Epidemiological studies have suggested that maternal periodontitis affects the fetal-placental unit, with an increased risk of adverse pregnancy outcome. Indeed, it has been suggested that the direct or indirect action of parodontopathogenic bacteria induces an inflammatory cascade that leads to spontaneous premature labor. Also, non-treatment of caries and periodontal disease can lead to acute pain and stress. This may promote self-medication and the inappropriate use of analgesic medications, potentially harmful to the health of the fetus. As part of the prevention of complications of pregnancy associated with oral diseases, the National Agency for Accreditation and Evaluation in Health (ANAES) has set up a system that allows any pregnant woman to consult between the 4th and 7th month of pregnancy, an oral health professional to carry out a complete assessment and free care. This study aims at evaluating this device among pregnant women and healthcare professionals 4 years after its implementation. On the other hand, it will make it possible to look for a possible link between the realization of an oral prenatal follow-up and the outcome of the pregnancy.

This study will concern two populations:

• pregnant women attending hospital during pregnancy monitoring and / or being hospitalized in one of the maternity wards associated with the project,
• health professionals in charge of the follow-up of these pregnant women and their childbirth.
