Editorial: Dental biomaterials—addressing modern challenges and shaping future procedures

direction strongly influence stress concentration and predicted failure probability, emphasizing that conservative prosthodontic solutions should be designed with reliability in mind rather than selecting materials based on strength alone.Li et al. addressed a frequent clinical limitation in adhesive dentistry: reduced or compromised light transmission during cementation (Li et al., 2025). By comparing curing modes and tracking micro-tensile bond strength over time, the study underscores that dual-curing systems may still exhibit performance differences when polymerization relies more heavily on chemical cure. This contribution supports the need to align cement selection and curing protocol with clinical access, restoration thickness, and realistic light delivery.Altankhishig et al. investigated a bioactive universal adhesive containing calcium salt monomers, reporting mineralization potential, anti-demineralization effects, and antibacterial activity (Altankhishig et al., 2025). This work reflects an important direction for dental biomaterials: the evolution of adhesives from passive bonding agents to multifunctional systems designed to stabilize the tooth-restoration interface and reduce secondary caries risk.Obeid et al. compared physical-mechanical properties of flowable fiber-reinforced resin composites and bulk-fill Giomer composites, highlighting trade-offs relevant to posterior restorations (Obeid et al., 2025). Their data provide a practical basis for selecting materials according to reinforcement strategy, polymerization behavior, and expected functional demands, and they illustrate why clinical decisionmaking should integrate both mechanical endpoints and placement efficiency.Finally, Shetty et al. explored a bio-inspired modification of mineral trioxide aggregate using sericin, aiming to improve biophysical behavior and antimicrobial efficacy (Shetty et al., 2025). Such approaches are aligned with an emerging expectation for endodontic repair and pulp-preservation materials: optimized handling and sealing should be paired with biological and antimicrobial performance to support more predictable outcomes in compromised environments.Taken together, the contributions in this Research Topic highlight several converging priorities for the field: (i) reliability-aware design and evaluation for conservative restorations, (ii) curing and polymerization strategies that remain robust under clinical constraints, (iii) multifunctional chemistries that target interfacial stability and biofilm-related challenges, and (iv) translational evidence that links laboratory performance to realistic use scenarios. We hope this collection supports clinicians navigating increasingly complex material choices and encourages researchers to design studies that better reflect the mechanical, biological, and workflow conditions that ultimately determine success in practice.
