Due to its physical and biological characteristics and safety profile, hyaluronic acid is very widely used in numerous clinical conditions, ranging from its best-known use in cosmetic surgery (as a filler and for its ability to promote tissue regeneration and therefore minimise scarring) to lesser-known fields such as ophthalmic surgery, major abdominal surgery (where it is used to prevent the complication of adhesion bands) and intra-articular use. Studies were recently published in which this type of device was also used in paediatric patients for the management of inflammatory disorders of the oral cavity and teething symptoms. As this is a highly topical field for dentists, we felt it would be useful to review the efficacy and safety of the device in the paediatric population treated, and analyse any discrepancies with the results obtained in the adult population. The preparations of hyaluronic acid used in pediatric dentistry, thanks to their anti-inflammatory and angiogenic properties, proved to be very effective in therapy of oral diseases in children. Further clinical research is needed to confirm the effectiveness of these products to dispel doubts about any side effects.

Oral ulcers are prone to recurrence and often complicated by bacterial infections. Currently, antibiotics, glucocorticoids, and anesthetics are commonly employed in clinical practice to alleviate symptoms. However, these medications exhibit limited retention in the moist and dynamic environment of the oral cavity, and their long-term use may lead to various side effects or drug resistance.

In this study, a sensitive diagnosis and spontaneously photocatalytic therapy of cancer based on chemiluminescence (CL) and nanozyme was studied. Briefly, carbon nitride-supported copper nanoparticles (CuCNs) loaded with luminol (CuCN-L) were utilized to develop a microneedle patch (CuCN-L/MN). The CuCN-L probe could target overexpressed HO in the TME and actively emit CL to achieve cancer cell imaging for diagnosis.

Tear trough deformity (TTD) is a significant cosmetic concern, with current treatments relying primarily on invasive injectable fillers, which are costly and carry risks of complications. Despite the widespread use of hyaluronic acid (HA) in cosmetic applications, its poor dermal permeation has limited the development of effective topical fillers for TTD.This study aim to develop and evaluate a novel hyaluronic acid nanogel (nanofiller, NF) as a non-invasive topical filler for TTD.

Background/purpose: Dental implants can restore both function and aesthetics in edentulous areas. However, the absence of cushioning mechanical behavior in implants may limit their clinical performance and reduce the long-term survival rates. This study aimed to establish an implant cushion mechanism that mimicked the natural periodontal ligament, utilizing the properties of composite hydrogels.

Background: Extracellular matrix (ECM) is a three-dimensional (3D) structure found around cells in the tissues of many organisms. It is composed mainly of fibrous proteins, such as collagen and elastin, and adhesive glycoproteins, such as fibronectin and laminin-as well as proteoglycans, such as hyaluronic acid. The ECM performs several essential functions, including structural support of tissues, regulation of cell communication, adhesion, migration, and differentiation by providing biochemical and biomechanical cues to the cells.
