Special Issue Information

Dear Colleagues,

In recent years, a clear interest has developed in minimally invasive dentistry. This has been undeniably influenced by the changes that have taken place in dental materials. The properties of many materials, such as composite resins, have been changed in such a way that the scope of their application has expanded. In the same way, the development of digital dentistry (CAD systems) and finishing devices (CAM systems) allows researchers to apply more widely known materials in dentistry. Modern materials allow for the fabrication of less-invasive onlays and veneers. Materials with a similar chemical composition that are produced by new technologies have significantly different mechanical properties. Application techniques—such as the type of polymerization, use of a rubber dam, and elimination of the oxygen inhibition layer—also impact the survival of fillings and dentures.

The purpose of this Special Issue is to collate research based on the changes that have taken place in recent years in the field of the materials used in restorative dentistry. Topics of interest for this Special Issue include changes in the production and composition of materials, techniques for the production of prosthetic dentures, and new application techniques, as well as issues in the field regarding environmental impact factors and the long-term survival of dental fillings in the oral cavity. Additionally, articles are welcome to focus on the following materials: composite resins, glass ionomer cement, hybrid ceramic, dental ceramic, and zirconia. Original articles applying both in vitro and in vivo methods, alongside clinical studies, communications, and reviews, are welcome to be submitted.

Long-term aesthetic success in dentistry largely depends on the color stability of restorative materials. This study investigated the color changes (ΔE00) of resin nanoceramic and lithium disilicate ceramic restorative materials used in computer-aided design and computer-aided manufacturing (CAD/CAM) systems following beverage immersion and after repolishing. One hundred specimens were prepared from lithium disilicate (Initial LiSi Block) and resin nanoceramic (Cerasmart), and polished. The specimens were divided into ten groups according to material and beverage type (n = 10) and immersed in distilled water, cola, tea, coffee, and turnip juice at 37 °C for 3 months. Color values were recorded at baseline, 1 week, 1 month, and 3 months, and after repolishing. ∆E00 values were calculated using the CIEDE2000 color difference formula. Data were analyzed using three-way repeated measures ANOVA and post hoc Tukey and Bonferroni tests (α = 0.05). Material type, beverage type, and immersion time significantly affected color stability (p < 0.05). The highest ∆E00 observed in the resin nanoceramic–tea group at 3 months (ΔE00 = 11.39 ± 1.76). Lithium disilicate demonstrated better color stability. After repolishing, all ΔE00 values were below the clinically acceptable limit (ΔE00 ≤ 1.8). Repolishing may help maintain the long-term aesthetic success of dental restorations in the oral environment. Full article

Conventional glass ionomer cement (GIC) is a reaction product formulated from glass powders and polycarboxylic acid aqueous solution. This material has garnered significant attention in restorative dentistry due to its favorable properties, including chemical adhesion to tooth structure, biocompatibility, and sustained fluoride release, coupled with its minimal pulp irritation. However, its low mechanical strength, high brittleness, and susceptibility to cracking limit its use in stress-bearing areas of teeth. To expand the clinical application scope of GIC and develop an “ideal” dental restorative material, enhancing traditional GIC is necessary. This narrative review summarizes the main strategies for enhancing GIC, covering modifications to both the powder and liquid components. The key findings indicate that incorporating reinforcing fillers into the powder or modifying the polyacid chemistry can significantly improve mechanical properties such as compressive, tensile, and flexural strength. Additionally, some modifications help maintain or enhance fluoride release. However, the translation of many laboratory-based improvements to clinical practice requires further validation. In conclusion, while numerous promising enhancement routes exist, future development should focus on synergistic approaches and rigorous clinical evaluation to advance towards high-performance, durable restorative materials.

Objective: This systematic review aimed to evaluate material-based modifications of resorbable root canal filling materials for primary teeth, assessing how compositional changes—including bioactive additives, antimicrobial agents, and alternative base matrices—influence antimicrobial performance. Methods: A systematic search of PubMed, Scopus, Web of Science (WoS), and Embase was performed in October 2025. Search terms included (primary teeth OR deciduous teeth) AND (root canal filling materials OR root canal filling OR canal obturation) AND (antibacterial agents OR antibacterial OR antimicrobial). Study selection adhered to PRISMA 2020 standards and was systematically organized through the PICO framework. From 199 identified records, 18 studies met the eligibility criteria. Results: Most studies evaluated modified zinc oxide-based materials. Additives such as propolis, Morinda citrifolia extract, Aloe vera, and olive oil enhanced antimicrobial activity or improved clinical and radiographic outcomes compared with conventional zinc oxide–eugenol. Triclosan-containing formulations consistently demonstrated strong antibacterial effects. In contrast, chlorhexidine yielded variable results, with some calcium hydroxide–based pastes showing superior performance in its absence. Antibiotic-enriched materials exhibited high antimicrobial efficacy; however, several studies raised concerns regarding the potential development of bacterial resistance. Conclusions: Most of the introduced modifications of resorbable root canal filling materials for primary teeth enhance antimicrobial activity and their physicochemical properties in vitro. Clinical evidence is limited and heterogeneous, and therefore, its superiority over conventional materials cannot be definitively determined. Further long-term, randomized clinical trials on large patient groups, evaluating the same modifications, are needed to confirm the effects observed in laboratory studies. Full article
