Dental Biomaterials and Tissue Engineering

About this Research Topic

Background

Dental biomaterials research is a vital and evolving domain within dental science that focuses on the development, characterization, and clinical evaluation of materials used in the prevention, diagnosis, restoration, and regeneration of oral tissues. These materials are expected to function under complex conditions in the oral cavity, which presents unique challenges such as moisture, pH fluctuations, mechanical loading, and microbial presence. As a result, dental biomaterials must exhibit a combination of properties—biocompatibility, mechanical strength, adhesion, aesthetics, and long-term durability.

The field has grown significantly over the past few decades. Traditional materials such as dental amalgam and gold alloys have largely given way to more advanced alternatives like resin composites, glass ionomer cements, ceramics, and bioceramics, each tailored for specific clinical applications ranging from restorative procedures to endodontics, prosthodontics, and implantology. Adhesive systems have revolutionized conservative dentistry by enabling minimally invasive restorations with strong bonds to both enamel and dentin.

Modern dental biomaterials research is inherently interdisciplinary, drawing from materials science, polymer chemistry, biomechanics, microbiology, and tissue engineering. Researchers aim not only to improve existing materials but also to design bioactive and smart materials that interact beneficially with oral tissues, promote healing, or even adapt to environmental changes in the mouth. The advent of nanotechnology, digital dentistry, and 3D printing has further expanded the frontiers of the field, offering new possibilities for patient-specific treatment solutions and regenerative therapies.

Despite significant advances in adhesive dentistry, the long-term bond durability to dentin remains a major clinical challenge. While contemporary adhesive systems provide satisfactory initial bond strength, their performance often deteriorates over time, particularly in the humid and enzymatically active environment of the oral cavity. This degradation compromises restoration longevity and leads to microleakage, secondary caries, and restoration failure.

To enhance the durability of dentin bonding, research must address both material design and biological interaction. Potential approaches include:

1. Enzyme Inhibition Strategies:

• Use of MMP inhibitors (e.g., chlorhexidine, benzalkonium chloride) to prevent collagen breakdown within the hybrid layer.
• Development of adhesives with built-in protease inhibitors.

2. Bioactive and Remineralizing Adhesives:

• Incorporation of bioactive fillers like calcium phosphates, bioactive glass, or nanoparticles that can promote remineralization and hybrid layer stability.
• Use of functional monomers like 10-MDP that form stable chemical bonds with hydroxyapatite and resist hydrolysis.

3. Improved Resin Chemistry:

• Development of hydrophobic, solvent-free resin systems that are less sensitive to water uptake.
• Incorporation of nanogels, dendrimers, or nanofibers to reinforce adhesive layers.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and it falls under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

  In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
