Traumatic dental injuries in children present unique challenges, requiring evidence-based and individualized approaches. Accidental falls are a common cause, resulting in a spectrum of clinical presentations. Managing tooth injuries in mixed dentition adds complexity to treatment decisions. This case report details the conservative management of an 8-year-old with a fractured permanent lateral incisor following a fall. The child's physical status was assessed, ruling out abuse and associated neurological issues. A novel pediatric full crown fabricated from a hybrid glass material was chosen for its minimally invasive preparation and aesthetic properties. Procedural details, including crown sizing, contouring, and bonding, are outlined. One-year follow-up revealed no discoloration, pain, or adverse effects. The hybrid glass material demonstrated longevity in bonding, maintaining both function and esthetics. The discussion encompasses the choice of crown materials and the advantages of hybrid glass material. The case highlights successful conservative restoration in mixed dentition using a pediatric full crown with a hybrid glass material. This approach achieved functional and aesthetic improvements, preserved tooth vitality, and ensured patient satisfaction.

Silatranization, a specialized variant of silanization using silatrane compounds, is emerging as a powerful strategy to functionalize material surfaces. Compared to conventional silane coupling agents, silatranes exhibit remarkable hydrolytic stability and enhanced resistance to self-condensation, enabling controllable, water-independent formation of a polysiloxane self-assembled monolayer. This review critically examines the unique structure of silatranyl cages, emphasizing how the intramolecular N->Si bond and chelate effect modulate the silicon center's reactivity toward hydroxyl-decorated surfaces.

Chemical design of metal halide hybrids (MHHs) with suppressed melting point () allows access to glassy phases from their liquid-melts. Thermal phase change (crystal-melt-glass) properties of glassy MHHs (with glass transition temperature > room temperature) have been exploited for device applications. However, room temperature stable supercooled liquid (SCL) MHHs (with < room temperature), originating from glass-SCL phase change, remain inaccessible.

Polybenzoxazine (PBz)-based conducting materials have gained significant attention due to their unique combination of thermal stability, mechanical strength, and electrical conductivity. These polymers integrate the inherent advantages of polybenzoxazines-such as low water absorption, high glass transition temperature, and excellent chemical resistance-with the electrical properties of conducting polymers like polyaniline, polypyrrole, and polythiophene. The incorporation of conductive elements in polybenzoxazine networks can be achieved through blending, in situ polymerization, or hybridization with nanostructures such as graphene, carbon nanotubes, or metallic nanoparticles.

Drilling-induced damage in fiber-reinforced polymer composite materials was measured excavating four laminates, basalt (B), glass (G) and their two sandwich type hybrids (BGB, GBG), with 6 mm twist drills at 1520 revolutions per minute and 0.10 mm rev under dry running with an uncoated high-speed steel (HSS-R), grind-coated high-speed steel (HSS-G) or physical vapor deposition-coated (high-speed steel coated with Titanium Nitride (TiN) and Titanium Aluminum Nitride (TiAlN)) drill bits. The hybrid sheets were deliberately incorporated to clarify how alternating basalt-glass architectures redistribute interlaminar stresses during drilling, while the hard, low-friction TiN and TiAlN ceramic coatings enhance cutting performance by forming a heat-resistant tribological barrier that lowers tool-workpiece adhesion, reduces interface temperature, and thereby suppresses thrust-induced delamination.

The objective of this study was to investigate the physicochemical properties of hybrid coatings with titanium nitride and boron nitride nanoparticles deposited on the TiAlV medical alloy via the sol-gel process. The developed layers were intended to impart bactericidal properties and provide protection against surgical abrasions during the implantation procedure. This study focused on evaluating the microstructure (SEM + EDS), structure (XRD, FTIR), and surface properties, including wettability, surface free energy, and roughness of the synthesized layers.
