoL in pregnant women. Methods: For this systemic review, all original and peer-reviewed human studies, which investigated OHRQoL of women during pregnancy or postpartum period were searched. Studies were screened in title and abstract for the relevance by two independent investigators. Methodological quality was assessed using modified items recommended by the Newcastle–Ottawa Scale for observational studies. Result: All of the eight included studies had a cross-sectional design. Meta-analysis was not possible due to the heterogeneity on key aspects among the included studies. Thus, the data from the studies were evaluated qualitatively. The overall risk of bias of the included studies was low. Conclusion: The main conclusion of this review is that the presence of signs and symptoms of dental and gingival disease negatively affects the selfperception of OHRQoL in pregnant women. The most affected domains of OHRQoL in pregnant women were related to mental and psychological discomfort followed by physical and functional problems.
