Special Issue Information

Dear Colleagues,

Dental materials play a pivotal role in modern dentistry, influencing restorative, prosthetic, preventive, and regenerative treatments. Their continuous evolution is critical to improving patient outcomes, durability, and esthetic results in clinical applications. The journal of Applied Sciences is pleased to announce a Special Issue dedicated to dental materials. This publication aims to bring together high-quality papers addressing fundamental and applied aspects of dental materials, including their innovation, characterization, clinical applications, processing techniques, as well as current and future challenges in this area.

Topics of interest include, but are not limited to, the following:

  • Innovative biomaterials for restorative and regenerative dentistry;
  • Mechanical, biological, and esthetic characterization of dental materials;
  • Biocompatibility, wear resistance, and antimicrobial properties;
  • Emerging challenges in material selection, durability, and patient-specific solutions;
  • Digital dentistry and smart materials for next-generation applications, etc.

We appreciate your interest and invite you to submit original research articles, reviews, case reports, and short communications that contribute to the scientific and clinical advancement of this important field.

We look forward to your submissions.

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. Applied Sciences 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 2400 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.

Background and Objectives: The radiographic interpretation of restorative materials may be influenced not only by their intrinsic composition but also by external substances positioned within the X-ray beam path. Mineral-containing sunscreens (MSs) include metal oxides such as zinc oxide, which may attenuate X-rays and alter radiographic image intensity. This in vitro study evaluated the effects of MS and non-mineral sunscreen (NMS) on the mean gray values (MGVs) and aluminum-equivalent radiopacity of restorative materials. Materials and Methods: Specimens of glass ionomer cement (GIC), flowable composite resin (FC), and resin composite (RC) were covered with a 5 mm polymethyl methacrylate block for soft-tissue simulation. Sunscreens were applied as standardized 1 mm layers, and each material was radiographed under control, NMS, and MS conditions using identical parameters. An 11-step aluminum wedge was used for calibration. MGVs were measured using ImageJ and converted to millimeters of aluminum (mm Al). Results: Restorative material, sunscreen condition, and their interaction significantly affected MGVs (all p < 0.05). NMS produced no significant change compared with control. MS significantly increased the MGVs of GIC, FC, and RC from 67.56, 63.89, and 83.56 to 97.56, 90.00, and 104.11, respectively. Corresponding radiopacity values increased from 2.02, 1.78, and 2.79 mm Al to 3.58, 3.12, and 3.98 mm Al. Conclusions: Under the conditions of this in vitro study, the tested MS significantly increased the apparent radiopacity of all restorative materials, whereas the tested NMS had no significant effect. These findings indicate that the tested mineral-containing formulation, when positioned within the X-ray beam path, can alter the radiographic appearance of dental restorations. Awareness of this potential superimposition effect may help reduce the risk of misinterpretation during radiographic evaluation. Full article
