BACKGROUND During the past few decades, the occurrence of superficial fungal infections has rapidly increased. As the fungal infections take longer time to get cured, concepts such as designing drugs with extended persistence and controlled release have gained attention. In this context, nanotechnology has been identified as the latest technological revolution which has opened up new pathways f...

The purpose of this study was to compare the shear bond strength (SBS) four resin-based composite materials a silicate-based cement using “no-wait” universal with self-etch (SE) and etch-and-rinse (ER) modes. Acrylic blocks (n=80, 2mm depth, 5mm diameter central hole) were prepared. holes filled BiodentineTM (BD) divided into 4 main groups (n=20) according resin type used: Group FZ250: FiltekTM...

Excessive exposure to ultraviolet (UV) and high-energy visible (HEV) light can cause sunburns, wrinkles, even skin cancer. Therefore, the development of effective UV–HEV-shielding agents is great importance human health. In this study, semiconducting graphitic carbon nitride (g-C3N4) incorporated into interlayer space mica through intercalation cyanamide subsequent pyrolysis reactions form a se...

statement of problem: despite the increasing demand for tooth-colored restorations in dentistry, polymerization shrinkage and marginal microleakage still remains a problem. objectives: the purpose of the present study was to evaluate microleakage in three different resin composites, p90, z250 and z250 xt, in class v cavity of permanent human premolars. materials and methods: standardized class ...

The mussel-inspired electro-cross-linking process allows the specific functionalization of a single electrode out microelectrode array by highly sensitive nanohybrid enzymatic biosensor, using cheap and abundant natural molecule.

The purpose of this study was to evaluate the effect of aging protocols on surface gloss of composites. Cylindrical resin composite specimens (6 mm in diameter, 1 mm thick) were fabricated and divided into three groups (N = 60): microfilled (MiFi), nanohybrid (NaHy), and nanofilled (NaFi). Specimens were distributed into four aging subgroups: thermocycling (5° to 55°C, 15,000 cycles); ethanol i...

Direct solvent exfoliation of bulk MoS2 with the assistance of poly(3-hexylthiophene) (P3HT) produces a novel two-dimensional organic/inorganic semiconductor hetero-junction. The obtained P3HT-MoS2 nanohybrid exhibits unexpected optical limiting properties in contrast to the saturated absorption behavior of both P3HT and MoS2, showing potential in future photoelectric applications.

A novel strategy for designing ultrathin polypyrrole skin-coated carbon nanotube (CNT) nanohybrids is demonstrated by vapor deposition polymerization (VDP). The ultrathin skin technology provides a stable immobilization of the mono-disperse Pd nanoparticles (NPs) on the CP-CNT nanohybrid surface, leading to a high-performance hydrogen gas sensor at room temperature.

AIM The aim of this study is to evaluate the effect of dental prophylaxis techniques on surface roughness of composite resins. MATERIALS AND METHODS A total of 36 nanohybrid resin composite test specimens were fabricated and divided into three groups (n = 12). They were kept in distilled water at 37°C for 24 hours and submitted to the finishing and polishing technique. For the prophylactic te...
