"Ser criança'' - an oral health literacy program for vulnerable children and fa...

Background: Oral health literacy and knowledge about primary prevention methods are essential to decrease possible effects of poor oral health on systemic health. This is more evident among the vunerable communities. The objectives of this work consists in the establishment of methods to promote oral health literacy applicable to the participants of the “Ser Criança” program, namely: development of a website—“S...

Factors associated with the prevalence of apical periodontitis: an observationa...

Objectives: Apical periodontitis is a lesion of endodontic origin caused by an immune response to necrotic and infected dental pulp. Since apical periodontitis can persist after endodontic treatment, radiographic diagnosis is crucial. This study evaluates factors associated with the prevalence of apical periodontitis in a Portuguese population using the full-scale periapical index. Methods: A cross-sectional st...

Degree of contamination of gutta-percha points by Staphylococcus aureus (MRSA/M...

Methicillin-resistant Staphylococcus aureus (MRSA) is considered one of the most harmful bacteria to human health. Dentistry, like all healthcare disciplines, places great emphasis on preventing scenarios that may result in cross-infection. Although various tested and already used materials are suitable for filling the root canal system, Gutta-Percha (GP) remains the preferred and widely accepted gold standard....

O4 - Exploring the biological properties and regenerative potential of biomater...

Life expectancy has improved signifcantly and, along with the declining birthrate, has contributed to the aging of populations, especially in industrialized countries. Alas, aging is intrinsically associated with the incidence of health problems including bone and tooth loss that require suitable solutions to support the quality of life. To meet these demands, signifcant research eforts have been undertaken to ...

P9 - Antimicrobial properties and bioactivity potential of smart nanoparticles ...

Tooth decay is one of the greatest causes of tooth loss in the world. This not only afects the patient’s quality of life but also carries an economic burden associated with the need for multiple reinterventions. Endodontic treatment aims to preserve teeth by cleaning, disinfecting and flling/sealing the root canal. Despite the high success rate of endodontic treatment, failures do occur in a large number of cas...

P8 - Marine fungi exhibit antimicrobial activity against human oral pathogens

The emergence of resistance to antibiotics and antimycotics has become a challenge in the treatment of infectious diseases, including infections of the oral cavity. Marine fungi are a source of novel biologically active compounds, namely in what concerns the development of antimicrobial and anticancer solutions. Our study aimed to test the antimicrobial activity and the cytotoxicity of the extracts of the two r...

#064 Caracterização biológica dos derivados do osso de choco para aplicação em ...

Objetivos: Avaliar as propriedades antimicrobianas e citotóxicas do osso de choco de forma a selecionar o material de medicação intra-canalar com maior potencial de aplicação em endodontia. Materiais e métodos: A citotoxicidade de osso de choco hidrotermalmente processado foi estudada numa linha celular proveniente de rim de macaco (células VERO) de acordo com a Norma ISO 10993? 5. A viabilidade celular das cél...

Dique de borracha na diminuição de microrganismos nos aerossóis

Objetivos: Avaliar se o dique de borracha interfere na disseminação de microrganismos em aerossóis gerados durante o uso de instrumentos rotatórios no tratamento de cáries. Materiais e métodos: Foram realizados 20 tratamentos de cárie, sendo dez com dique de borracha (DB) e dez sem dique de borracha (SDB). Foram utilizados três pontos de recolha: operador (DB n=10; SDB n=10), assistente (DB n=10; SDB n=10) e ba...
