In emphasizing the oral health-promoting information, the value of social support received through their participation in the programme and through the interest of the researchers should not be overlooked. Social bonds and supportive interactions
have been widely recognized as important factors for psychological well-being and general health, and may be seen as an effective buffer or mediator of life stress (38). The stress alleviating effect of social support was found especially
among low-income pregnant women who received lay visitors (39). Therefore, part of the outcome of this research may reflect the interest and support shown by the researchers.
