Introduction: Periodontal Disease during pregnancy can influence in maternal-fetal health. Two hypotheses have been established in relation to oral health and alterations in pregnancy. The first one determines that periodontal disease causes immunological changes, which causes complications during pregnancy. The second hypothesis proposes that oral bacteria colonize the placenta, cause inflammatory responses and result in preeclampsia and prematurity. Objective: To carry out a systematic review on periodontal disease and its relationship with complications during pregnancy. Methodology: A systematic review was carried out using PRISMA methodology. An electronic search was conducted in three databases (PUDMED, CINAHL and SCOPUS) for articles published in English. The keywords or search terms used were the following: Low birth weight / Low birth weight; Periodontal disease / Periodontal disease, pregnant / Pregnant women. Results: For this review, 19 specific articles on periodontal disease and its relation to pregnancy complications have been selected. Discussion / Conclusions: The publications analyzed in this study, according to their results, revealed that the association between periodontal disease and the health of the pregnant women and their baby is still contradictory.

Medicines are dangerous for health and the environment, so it is important to know the proper way to dispose of them. Objective. Identify the knowledge of the students of the different educational programs of the ICSa on the management of the expired medications. Materials and methods. An observational, cross-sectional and prospective epidemiological study was carried out by applying a survey to the students of the ICSAs degrees. Results. A total of 50 articles were applied in which it was demonstrated that the total of the population knows that it is an outdated medicine, however, 38% use conventional common waste as their final destination, only 24% special container and 54% consider that there is a lack of information about their correct disposal. Conclusion. It is appreciated that the surveyed population knows that it is an outdated drug but the great majority is not able to identify the importance of the appropriate waste, this despite the fact that they are aware that they can appear anywhere. So working from the educational field, under the constructivist model of education will prevent the results in environment and health are not positive.

Aim. To determine the reasons of vitamin D deficiencies detected in the Spanish infant-juvenile population. Method. Different databases of scientific publication were consulted through a systematic review. , Systematic reviews and original articles of meta-analyses were used to fulfill the proposed objective. Results. The evidence reveals that there are many causes that result in a decrease in vitamin D levels in the population under study: pregnancy and lactation, food, diseases, medications and sun exposure; being the latter the most influential as the main source of this vitamin and having numerous barriers that prevent solar radiation from making its effect on existing precursors in the dermis. Conclusions. No general recommendations can be made to prevent vitamin D deficiency in the Spanish child and adolescent population with the results obtained. More studies are needed to specify adequate levels and to determine if there is a real deficiency of this micronutrient in our community.
