Special Issue Information

Dear Colleagues,

The dynamic field of dental materials is undergoing profound transformation, driven by the pursuit of personalized dentistry. Technological advancements play a pivotal role, introducing refinements and improvements that enhance and broaden the applications of a diverse array of materials such as composites, glass ionomer cements, ceramics, adhesives, implants, biomaterials for bone regeneration, mechanized endodontic files, bioceramic cements, and pulpal regenerative techniques and their associated materials. This evolution is crucial for the rehabilitation of tooth structures and the regeneration of oral tissues.

The advent of new dental materials is marked by innovations in polymeric options for composites and cements, novel nanostructures in ceramic materials, advanced superelastic alloys for endodontic files, and improved manufacturing processes. Additionally, advances in tissue engineering and novel approaches to clinical research for materials evaluation further contribute to this transformative landscape.

Despite continuous efforts to enhance existing products or develop novel ones with desirable properties, progress relies on a comprehensive understanding of existing materials. This Special Issue aims to compile articles presenting recent research advances, providing readers with valuable insights into ongoing developments in dental materials. Through these contributions, we seek to deepen the collective knowledge base and offer additional perspectives on the advancements shaping the future of dental materials in the pursuit of optimal patient care.

This study aimed to investigate the effect of acidic media storage (gastric acid and Coca-Cola) on the mechanical properties of CAD/CAM materials. Three types of materials were tested: a polymer-infiltrated ceramic network (PICN) (Vita Enamic (En), VITA Zahnfabrik, Germany), a resin composite block (RCB) (Cerasmart (Cs), GC Corp, Japan), and a conventional resin-based composite (Gradia direct (Gr), GC Corp, Japan), which was used as a control. Beam-shaped specimens of each material, with dimensions of 16 mm × 4 mm × 1.5 mm, were prepared (90 in total). The specimens were divided into subgroups (10 each) and stored for 96 h in either gastric acid, Coca-Cola, or distilled water. Flexural strength and elastic modulus were evaluated using a three-point flexural strength test with acoustic emission (AE) monitoring. Vickers microhardness was measured before and after storage in gastric acid and Coca-Cola. Data were statistically analysed using two-way and one-way ANOVA, the Tukey’s post hoc, and independent t-test at a significance level of 0.05. The results showed that Cs and En maintained their flexural strength and elastic modulus after acidic media exposure, while Gr experienced a significant decrease in flexural strength following gastric acid storage (p < 0.01). Initial crack detection was not possible using the AE system, impacting the determination of flexural strength. Exposure to acidic media decreased all materials’ microhardness, with Gr showing the most notable reduction (p < 0.0001). Gastric acid had a greater impact on the microhardness of all tested materials compared to Coca-Cola (p < 0.0001). In conclusion, storage in erosive media did not notably affect the flexural strength or elastic modulus of CAD/CAM composites but it did affect hardness. CAD/CAM composite blocks demonstrated superior mechanical properties compared to the conventional composite. Full article
