Status of Research on Dental Caries during Pregnancy: A Biometric Exploration.

AIM: To describe the bibliometric characteristics of the state of scientific production on dental caries during pregnancy. MATERIALS AND METHODS: A bibliometric study with a sample of 408 publications indexed in the Scopus database, which were selected based on a search strategy that included logical operators and the term MESH. The Scival tool was used to analyze the metadata. RESULTS: Jamieson Lisa Marie is positioned as the author with the most publications, and Schroth Robert as the one with the best-weighted impact (FWCI: 37.7). High-impact journals such as BMC Oral Health, Journal of Dental Research, and BMC Public Health stand out for their productivity and an average number of citations. The United States has a large number of publications and evidence of networks of scientific activity with Australia, Canada, and Brazil. The University of Adelaide leads the production and the work of two Latin American institutions (Universidade de São Paulo and Universidade Federal do Maranhão) stands out. International collaboration has improved during the study period. CONCLUSION: Scientific production on dental caries during pregnancy is increasingly published in high-impact journals, with growing international collaboration. The United States leads in publications, while Australian institutions are the most productive in this field. CLINICAL SIGNIFICANCE: Caries during pregnancy is a problem that has an important impact on maternal and perinatal health; thus, its timely management and prevention are important areas of research in the field of oral health.

Prevention of Staphylococcus epidermidis biofilm formation using a low-temperature processed silver-doped phenyltriethoxysilane sol-gel coating.

Sol-gel coatings which elute bioactive silver ions are presented as a potential solution to the problem of biofilm formation on indwelling surfaces. There is evidence that high-temperature processing of such materials can lead to diffusion of silver away from the coating surface, reducing the amount of available silver. In this study, we report the biofilm inhibition of a Staphylococcus epidermidis biofilm using a low-temperature processed silver-doped phenyltriethoxysilane sol-gel coating. The incorporation of a silver salt into a sol-gel matrix resulted in an initial high release of silver in de-ionised water and physiological buffered saline (PBS), followed by a lower sustained release for at least 6 days-as determined by graphite furnace-atomic absorption spectroscopy (GF-AAS). The release of silver ions from the sol-gel coating reduced the adhesion and prevented formation of a S. epidermidis biofilm over a 10-day period. The presence of surface silver before and after 24 h immersion in PBS was confirmed by X-ray photoelectron spectroscopy (XPS). These silver-doped coatings also exhibited significant antibacterial activity against planktonic S. epidermidis. A simple test to visualise the antibacterial effect of silver release coatings on neighbouring bacterial cultures is also reported.

Aspectos epidemiológicos, sociais e sanitários de uma área no Rio Negro, estado do Amazonas, com especial referência às parasitoses intestinais e à infecçäo chagásica / Epidemiological, social, and sanitary aspects in a area of the Rio Negro, state of Amazonas, with special reference to intestinal parasites and Chagas'Disease

Estudo seccional realizado na populaçäo residente em um de cada quatro domicílios habitados na cidade de Barcelos (no norte do estado do Amazonas), visando avaliar as condiçoes sociais, sanitárias e os indicadores específicos para as parasitoses intestinais e para infecçäo chagásica. Foram aplicados dois questionários, um domiciliar para avaliar os aspectos sociais e sanitários, e outro individual, para a avaliaçäo das condiçoes sociais e epidemiológicas da populaçäo.
