Special Issue "New Techniques, Materials and Technologies in Dentistry"

(Applied Sciences)


Guest Editors

Prof. Dr. Ricardo Alves

Prof. Dr. José João Mendes

Prof. Dr. Ana Cristina Mano Azul


Dentistry has seen great technical and technological advances in recent years. These achievements have made it possible to increase the accuracy of the diagnosis, plan treatments more precisely, improve the predictability and durability of certain treatments, make procedures safer and faster, and improve the patient experience and acceptance, among others. The speed at which these advances are developing justifies the publication of a Special Issue that will allow clinicians to be aware of the latest breakthroughs in this field. Topics in this Special Issue include, but are not limited to, the following: new restorative materials, new regenerative materials, new surgical techniques, CAD-CAM systems, artificial intelligence in dentistry, robotics, and translational research. We encourage the submission of papers from different fields of dentistry and related areas. Original in vivo or in vitro studies that describe new therapeutic approaches or materials are strongly welcomed. Reviews on the aforementioned topics will also be considered for publication.



Special Issue "Minimizing the burden of Aging Disorders"

(International Journal of Environmental Research and Public Health)


Guest Editor

Prof. Dr. Catarina Godinho


Assistant Guest Editor

Prof. Dr. Jorge Fonseca


The world is facing a situation without precedent: We soon will have more older people than children and more people at extreme old age than ever before (WHO, Global Health and Aging, 2011). In the last 100 years, populations in developed countries have experienced an unprecedented addition of 30 years to life expectancy. Developing countries are now experiencing this same phenomenon. With this comes the challenge of maximizing health and vitality across these aging population. The compression of morbidity to the latest point in the human life span could unleash a sustained third demographic dividend that benefits all of society (Fried LP, 2016). To accomplish this, society needs to invest in the prevention and treatment of chronic diseases, frailty and all the burden associated to the aging like falls prevention and cognitive impairment, for example. Papers addressing these topics are invited for this Special Issue, especially those combining a high academic standard coupled with a practical focus on providing input strategies to minimizing the burden of Aging.

This special issue of International Journal of Environmental Research and Public Health (IJERPH) focuses on the current state of knowledge on the how society in general and health professionals in particular can contribute to minimizing the burden of Aging Disorders. New research papers, reviews case reports and case series are welcome to this issue. Other manuscript types accepted include methodological papers, position papers and brief reports.

We will accept manuscripts from different disciplines including exposure assessment science, epidemiology, clinical studies, risk and health impact assessment and risk management.


Research Topic “Molecular Features Linking Amyloidogenic Toxicity and Antimicrobial Peptides”

(Frontiers in Molecular Biosciences)


Guest Editor

Prof. Dr. Alexandre Quintas


This Research Topic aims do connect two fields of biochemistry and promote the interchange of knowledge between amyloid diseases and antimicrobial peptides.



Special Issue “Polymers enhancing bioavailability in drug delivery”



Guest Editor

Prof. Dr. Ana Isabel Fernandes 


This Special Issue aims to review the specific functional benefits granted by polymers to formulations, which are very much reliant on polymer structure and design, and result in improved drug bioavailability and therapeutic index.



Special Issue "Novel Developments in the Bioproduction of Biochemicals and Biomaterials"

(Applied Sciences)


Guest Editor

Prof. Dr. Catarina Dias de Almeida


The Special Issue on Novel Developments in the Bioproduction of Biochemicals and Biomaterials in Applied Sciences intends to assemble recent advances and breakthroughs regarding the biological production of commercially important biomolecules. The wide scope of this issue is, however, limited to the production of biochemicals and biomaterials with nonfuel applications. Instead, processes that originate biochemical building blocks, biochemicals, biopolymers, and/or high end-value bioproducts for medical, pharmaceutical, cosmetics, and nutrition markets are preferred.



Special Issue "E-learning and Digital Training in Healthcare Education: Current Trends and New Challenges"



Guest Editors

Prof. Dr. Luís Proença
Prof. Dr. José João Mendes
Dr. João Botelho
Dr. Vanessa Machado


The COVID-19 pandemic had a massive impact on the learning and teaching processes, especially in health education, due to the predominant role of student-patient interaction in that process. In view of this situation, Higher Education institutions around the world were forced to accelerate the introduction of online learning methodologies in areas where this was not the main focus, such as clinical teaching. This special issue is dedicated to current trends and new challenges that emerge from this new e-learning environment, highlighting its potential to revolutionize Health Education and exploring how it can help better prepare future Health professionals for their daily practice.



Special Issue "Periodontal Disease and Female Reproductive Health"

(International Journal of Environmental Research and Public Health)


Guest Editors

Prof. Dr. Maria Alexandra Bernardo
Dr. Vanessa Machado
Dr. João Botelho


The special issue “Periodontal Disease and Female Reproductive Health” is dedicated to scientific and clinical progress on the study of Periodontology in Women of childbearing age. In recent years, a body of scientific evidence has shown an association between periodontal disease and obstetric complications, however, the mechanism of this relationship is not yet fully understood. In addition, recent studies have revealed the potential impact of the subclinical inflammatory state produced by periodontitis on female infertility, which may act as a limiting, but modifiable, risk factor in conception. As contributions to this Special Number, interdisciplinary approaches are encouraged, as well as interventional studies, in addition to systematic reviews that explore the association mentioned above.



Special Issue "Biosensors for the Detection of Nitrogen-Based Compounds"



Guest Editor

Prof. Dr. Maria Gabriela Almeida


Nitrogen is present in the environment in a wide variety of chemical compounds, such as nitrates, nitrites, nitric oxide, nitrous oxide, ammonia, hydroxylamine and also as organic nitrogen. The interconversion of these compounds, in the environment, constitutes the global biogeochemical cycle of nitrogen, which is unbalanced by the human supply of nitrogen compounds, in the soil, water and atmosphere. This represents a threat to Human Health and ecosystems, on a global scale, requiring strict control and monitoring of the most impacting nitrogen compounds, in accordance with national and international legislation. In addition, the search for effective nitrogen oxide analysis methodologies is also present in areas such as food quality control, biomedical research and clinical diagnosis.
