Mechanical and Metallurgical Behavior of Endodontic & Restorative Materials

Dear Colleagues,

In recent decades, the fields of endodontics and restorative dentistry have thoroughly changed thanks to remarkable advances and innovation both in terms of technologies and materials. Since the introduction of nickel-titanium alloy as the material of choice for the manufacturing of endodontic rotary instrument, the percentage of positive outcomes of root canal treatments has increased. This is fundamentally due to the greater mechanical and metallurgical performance of instruments that has led to more efficient, predictable, and conservative shaping of endodontic systems. Since the 2000s, the development of technologies and materials has never stopped, guaranteeing to endodontists several instruments with innovative design and heat treatments. However, improvements are still in progress, and in-depth knowledge of mechanical and metallurgical properties of innovative instruments is required. In addition to the shaping, the concept of obturation of root canal systems is also changing. Regarding this, special attention should be given to the recently introduced bioactive materials (calcium silicate-based endodontic sealers) that release growth factors and form hydroxyapatite-like layers when they come into contact with tissue fluids. Moreover, biomaterial compositions have been investigated for different therapeutic applications, such as regenerative endodontic treatment and endodontic surgery, thanks to their enhanced biological properties, such as cytocompatibility and differentiation of multipotent stem cells.

In accordance with this, the Special Issue will include (but not be limited to) mechanical and metallurgical properties of NiTi endodontic and hydraulic-calcium-silicate-based instruments for obturation, pulp capping, and regenerative and surgical endodontic procedures. Moreover, since endodontic therapies must be followed by proper post-endodontic restoration, attention should be also focused on the mechanical and biological aspects of restorative materials, giving particular attention to the relationship between materials, preparation, and fracture percentage of endodontically treated teeth.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the Special Issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
