A printed informational leaflet is developed with two sections: "For Mothers" and "About the Baby," following international pediatric dentistry recommendations. A pilot study tests the clarity and completion time of the questionnaires. Participants are informed about the study, sign the consent form, and complete an initial questionnaire about oral health knowledge during their hospital visit. They receive the leaflet and complete the same questionnaire again after a period of time to assess changes. Most follow-up questionnaires are conducted by phone.

The intervention consists of a printed informational leaflet for pregnant women. The leaflet has two sections: "For Mothers," which explains oral health care during pregnancy, and "About the Baby," which provides oral health recommendations for the newborn. The content is based on recommendations from international and national pediatric dentistry associations (AAPD, EAPD, ALOP, SEOP). Participants read the leaflet during their hospital visit and take it home for reference. The leaflet aims to improve participants' knowledge, attitudes, and practices regarding oral health during pregnancy and in the first years of the child's life.

Participants complete a questionnaire about oral health knowledge, attitudes, and practices during pregnancy and in the first years of the child's life. The difference between baseline and follow-up scores is analyzed to assess whether the informational leaflet improves knowledge, attitudes, and practices.
