Special Issue Information

Dear Colleagues,

Oral health is a crucial aspect of overall wellbeing, and advanced materials play a significant role in improving oral care. Research on advanced materials for oral applications is essential as it aims to develop innovative solutions for addressing oral health issues more effectively.

Currently, researchers are exploring various advanced materials such as bioactive ceramics, nanocomposites, and hydrogels for applications in dentistry. These materials offer unique properties such as enhanced strength, biocompatibility, and antimicrobial effects, making them ideal for use in dental restorations, implants, and drug delivery systems.

However, despite progress being made in this field, researchers are facing challenges such as biocompatibility, long-term stability, and cost-effectiveness of advanced materials for oral applications.

In conclusion, research on advanced materials for oral applications is vital for improving oral health outcomes and patient care. By addressing the existing challenges, researchers can continue to advance the field and develop new materials that offer superior performance and benefits for oral health.

This study evaluated whether airborne-particle abrasion could be an alternative to hydrofluoric acid etching as a pretreatment for the adhesive bonding of silicate ceramic restorations. Feldspar (FEL; n = 100), lithium silicate (LiSi; n = 100), and zirconia (ZrO2; (n = 80) substrates were CAD/CAM-fabricated and airborne-particle-abraded with Al2O3 (25 µm or 50 µm of mean particle size) at pressures of 0.05 or 0.1 MPa. The controls included FEL (60 s) and LiSi (20 s) etched with hydrofluoric acid. The surface free energy (SFE) and roughness (Ra) were measured. For the tensile bond strength (TBS), surfaces were conditioned using a primer (Monobond Plus) and luted to a resin composite (Variolink Esthetic). TBS was assessed initially (24 h, 37 °C water storage) and after thermocycling (5/55 °C, 10,000×). Statistical analysis (SPSS, V29) was performed using a one-way ANOVA, post hoc Scheffé, and a two-group t-test (p = 0.05). Abrasion with 50 µm and 0.1 MPa induced the highest Ra values across the materials (62.5 ± 3.88 µm). ZrO2 exhibited a higher TBS (35.4–49.5 MPa) than FEL and LiSi. For aged LiSi, the specimens treated at 0.1 MPa showed a higher TBS (18.7 ± 9.0 MPa) than those treated at 0.05 MPa, regardless of the particle size. The etched and aged FEL showed a higher SFE but a lower TBS compared to abrasion. Al2O3 particle abrasion (25 or 50 µm at 0.1 MPa) may replace etching for silicate-based ceramics, while 50 µm is recommended for ZrO2 at either pressure. Full article

Drilling for implant site preparation generates heat, which can cause bone necrosis if temperatures exceed 47 °C for over a minute. Factors influencing heat include drill size, speed, pressure, irrigation, and tool wear. Frequent drill replacement is essential, as wear from repeated use and sterilization affects performance. This study compared three pilot drills with similar designs from different manufacturers, testing each on pig ribs for 15 perforations after 15 sterilization cycles. Researchers measured temperature increase, drilling time, and surface wear. Results showed that drill no. 1 generated more heat than drills no. 2 and no. 3, though none reached critical temperatures. Drill no. 2 took the longest to reach the desired depth and displayed the most deformation. Findings highlight the importance of adhering to the recommended operational limits, suggesting that drills should be replaced after 15 cycles to ensure efficacy and patient safety. Full article

Integrating soft components into denture design may significantly enhance the comfort of edentulous patients. Microorganisms, particularly Candida albicans, often colonize soft denture lining materials, which can release metabolic and toxic byproducts linked to the development of Denture-Induced Stomatitis. This study aimed to evaluate the effectiveness of antimicrobial agents incorporated into soft denture liners in inhibiting the adhesion and colonization of C. albicans. A systematic review was conducted through MEDLINE-Pubmed, EMBASE, and the Cochrane Central Register of Controlled Trials. A range of keywords was employed without applying a time filter to identify relevant literature. The review revealed many studies investigating various antimicrobial compounds added to different soft denture liner materials, all demonstrating the ability to inhibit the proliferation of C. albicans. All the antimicrobial agents examined exhibited a significant antifungal effect, with minimal to negligible impact on the physical properties of the denture liners. However, it was noted that the mechanical properties of the liners were modified in direct correlation to the concentration of the antimicrobial agents utilized. The successful incorporation of these agents into various soft denture liners has been documented, with nystatin being the primary pharmacological agent identified across multiple studies. While incorporating antibacterial agents was deemed successful, it is essential to note that the methodologies employed yielded varying effects on the overall performance of the soft-liner materials.
