Article Beyond Traditional Dentistry: How Organoids and Next-Gen Hydrogels Are Redesigning Dental Tissue Regeneration(Elsevier, 2026) Yilmaz-Dagdeviren, Hilal Deniz; Arslan, Yavuz EmreDental tissue regeneration has advanced rapidly with the development of bioengineered hydrogels and organoid technologies. In this review, multifunctional hydrogels are examined as biomimetic platforms with osteoinductive, adhesive, angiogenic, antimicrobial, and immunomodulatory properties tailored to enamel, dentin-pulp complex, periodontal ligament, and alveolar bone repair. Incorporation of bioactive molecules, including growth factors, bioceramics, antioxidants, and immune-modulating agents, has been reported to enhance tissue-specific regeneration while mitigating infection and inflammation. Stimuli-responsive designs have been utilized to enable spatiotemporally controlled delivery and degradation. Immunomodulatory hydrogels also have been shown to direct macrophage polarization, regulate T-cell infiltration, and promote matrix remodeling. Furthermore, organoid models supported by hydrogels have been employed to replicate dental tissue architecture, guide lineage-specific differentiation, and provide reproducible, physiologically relevant platforms for drug screening and developmental studies. Emerging strategies such as microfluidic organoid-on-chip systems and mechanically stimulated cultures are noted for their potential to provide more physiologically relevant models. Early clinical studies involving hydrogel-based scaffolds and stem cell constructs are discussed, indicating growing translational potential. Overall, these developments highlights that how advanced hydrogels and organoid systems can contribute to a shift from conventional restorative methods toward tissue engineering-based regenerative therapies.Article Citation - WoS: 61Citation - Scopus: 64Electrospun Gelma Fibers and P(hema) Matrix Composite for Corneal Tissue Engineering(Elsevier Ltd., 2021) Arıca, Tuğçe A.; Güzelgülgen, Meltem; Yıldız, Ahu Arslan; Demir, Mustafa MuammerThe development of biocompatible and transparent three-dimensional materials is desirable for corneal tissue engineering. Inspired from the cornea structure, gelatin methacryloyl-poly(2-hydroxymethyl methacrylate) (GelMA-p(HEMA)) composite hydrogel was fabricated. GelMA fibers were produced via electrospinning and covered with a thin layer of p(HEMA) in the presence of N,N?-methylenebisacrylamide (MBA) as cross-linker by drop-casting. The structure of resulting GelMA-p(HEMA) composite was characterized by spectrophotometry, microscopy, and swelling studies. Biocompatibility and biological properties of the both p(HEMA) and GelMA-p(HEMA) composite have been investigated by 3D cell culture, red blood cell hemolysis, and protein adsorption studies (i.e., human serum albumin, human immunoglobulin and egg white lysozyme). The optical transmittance of the GelMA-p(HEMA) composite was found to be approximately 70% at 550 nm. The GelMA-p(HEMA) composite was biocompatible with tear fluid proteins and convenient for cell adhesion and growth. Thus, as prepared hydrogel composite may find extensive applications in future for the development of corneal tissue engineering as well as preparation of stroma of the corneal material. © 2020 Elsevier B.V.
